Calcium Releaser & Scum Line Remover- Guardian Pool & Tile Cleaner, 1 qt. - Targets Calcium, SAVES Elbow Grease

I bought a new pool and after a few months realized that there was a ring around the tile that was thick enough that you could measure it. My pool man told me I needed to spend $1500 to have it professionally be whatever that means. I use this product And it eliminated the calcium ring around the pool tile. One thing to know is it says leave on a while but when I called and spoke to Alan, he said you can leave it on indefinitely. It continues to work. I’ll tell everybody who has a pool.

I was so excited. And it let me down. Multiple attempts and some calcium did come off but it was a lot of work for a small area. I’ll have to keep looking for another product.

Spray it in and let it dry then it hardens the calcium for easy removal. My pool has had the build up since 2018 and it helped speed up the cleaning process.

I'm a pool technician myself, and let me tell you, this is complete garbage 🗑

Tried multiple times and even with pumice stone and other scrubbing material and the scum lines did not come off.

Didn’t work per instructions given by buyer on an email they sent. Followed their instructions on small area and when still had calcium buildup told them and said to use more product!!!
