Calcium Releaser

This has saved the day (and look of our tile) with the horrible water issues we have....particularly with our darker tile! Definitely recommend this!

was really good, it cleans really good

I have very soft water where I live. This helps so much in cleaning everything!

The best quality, just not the best on price..... It is a really nice product and I love that it is natural stuff. I'm using it on a mirrored surface pool tiles and it doesn't remove the top surface of the tile, that normal pool tile clean will do. So I love that it keeps that mirrored surface shiny and doesn't strip it. It is the only product online that I have found to claim to be used for this purpose and really does do what it says it will do. I've turned my pool installer onto this product too. But it doesn't go real fare and you do have to use it repeatedly. Some people may find it too costly for this reason.
