CLRŽ Pro Calcium, Lime & Rust Remover:
How do I use CLR?
In a well-ventilated area while wearing household rubber gloves and standing on a non-slip surface, mix equal amounts of CLR and warm water. 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.
How do I mix CLR?
CLR can be mixed with warm water, 1 of three ways depending on the stain. For light stains and buildup, a diluted mixture is recommended. For more stubborn buildup, full strength is recommended, but only when diluted has been tried first. Diluted 1 part CLR to 8 parts warm water, 50/50 with warm water and full strength. Rarely, depending on the situation, a 1 part to 12 part dilution has been recommended and that was in a water fountain made with rocks. And always rinse with cold water to neutralize.
How do I use CLR to clean my coffee maker?
Mix one part (quarter of a cup) CLR to eight parts (2 cups) water. For single cup coffeemakers, use only one capful of CLR. Run through coffee maker as if making coffee. Rinse thoroughly by running two full pots of cold, clean water through a complete cycle. Instructions are for a regular 8-12 cup coffee maker. *Do not use CLR in coffee makers that hold water permanently. *Do not use CLR in espresso machines. *We do not recommend using any CLR products in a Kuerig, Gevalia, or Cuisinart coffee makers.
How do I use CLR to clean coffee pots, pans or tea kettles?
Pour enough CLR to cover bottom. Swish around in pot or pan. Add one cup of hot water, allow mixture to soak for two minutes and thoroughly rinse with cold, clean water.
How do I use CLR to clean my dishwasher or washing machine?
Dishwasher: Run an empty load without detergent up to the main wash cycle, (allowing enough water to fill before cycle begins to agitate) and add one-half cup of CLR. Finish cycle. Run one additional cycle with water alone to “rinse setting” to rinse machine fully.
Washing Machine: Run your empty machine without detergent up to the main wash cycle, which is where the water stops and the cycle is about to agitate. Stop the machine and add one-half cup of CLR. Finish cycle. Run one additional full cycle (wash and rinse) with cold water only to rinse machine fully. (See separate instructions for Front Loading Machines)
How do I clean my humidifier with CLR?
Pour enough CLR into humidifier to cover the bottom and use a brush or sponge to wipe away stains. Add hot water and soak until thoroughly clean. Rinse thoroughly with cold, clean water.
Can I clean the filter to my humidifier?
Use only on metal filters. Dilute equal parts of CLR and warm water into a plastic container. Dip the filter into the solution for about two minutes. Brush to loosen buildup and rinse with cold, clean water. Allow to dry.
What will CLR do to copper or aluminum?
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.
