Would RecommendMoved into a house with a large tile shower that had heavy soap residue build ups on the tile and in the grout lines. Followed instructions to spray the mixed solution and wait, expecting nothing to happen, and low and behold the soap scum was easily removed after the waiting period!

Best at removing Calcium Lime Rust
Would RecommendWe live in a hard water area in Southern California. This is the best kept secret to remove unsightly calcium lime rust that accumulates everywhere. Recently we soaked our shower heads in this, they turned out brand new. We have found Lowes to have the best price for the largest container. Thank you Lowes!!

Would RecommendActually bought this in error--meant to get the monthly buildup remover to unclog my 40+ year old mobile home pipes, but used it since I had it & it actually worked better!

CLR Helps with Mold & Mildew
Would RecommendI have a very strong allergic reaction to mold and would normally have upper respiratory problem caused by it. Anyway, we thoroughly clean our bathroom showers, drains, sinks, etc., at least once a week. I have tried different cleaning chemicals and finally tried CLR to clean mold. It has helped tremendously and I no longer sneeze every time I use my bathroom.

CLR! A winner every time!
Would RecommendCLR is a must-have! It works on everything from hard water, rust stains & lime deposits. All of which many people have had at some point. I also discovered it gets rid of coffee & tea stained mugs!! We always keep a jug of it on hand. Like vinegar, CLR does more than advertised!!!
