Low odor & effective

Works great

The intimated this would remove the hard water marks on my shower glass. I tried it. Doesn't work as well as promised.Pretty much no better or worse than other foaming cleaners.

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!

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.

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!

Disappointed. We have hard water and our toilets are horrible!! Wish it would have worked better but others have had great results!

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