Factors That Affect Reverse Osmosis Production — Pure Water Products, LLC

David M. Bauman, Technical Editor of Water Technology magagine, water filter cartridge answered a question that we frequently get about reverse osmosis membrane output in the magazine March 2007 issue. We’re including the question. The answer as a reference to our customers. Effects of temperature. Pressure on reverse osmosis.

By David M. Bauman, Technical Editor, Water Technology

Q: Since warm water produces more product with less waste, is there any reason that reverse osmosis (RO) units can’t be tied into the hot water or membrane housing blended hot and cold? Raising the temperature from 55 degrees F (12.8°C) to about 70°F (21.1°C) would be a significant increase in production.

I’m just curious as to how temperature affects RO systems big and small.

Gallons per day (gpd) RO ratings are usually tested at 77°F (25°C) and 60 pounds per square inch (psi). But in actual practice the temperature. Pressure can be very different. What happens if water temps reach 100°F (37.8°C) or more? Any damage to membranes? If I did this, the retention time in the RO tank would return water to ambient temperature before too long.

Would it tend to keep the membrane cleaner and lasting longer, as well? I suppose the easiest way to increase water production. Quality is increased pressure before the membrane. Atmospheric tanks can offer greater permeate production than permanent air-head tanks, right?

I was just brainstorming on how to improve RO production. I have done some other research, and a couple of Internet sites say that 77°F (25°C) is the optimum temperature for RO production.

One unfortunate aspect of RO advertising is that the high gpd ratings shown are rarely achieved in real-life application. Customers are upset when a rating of 75 gpd is shown on the literature I give them, when they are only getting 15 gpd. All the factors that lead to this difference need to be explained or realistic numbers must be given.

A: I couldn’t agree with your last sentence more. You have asked some very good questions. Have also raised an issue that I personally feel strongly about. Manufacturers and distributors are being irresponsible when they give you sales or technical literature with data that is practically useless to you.

Yes, there are some waters that are 77°F (25°C). They are in southern states, notably in Southern California, where much of the first membrane development was done. Hence, all the data was, and still is, presented with production figures at that temperature.

Why change it? It sounds pretty impressive, as you know, but it leads to big-time customer disappointment.

Correction Factors

Here is a temperature correction table from a TFC (thin film composite) membrane manufacturer, reverse osmosis membrane modified slightly for ease of use. The factors are meant to be multiplied by the 77°F (25°C) published gpd to correct for temperature only. There will be other factors that might reduce the actual production. Note that 77°F (25°C) is not the optimum temperature but only the one that the membranes are tested at.

If you see a gpd production figure on literature at a specific pressure that doesnt match yours, you can use a formula to make a correction. Note the meaning of the subscripts in the following formula: 1 = as shown in literature, 2 = actual gallons or pressure.

gpd2 = (gpd1 x psi2) ÷ psi1

You can also adjust for having a different total dissolved solids (TDS) reading than the one shown on literature. For every 100 parts per million (ppm) TDS you have above the TDS in the literature, you should subtract 1 psi from the «psi2» in the above formula. This adjusts for something called osmotic pressure, which works against higher production.

When customers complain

Here’s a customer complaint that should always be clarified before you even begin to address it: «We don’t get enough water.»

This can mean any of three different things and you need to find out which:

— It can mean that that the RO water, as delivered at its faucet, isn’t fast enough.
— It can mean that the RO tank doesn’t hold as much water as the customer expected.
— It can also mean that the RO tank isn’t being replenished fast enough.

The last two are somewhat related, meaning that improving one might make the complaint about the other go away.

Test case

To shed some light on these, here are a few numbers from my testing:

An RO tank 10 feet from the RO faucet delivered 1 gallon in 30 seconds. When the tank was moved to 30 feet away it delivered 1 gallon in 2 minutes and 48 seconds. Both of these included a 10-foot vertical rise from RO tank to faucet.

This is a significant difference for the customer drawing the water who wants to quickly get it into the fridge before they dash off to work.

