CLR® 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.
