Brilliant product

This is wonderful! The Cling formula keeps the product right where it's put. I used it on a bathtub bottom with lots of built up calcium & mineral deposits and it was amazing. Took off all those deposits & stains and cleaned the bathtub up to a level I never thought it would reach. Everything else I tried just ran off into the drain before it had a chance to really soak in and work. No fragrance, and easy to use. Read more

Great for hard water

About the only thing that removes hard water stains. It isn't powerful enough to spay and wipe off but it means less scrubbing. Make sure you ventilate well. Read more

Works great in showers

I like that this stuff comes out as foam and almost stays. I used it on a shower handle and it ate up all the soap, hard water spots and most importantly calcium build up. Read more

Works!

We live in Arizona and hard water ruins glass and stone. This is the best cleaner out there for hard water. Harsh smell but worth it. Read more

Works Good! Smells Bad!

This really removes hard water stains and sediments from toilets, sinks, and showers. It’s slow to clean but it does work. Unfortunately it’s smells terrible and will leave the room smelling like this for a few hours. Read more
