Works on rust stains
Would RecommendThis is the genuine CLR product. Watch out for other CLR branded products that are just foamy bathroom cleaners. They are fine ptoducts too, but they don't do what this original CLR does.

Disappointed, but not sure if it's the product
Purchased to remove the buildup on some vintage Jars & bottles to remove the film/fog build-up. I followed the directions but with little results. I've now have it almost full strength to see if it will help remove the age-related calcium lime film on these very old bottles and jars.