Pressurized RO tanks apply a rising backpressure against the incoming water. This reduces production on a 1 psi-to-1 psi basis, just like decreasing inlet pressure. Therefore, it behooves you to find out if the production figure given to you by your supplier includes the tank backpressure. Or was it called «open flow,» meaning the water was being discharged to the atmosphere while being measured?

The tank will fill faster when empty and slower when it’s near full, due to the backpressure.

Averaging two «waters»

If there were no shut-off valve in the system, the pressure in the tank would eventually equal the incoming pressure and the quality of the last water produced would be of unacceptable quality and would degrade the quality of the first water. This last water would also be entering the tank very slowly.

From this you can see that the RO water in the tank was produced at a rate and quality that was an average of the first and last water produced.

When shut-off valves are used they prevent the tank’s backpressure from getting to the point where it seriously affects water quality; still, the last water to be produced is not quite as good and its production rate is not quite as high as the first water.

The degree to which this backpressure affects your production is dependent on tank size and shut-off point. ROs that discharge into a non-pressurized tank avoid this problem entirely but need a pump for repressurization.

Raising temperature

To improve TDS rejection by raising temperature is a good idea, but it is not advisable to use water from a heater unless your intended product water is not for drinking purposes.

You can, however, coil up some feedwater tubing to allow it to rise to room temperature, or you can wrap feedwater tubing around something warm, like the outside of a water heater. Your upper limit is somewhere around 95°F (35°C) before there is membrane damage. I don’t think you would improve membrane life by doing this, but you should check with the manufacturer.

As you suggest, the feedwater pressure can be boosted to increase both the quality and quantity of product water. I have seen RO systems that are suffering from low production simply because the feedwater line is too long or too small, both of which reduce pressure. Bigger is better.

Trying some adjustments

Let’s try the adjustments above on the example in your question.

You referred to a 75 gpd (from published literature) that actually produced about 15 gpd. After correcting for the 55°F (12.8°C) temperature, the production was down to 45.75 gpd. Use this for «gpd1&rdquo.

I assumed your average pressure was 30 psi (as in a 20-40 psi well pump system) and then subtracted 4 psi for 400 TDS (assumed) and 5 psi for RO tank backpressure, making the psi2 = 21 psi.

Using the «gpd2» formula above, I calculated that your production would be 16 gpd, very close to your example. In the future you can calculate this in advance. However, remember this production is for a new RO that might suffer a little with age. This is still good production for drinking water in a home.

How To Keep Your Aquarium Water Crystal Clear

id=»mod_42047790″>
Most aquarium owners decide to keep fish tanks in their homes for the beauty and serenity of the fish and bright, beautiful aquatic display. Maintaining crystal clear aquarium water is vital to achieving this goal, as any murkiness hinders this experience (and possibly the health of the fish). For anyone struggling with murky fish tank water, try these suggestions before giving up. In case you have virtually any issues regarding where by in addition to tips on how to work with water filter cartridge (simply click the following webpage), you can email us with the site. For beginners, follow these tips when setting up your fish tank for the first time. Make sure you have both an outside hang filter. An under-gravel filter suitable for the size of your particular tank. If your tank is at the upper limits of a particular filter model, consider the next size up. For the outside hang filter, make sure that you position the suction tube close to the bottom of the tank and that there are no cracks or lose components. Also, the growth of good bacteria is vital, and many hang filters have «sponges» in them to help with this process (positioned in front of your standard filter cartridge). For the under-gravel filter, if you cannot find one to fit the exact dimensions of your tank, get the one that covers the most ground. It should have slots to position filter tubs in both back corners, and try to find one where the filter cartridges are easy to pull in and out of the tube-tops for changing.

