Test the solution on a hidden area before applying to the entire surface. Apply directly to the calcium, lime or rust stain with a brush, cloth or sponge and rinse promptly with cold, clean water. Never leave CLR on an area for longer than two minutes. If the stain does not disappear, use CLR full strength and then wipe and rinse promptly with cold, clean water. Never mix CLR with other household cleaners or bleach and never reuse the bottle. Always read the manufacturer’s directions of the item you will be using CLR Calcium, Lime and Rust on to make sure that this product is compatible.  Consumer discretion is always advised.

CLR will take the finish off of aluminum and copper.

What surfaces should I not use CLR on?
DO not use CLR on natural stone or marble, terrazzo, colored grout, painted or metallic glazed surfaces, plastic laminates, Formica, aluminum, steam irons, leaded crystal, refinished tubs or any damaged or cracked surface. CLR may etch older sinks, tubs and tiles. CLR is corrosive. Avoid contact with wood, clothing, wallpaper and carpeting. Some laminated surfaces (counter tops) are coated with a synthetic surface which may be affected by rust removers; clean spills immediately.

Can I put CLR in a spray bottle?
No, CLR is acidic in nature. When using CLR it in a spray bottle, the solution could "spray back" on your clothes or in your eyes and the spray could drift.

How do I use CLR to clean a showerhead?

How do I clean hard water deposits from my drinking glasses?
Pour 1/2 warm water and 1/2 CLR into a plastic bowl and dip a clean, soft cloth or sponge into it. Apply to deposits and rub. Rinse thoroughly with cold, clean water. If it seems that CLR helped a bit but the glasses are not completely clear, repeat at full strength if necessary.

I used CLR to clean my glasses and it did not remove the deposits. Do you know why?
If it seems that the CLR did not help at all, the glasses may be etched and there is no remedy to remove the cloudiness. The cloudiness is actually tiny cuts made in the glass by deposits in the water. The only thing that may remove the etching is a jeweler’s polishing.

Can CLR be used in a steam iron?
It is not recommended that CLR be used in steam irons. It could have an effect on fabrics or interior of the iron.

Can I use CLR on my car to remove rust?
No, it is not recommended to use CLR on a car. It may drip onto aluminum or a painted surface.

The tank treats the waste by the water falling to the bottom, the solids that are lighter float to the top and the heavier waste/sludge goes to the bottom. The sludge/solids that fall to the bottom must be treated with a septic system treatment to convert these materials into liquids which then will flow to the drain field.

Frequently Asked Questions Tarn-X®:

How do I use Tarn-X?
Prior to using Tarn-X, use soap and hot water to remove any dirt or grime. Rinse with cold water and wipe dry before using Tarn-X. While wearing household rubber gloves, dip a cotton ball or soft cloth in Tarn-X and wipe on tarnished areas. For larger items, apply full strength Tarn-X to about 1/3 of article at a time, then rinse thoroughly. For heavily tarnished pieces, repeat the above process until all tarnish is dissolved. Tarn-X only removes tarnish. Always apply Tarn-X Silver Polish after using Tarn-X for optimum shine and luster. After using Tarn-X, rinse immediately with cold water and hand dry with a soft cloth.  Never leave Tarn-X on anything longer than two minutes and always test Tarn-X on a small area before cleaning the entire piece. Clean spills immediately. Some laminated surfaces (counter tops) are coated with a synthetic material which may be affected by Tarn-X.

Can I soak an item in Tarn-X?
We recommend using a cotton ball or soft cloth for the best application. However, dipping smaller items (such as sterling silver jewelry) may be easier. It is important to rinse with cold water IMMEDIATELY and do not let Tarn-X dry. Never keep Tarn-X on an item longer than a maximum of two minutes.

What types of metals can I clean with Tarn-X?
Tarn-X will clean sterling silver, silver plate, platinum, copper, gold and even diamonds. Do not use Tarn-X on poorly plated silver, silver that has scratched or marred surfaces or any item that is not in good condition. Do not mix gold and silver items together when cleaning with Tarn-X.

How important is it to rinse an item after using Tarn-X?
Rinsing with cold water IMMEDIATELY after use is one of the most important steps. If Tarn-X is not completely rinsed off, it may darken or discolor your silver. When cleaning multiple items, always thoroughly rinse and towel dry each piece before continuing to the next item.

Why did my silver darken or discolor after using Tarn-X?
Silver may turn golden or dark gray in color if Tarn-X is left on too long and/or is allowed to dry on the silver.

To remove the discoloration, fill a small bowl with 1/2 warm water, 1/2 Tarn-X and two drops of dish soap (Palmolive, Joy, etc.). With a soft clean cloth, wash the item with the mixture and rinse with cold clean water immediately. Dry the item off with a soft clean cloth. As a final step, apply a silver polish, such as Tarn-X® Silver Polish to protect the item. This should restore your piece to its original condition. For large items, make sure you clean about 1/3 of the item at a time.

What can I do if I left Tarn-X on too long?
If Tarn-X is left on too long and is allowed to dry, it may discolor. To remove the discoloration, see the instructions above.

Is Tarn-X safe to use on stainless steel?
Tarn-X should never be used on or near stainless steel, as it may stain or discolor it. This includes stainless steel flatware and sinks.

Can I use Tarn-X on my knives?
Only if your knives are silver or silver plated. Use caution! Your knives may appear to be "silver", but have stainless steel blades with silver-plated handles. If Tarn-X is used on the stainless steel blade, it will discolor it. Look on the blade of your knife for silver or stainless steel stamp or contact the manufacturer. If in doubt, test in a small, hidden area. See the following question for possibly correcting this problem.

How do I remove Tarn-X discoloration from stainless steel?
To attempt to remove the stain, immediately clean the discolored area with baking soda, applied with cold water and a soft rag or steel wool. Be careful not to scratch the surface. Also try running very cold water over the discoloration until it disappears. If this does not work, use a stainless steel and aluminum cleaner, such as CLR® Metal Clear, to attempt to remove the stain.

What is ‘artificially oxidized silver’ and how can I identify it?
Artificially oxidized silver is silver that has gone through a chemical treatment to alter its look and luster. It gives silver a smoky, almost blackened look. Do NOT use Tarn-X on artificially oxidized silver, as it will remove the artificial oxidation treatment from the silver.

Is Tarn-X safe to use on brass?
No, Tarn-X is not safe to use on brass. This is because brass is an alloy of copper and zinc, and the acids in Tarn-X effect zinc.

Why did my copper darken or discolor after using Tarn-X?
The Tarn-X was probably left on too long and/or allowed to dry. To remove the discoloration, use a copper cream or polish and follow the directions to restore the shine.

Why does Tarn-X have a mild "chemical odor?"
The odor is the active ingredients in Tarn-X coming into contact with tarnish. This indicates that the tarnish, which is sulfur, is actually being removed with Tarn-X.

Does Tarn-X harm clothing?
Yes. When working with Tarn-X products avoid contact with your clothing. Tarn-X can stain or discolor fabrics/clothing.

Where can you safely dispose of Tarn-X?
You can dispose of Tarn-X down drain or toilet.

Frequently Asked Questions Tarn-X® Jewelry Cleaner:

How do I use Tarn-X Jewelry Cleaner?
Wear household rubber gloves if you have a history of sensitive skin and always test a small area of the piece before beginning to clean.
