Zep CLR Calcium, Lime and Rust Stain Remover Concentrate - 1 Gal (Case of 4) - ZUCAL128 - Professional Grade Acidic Formula

This product is much better than CLR when removing calcium growth on my humidifier. Breaks up the calcium with very little work. All you have to do is let the calcium soak in ZEP. Cannot tell you how much easier clean up was after this winter. The best thing is it is three time less expensive than CLR. Great product highly recommend over CLR !!!!!!

It worked great at my shower door that had a lot of water built up. I used with a sponge and washed it off later, it looks like new now.

GREAT DEAL

Works like the brand name and much less cost. No smell and works great for soaking shower heads.

cleaning

if deluted with water, it will not be effective on hard stains. if used un-deluted, it will remove hard stains let it sit for a while. do not use it on metals like brass, copper

I like Zep Products and this CLR didnt disappoint.I use it to clean the pipes and the filter assembly in my water filter, works like a charm.

This was a great buy. Using it to remove some debris from some old tools. This product worked great and was a great value

I have used this product for years. It's 10x better than CLR. Works great on iron from well water. Don't use in spray bottle. Use in dish soap bottle to squirt on walls, tubs ect.

Obviously some changes were made to the ingredients. . . it's absolutely useless now.

ok

Better than expected.