Before putting new filter cartridges in your tank, be sure to rinse off the carbon! If you don’t, you’ll get a lot of carbon dust in your water. Simply rinse the fresh cartridges under cool water for maybe ten seconds on each side (and rinse the smaller under-gravel cartridges, too). Once your filters are set up with the proper amount of carbon (individual carbon packages come with the filter cartridges-use these as a guide), have a nice bed of gravel in place that is thick enough to cover the under-gravel filter and hold your display items in place, but not so thick that it will trap too must fish waste and water filter cartridge hinder filtration. Shoot for maybe 1-2 inches, but this can vary based on tank size. One your tank is up and running, it may take some time for the good bacteria to accumulate-do not get discouraged if your water is a bit foggy at first! Good bacteria is a very important component of getting that «crystal clear» water, and squeaky-clean new fish tanks do not have any to help with this at first.

Plecostomus

Aquarium Maintenance

Regular water changes are important for water quality and fish health. Depending on your fish-to-water ratio, every month to two months is usually appropriate. You might be able to stretch it two-three months if you have a huge tank with only a small number of fish, but I wouldn’t push it. Aim for draining about one fourth to one third of the tank water. Using a suction tube and a bucket is usually the easiest way to do it (any fish store should have a suction tube). You can also use the tube to «vacuum» the gravel to suck out additional fish waste. When you fill up the tank again with clean water, do a touch-test to try to make it the same temperature as the water already in your tank (ideally, you’ll want a proper-sized tank heater that keeps the water around 82 degrees Fahrenheit for tropical fish health). Fill the tank a little bit at a time to keep from shocking the fish, and always be sure to treat the water with drops before putting it in the tank (looks for something that treats for chloramines/chlorine).

Another maintenance component would be the filter cartridge changes. You can typically wait until your filter is starting to over flow out of the tube opening, and then completely replace the cartridge with a new one that has fresh carbon. Avoid scrubbing the filter clean! You might need to clean the inside of the filter where the motor is once in a while to make sure it is functioning properly, but keeping it a little bit «dirty» allows the good bacteria to do their job of helping to keep the water clear.

As far as the glass and other items in the tank go, the easiest way to keep these clean is to have a plecostomus in your tank (sucker fish). The pleco will be able to get areas that you cannot, and it can be difficult to clean the glass yourself without scratching it. Feed your pleco algae wafers if it doesn’t look like it’s getting enough food from tank algae.

TIP: Use ammonia testers to make sure you are not accumulating any ammonia. If you are, consider a more aggressive maintenance schedule and mix the carbon with some white ammonia-neutralizing crystals (similar to carbon only white—usually found at any aquarium store).

Fish vs. Tank Size vs. Food

A very common mistake that leads to aquarium issues is having too many fish or fish that are simply too big for your aquarium size. If you are a beginner, definitely stick with smaller fish, RO membrane housing and make sure that you do research on how big certain fish can grow. Most of the time, fish will only grow big enough to fit your aquarium, but this is not always the case. If you are not sure, consult with a professional at your local aquarium store and have your fish tank size (as well as any current fish and their sizes) handy. And be sure that you are not over-feeding the fish. Use good quality flake food that is designed to avoid clouding the water, and only feed what your fish can eat within a few minutes. Always turn OFF the filter until after your fish have eaten the food, and shoot for a feeding schedule that is every-other day as opposed to every day. Most fish are fine and actually healthier on this type of schedule, and you won’t have as much fish waste in the water. Lastly, some fish, such as goldfish and catfish, are notoriously messy (poopy) and will create more challenges for tank cleanliness. Again, consult with your local aquarium store if you are not sure.

This might go without saying, but check your tank daily for water filter cartridge any dead fish! A dead fish will funk up a fish tank very quickly!

Good luck with your fish tank maintenance. Please feel free to share any extra tips and comments below!

Which Is The Best Ro Water Purifier For Home Use In India

Before choosing a purifier, it is important to understand the water purification technologies available and which one will be good for you. It is because the one-type-fits-all formula doesn’t work while selecting a water purification system. Different water purification targets different types of water conditions. Let’s have a look at it.

