Brands® Calcium, Lime & Rust Remover Free & Clear, No Dyes or Fragrances, Gentle Lime and Bathroom Descaler, Removes Hard Water Stains and Rust Deposits, 42 Oz Bottle (Pack of 1)

Moved to an area with somewhat hard water and after unsuccessfully trying all sorts of cleaners, found this to work great to remove build up. I did have better luck with using an electronic scrub brush rather than scrubbing by hand too, but I'm old and needed that extra help. Product itself is great.

I used this to remove stains from toilet. Poured some in let it soak for about an hour and all stains were gone! P.S. toilet is over 30 years old and looks new again.

Removes stains, clears out aerator, shower heads. Good to keep on hand.

This stuff really works. We live in Florida and have pretty hard water that builds up around the shower area. I used it to remove the build up on my shower head and within the 2 minutes that it instructs, it removed everything. The no fragrance is a bit misleading as it may not have added fragrances but it definitely has an odor that takes a while to dissipate. After the 2 minutes of use and washing the shower head, it took about 2-3 days for the odor to leave. Otherwise, this is a good option to remove hard water build up in the shower or toilet. The instructions on the bottle are pretty clear and easy to follow as well. Overall, I'd recommend this as an easy DIY to clean bathrooms.

Excellent for removing the tide mark in the toilet bowl.

Doesn’t work as good as it used to Had the formula changed

This CLR has always worked, and the new “batch” did not disappoint. Prevented me from buying another kitchen faucet, which is not inexpensive.

Bought to remove toilet rust It worked okay but not completely
