CLRBrands® 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)

Low odor & effective

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.

Awesome product and works especially well on hard water stains and calcium build-up. It didn't do very muh for the small rust stains around our chrome bathroom sink drains but as we all know, Rust Never Sleeps.'Highly recommend this product!

This stuff is no joke. I used it on my shower tiles, and it cut through the buildup like butter. No scrubbing for hours just spray, wait, and wipe. It left my tiles looking like new. Definitely a must-have for hard water areas or anyone tired of fighting soap scum and grime. It’s now a staple in my cleaning cabinet!

Why did you pick this product vs others?:Removed the rust right away scrubbing lightly with cheap brushes from Amazon. Was not expecting it to work this well. This saved us a huge fine from HOA from the rust our HVAC leak has caused. We have had ac guy out here 5 times in 6 weeks and then it starts leaking overnight and the rust was so embarrassing! It is completely gone after scrubbing lightly for 3 minutes. 😃 so grateful!

Removed 99% of hard water deposits on this beautiful glass bowl without marring its surface. I will try to update with a photo of how the bowl looked afterward.

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

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.