Water is known to have the best solvent properties which can dissolve pollutants, bacteria, viruses, and other harmful chemicals that make it polluted pretty quickly. Sometimes these contaminants can cause various waterborne diseases which can be life-threatening. If you want to protect your loved ones from such kinds of hazards then a water purifier is a compulsory appliance for your home.

However, before settling down, you must know which one is the best model of water purifier that can fulfill you and your family’s needs! This also depends on what kind of filtered water purifiers. Their functions you are looking for.

Before I provide you the detailed research and the list of best water purifiers that can be found in India based on their performance, quality of water dispensed, price, and brand, let’s check out what kind of filters are available for home use in India.

Types of Purification Technologies Available in India:

Before choosing a purifier, it is important to understand the water purification technologies available and which one will be good for water treatment parts you. It is because the one-type-fits-all formula doesn’t work while selecting a water purification system. Different water purification targets different types of water conditions. Let’s have a look at it:

Ultraviolet or UV Water Purifiers

The primary concern for most Indians have regarding the water that is used for drinking is the widespread water-borne diseases. Water sources serve as the breeding grounds for microorganisms which can lead to many life-threatening illnesses.

Many people boil water in order to filter out these impurities. Sometimes boiling is not enough as the water will still be prone to contamination. At that point in time, Ultraviolet or UV filters come in handy as the wavelength destroys the microorganisms’ DNA. It can kill the bacteria, prevent them from reproduction, and save you from getting sick. However, it can deactivate the organisms, it is unable to separate other particles, or remove bad taste and odor.

If you are opting for a UV purifier, then there is nothing to be worried about regarding its safety. Water which is treated with UV is completely safe for drinking. It doesn’t alter the water composition or even use any harmful chemicals.

Ultrafiltration or UF Water Purifiers

UF purifiers are pretty similar to RO. It also uses a semi-permeable membrane to separate impurities from water. But, these two products are not entirely the same. UF uses a membrane with larger pores, i. In the event you liked this informative article in addition to you would want to be given details concerning water filter element (https://notes.io/RBH2) kindly go to our own site. e., 0.01 when compared with the RO membrane which uses 0.0001. Larger pores mean that the water can pass easily without any pressure, unlike RO.

UF filters don’t hold back or even wastewater like RO. If you are worried about electricity or water wastage then UF is the best option for you. However, it is not recommended for hard water sources or water which has high TDS.

Reverse Osmosis or RO Water Purifiers

RO water purifiers are the best choice for almost all Indian households. These purifiers are so famous in India that the term RO has become a synonym for water purifiers. If these purifiers are combined with other filters like UV, UF, and MF, they can remove almost all commonly found impurities like mud, sand, bacteria, viruses, excess dissolved solids like magnesium, calcium, and heavy metals like lead, arsenic, etc. It is also the most important. Reliable technology in the water purification method.

Here are some water purifiers you can use at home:

Applying It To The Flaky Patch

See how to keep your skin healthy. Radiant with these tips.

TLC

Your skin is a bellwether to your overall health. If you’re not healthy, it will be reflected in your complexion. But that doesn’t mean you should neglect your skin even if you’re feeling fine.

In this article, we cover a wide range of skin-care topics — such as hands and nails, makeup, perfumes and colognes, blemishes, and even homemade skin-care aids. We’ll start with the basics. The sun’s rays can burn you even if the air feels cool, and sunlight reflected off water or snow can be particularly powerful.

No matter what your skin type is, use a protective sunscreen when you are in the sun; don’t expose your skin for more than 15 minutes. Don’t forget to use sunscreen on your face. The back of your hands because these are constantly exposed to the sun’s rays.

Always remove your makeup before going to bed.

If you usually wear makeup, give your skin a chance to breathe one day a week by going without.

If your face tends to be puffy in the mornings, keep skin freshener, astringent, and cotton pads for your eyelids in the refrigerator for a quick pick-me-up.

Rub moisturizing lotion on your legs before applying shaving cream for a smoother, softer finish when removing leg hair. Men who have normal to dry skin can also benefit from this technique.

