CLR Brands® Calcium, Lime & Rust Remover Free & Clear, No Dyes or Fragrances, Gentle Lime and Bathroom Descaler, Removes Hard Water Stains and Rust Deposits, 26 Oz Bottle (Pack of 1)

This works exactly as expected from the brand name product. It came quickly and in great condition. I used it on a bathroom sink with a lot of mineral build up. I used it as directed on the bottle, and it removed all the crud.

Unbelievable! I thought my drinking glasses would just always get and stay cloudy. This stuff is amazing. I bought it just to clean my glasses. It pretty much wiped off the calcium deposited with the sponge soaked in 50/50 CLR and water. Last time I tried clean the glasses I went through an awful process of mixing various ingredients and scrubbing with little to no impact.

It worked pretty good. No perfect but alot better than it was. I've tried lots of different products and this worked the best.

Works great! I like that you can just spray a small amount instead of having to pour out a bunch and waste it.

Works great!

Good stuff. Works to get hard water build up completely off.

Does not work at all for buildup inside toilet bowl. Over a period of 30 minutes, I repeated the instructions 4 times. (Sprayed and let stand for 2 to 3 minutes.) Each time I then used a scrubbing sponge for a few minutes with zero effect. The buildup is easily felt and was not diminished at all, dispute my efforts. Here is a photo of how the bowl appears and it is the same before and after. If are trying to resolve the same issue, I cannot recommend this product.

CLR. Does what it does.