Use a humidifier to lessen the drying effects of indoor heat on your skin in the winter.

Take baths in the evening to avoid exposing your skin immediately to outdoor air.

In the next section, we’ll shift from the basics to something more specific: caring for your hands and nails. If you care for them properly, you’ll feel healthier. Consider these suggestions:

When nails chip excessively, it may be caused by the use of nail polish remover. Leave your nails unpainted for a few days to see if the condition improves.

When you’re preparing anything with lemon and vegetable juices, which contain acids that are hard on your fingernails, rinse your hands often under cool running water.

To break the habit of nail biting or cuticle chewing, carry a tube of cuticle cream with you. Whenever you start to nibble, put the cream on your cuticles instead. You’ll promote healthy nails. Possibly break yourself of a bad habit.

To rescue nail polish that has become hardened or gummy, place the bottle into a pan of boiling water for a few seconds to get the polish flowing smoothly again.

To soften cuticles, soak hands in a solution of 1 cup warm water and 1 teaspoon of dish-washing liquid.

For an emergency treatment for dry, chapped hands, soak your hands in a bath of baby oil mixed with sesame oil.

Apply hand cream before putting on rubber gloves to prevent your hands from drying.

While hands and nails are important, the face is of greatest concern for many people. In the following section, we’ll provide several helpful makeup hints. These no-nonsense tips should help you avoid problems with your makeup:

In the winter, use oil-base makeup to protect your skin against dry, cold air. In the summer, switch to a water-base foundation to help moisturize your skin.

When your mascara begins to dry out, run hot water over the tube for a minute to soften the remaining mascara inside.

After applying mascara, dip a cotton swab in a little baby powder and sweep it over your lashes. Then apply a second coat of mascara. Lashes will appear longer and fuller.

Dry milk can be used as a makeup remover. Mix 1 teaspoon milk powder with warm water. Apply to your face using a cotton ball. Rinse clean.

Perfumes and colognes — the topic of our next section — are a key part of skin care. After all, they’re what make you smell good. Here’s how to make your eyes sparkle:

Cover puffy eyes with cotton pads soaked in milk, and relax for 10 minutes. Or dip 2 tea bags in boiling water for 2 minutes, then let the tea bags cool slightly. Meanwhile, heat 1 teaspoon olive oil until it’s warm, not hot. Using an absorbent pad, carefully dab the oil around your eyes and on your eyelids. Lie down, and cover each eye with a still-warm tea bag for 10 minutes. Remove the tea bags, and gently wipe off the oil with tissue.

Keep an emergency eye-relief kit in the freezer. Dip cotton swabs into cool water. Store them in a resealable plastic bag in the freezer. To relieve tired eyes and reduce puffiness, roll the swab under your eyes.

Refresh tired eyes by laying cotton pads moistened with witch hazel over closed eyelids for a few minutes.

To reduce swelling caused by overexposure to the sun, place thin, freshly cut slices of cucumber over closed eyelids for a few minutes. Here are some details:

Apply perfume and cologne to your skin rather than your clothes. Chemicals in the perfume may weaken fabric or change its color.

A dab of petroleum jelly rubbed over your wrist or water treatment accessory [squareblogs.net] neck where you’ve put perfume or cologne will help the scent last longer.

Apply perfumes and colognes before putting on your jewelry. The alcohol and oils in your favorite scent can cause a cloudy film on jewelry.

Blemishes are enemy No. 1 when it comes to skin care. In the next section, we’ll examine how to treat and prevent them. Try one of these ideas for your next bath:

To revive tired muscles, add several handfuls of Epsom salts to your bathwater.

To soften skin, toss 2 to 3 teaspoons of baking soda into the tub.

For a soothing and fragrant skin massage, mix equal parts of peanut oil, camphor oil, and castor oil and add to the tub as you draw the water.

Make yourself a soothing milk bath by adding 1/2 cup dry milk powder to warm bathwater.

To get rid of flaky skin or the remnants of last summer’s tan, add 1 cup of cider vinegar or the juice of 3 fresh lemons to your bathwater. Slough off dead skin cells with a dry sponge or brush.

Blemishes

Blemishes are a reality for most people at some point in their lives. But they can be treated and, to some extent, prevented. Follow these tips:

After your facial-cleansing routine, apply milk of magnesia with a cotton ball or pad to any acne blemishes. Let dry, then rinse off using cool water.

To treat pimples and discourage blemishes, apply a mixture of calamine lotion and 1 percent phenol (available at a drugstore).

Apply lemon juice to blackheads using a cotton ball. Leave the juice on overnight. In the morning, rinse your face with cool water. Repeat every night for 1 week.

For acne outbreaks, apply lemon juice on a cotton pad several times a day to dry up pimples.

Spread mayonnaise over your face, and let it dry for 20 minutes. Rinse off with warm water, then follow with a cold water splash. This treatment will help tighten pores.

Honey speeds healing by killing bacteria. For an overnight blemish remedy, dab honey on the spot and cover with a bandage.

We’ll conclude this article by looking at a variety of homemade skin-care aids. Check out these homemade skin-care ideas:

For an easy weekly facial sauna that unclogs pores, add a few tablespoons of your favorite herbs to water and boil for several minutes. Remove the pot from the heat, and use a bath towel as a tent while you let the steam rise to your face for 3 to 5 minutes. Then rinse your face with very cold water to close the pores.

This treatment works well for normal to dry skin: Mash 1/2 of a banana in a bowl. Add 1 tablespoon honey and 2 tablespoons sour cream; mix well. Apply to your face, leave on for 10 minutes, then rinse with warm water.

For a toning and cleansing mask for normal to oily skin, add 3 tablespoons finely ground oatmeal to 3 tablespoons witch hazel to form a paste. Apply to your face and allow to dry for 20 to 30 minutes, then rinse with warm water.

To make a toning mask, combine half of a small papaya, 1 egg white, and 1/2 teaspoon lemon juice and mix in the blender until creamy. Leave the mask on your face for 20 minutes. Then rinse with cold water.

For a cleansing mask for dry skin, mix the yolk of an egg with 2 teaspoons mayonnaise and 1/2 teaspoon lemon juice. Apply to your face. Allow to dry for 20 minutes. Wash off with warm water.

For a skin-tightening mask for normal and oily skin, whip an egg white, apply to the face, and allow to dry. Rinse off after 20 minutes. Avoid this treatment on dry skin, where it may be too harsh. Remove flaky skin by dipping a cotton ball or pad in milk. Applying it to the flaky patch. Rinse with cool water.

For a softener for rough areas, such as your feet, knees, and elbows, mix a paste of 1 tablespoon finely ground oatmeal and cold cream. Apply it several times a week, and rub gently as you wash off the paste with warm water.

For another softener for rough areas, mix 1/4 cup table salt, 1/4 cup Epsom salts, and 1/4 cup vegetable oil. Stir constantly as you mix the ingredients. Massage the paste into rough skin for several minutes. Remove by bathing or showering.

Repair cracked and chapped feet or hands by covering them with a thin layer of petroleum jelly, then wearing cotton socks or gloves while you sleep.

You can see that skin-care is a detailed matter, but we’ve shown you that there are many clever ways of keeping your skin healthy and looking great. If you have any type of questions regarding where and the best ways to utilize water filter cartridge (vimeo.com), you could contact us at the web-site. Spray on the skin as desired to freshen.

Removing Oil Stains Can Be Messy

Oil stains are smooth operators; they can sneak up on you when you least expect them. Follow these stain removal tips to erase these slick spots from any material or surface. After letting the absorbent work, brush (the method of using a stiff-bristled brush to sweep staining material up onto a piece of paper) the powder off the fabric. If a stain remains, sponge (the method of using a dampened pad to apply light strokes, moving outward from the center of the stain) with a dry-cleaning solvent such as Afta Cleaning Fluid. Apply a dry spotter. Cover with an absorbent pad that has been dampened with dry spotter. Let it remain in place as long as any stain is being removed. Change the pad as it picks up the stain. Keep both the stain. Pad moist with dry spotter. Flush (the method of applying stain remover to loosen staining material. Residue from stain removers) the area with the dry-cleaning solvent. If a stain persists, sponge the area with water and apply a wet spotter with a few drops of white vinegar. Cover the stain with an absorbent pad moistened with wet spotter. Let the pad stay in place as long as any stain is being removed. Change the pad as it picks up the stain. Keep both the stain and pad moist with wet spotter and vinegar. Flush with water and repeat the procedure until no more stain is removed. Allow to dry.

How to Remove Hair, Lubricating, Mineral, Vegetable, and Automotive Oil Stains From:

Acrylic Fabric, Cotton, Linen, Modacrylic, Nylon, Olefin, Polyester, Spandex

Blot excess spill as soon as possible. Apply an absorbent. Allow it to soak up remaining spill. After brushing out the powder on the laundry stain, sponge the area with a dry-cleaning solvent, K2r Spot Lifter or Afta Cleaning Fluid. Apply a dry spotter and cover with an absorbent pad moistened with dry spotter. Let it remain in place until no more stain is removed. Change the pad as it picks up the stain. To help loosen the stain, occasionally tamp (the method of bringing a brush down with light strokes on stained durable fabrics and materials) the area, blotting any loosened material. Flush with one of the liquid dry-cleaning solvents. If you beloved this report and you would like to obtain much more info concerning reverse osmosis membrane system (bbs.pku.edu.cn explained in a blog post) kindly visit our own web-page. If any trace of the stain remains, sponge the stain with water and apply a wet spotter and a few drops of ammonia. Tamp the stain again, blotting with an absorbent pad. Flush the area with water. Repeat until no more stain is removed. Allow to dry. Wipe the surface with a cloth or sponge dipped in warm sudsy water. Rinse well. Wipe thoroughly dry. If stain remains, make a paste of 1 pound strong powdered cleaner, 2 cups powdered chalk, and 1 gallon water and cover the stain. Or, cover with a paste made from fullers earth (an absorbent clay used for removing grease from fabrics) and hot water. Leave the paste on overnight. Rinse with clear water. Repeat if necessary. Allow it to dry, then brush off the powder. Or apply Tannery Vintage Leather Cleaner & Conditioner. Repeat if necessary. Tannery Vintage Leather Cleaner & Conditioner will also condition the leather, or use Fiebing’s Saddle Soap. Rinse well and wipe dry with a clean cloth. If any residue remains, mix a poultice of water, powdered detergent, and bleach. Apply to the stain and cover with a dampened cloth to retard evaporation. After the stain has been bleached out and the oil removed, rinse thoroughly with water and allow to dry. Apply to the stain. Allow to dry. Brush off the powder. Repeat if necessary. Rinse thoroughly in hot water. Dry with a soft clean cloth. On some oil stains, rubbing lightly with a suede stone will remove any residue. Dip a clean cloth into ground cornmeal. Rub into the stain with a circular motion. Gently brush out the powder with a wire brush. Repeat if necessary. If stain persists, brush stain with lemon juice and hold in the steam of a boiling teakettle for a few minutes. Brush with a wire brush. Dip a cloth in only the foam. Apply to the stain. Rinse with a clean cloth dampened with clear water. Polish or wax as soon as possible.

Removing oil stains can be messy, but with these removal techniques, spots are sure to slip away.

How To Make Wet & Dry Spotters
Dry spotter:

To make a dry spotter, combine 1 part coconut oil (available at pharmacies and health food stores) and 8 parts liquid dry-cleaning solvent. This solution may be stored if the container is tightly capped to prevent evaporation of the solvent. Mineral oil may be substituted for the coconut oil, but is not quite as effective.

Caution: Dry-cleaning solvents are poisonous and may

be flammable.
