Products - Calcium Releaser - Quart Trigger Spray, 32 FL OZ - Pool Tile Cleaner Calcium Remover, Safe on Glass, Porcelain, and Ceramic Surfaces - Calcium Cleaner - Tile and Grout Cleaner

We tried so many different products to get the build up off our glass pool tile and we were having no success. Products didn’t work and the pumice stone scraped the finish off the tile. This product did the trick and did not ruin the iridescent finish. It did take multiple applications and some scrubbing, but it did work. The first picture shows the right side before and the left side after. The second picture is the finished product!

Very little effect. Not worth the cost. Going to have to use muriatic acid.

Works great on efflorescence. I tried a lot of products including muriatic acid. Works fast may take a couple of applications minimal scrubbing

I use it to remove calcium deposits along the waterline. It took a while to figure out how to use it properly. I used pumice stone to remove the deposit and then used this product to prevent the calcium ions from re-attaching to the pool side. It takes some elbow grease but this product allows it to work.

Very good product. Works ad they say but s lot of elbow work

Even if we ignore the faulty sprayer (which is annoying on a bottle this expensive) I just didn't find this did a great job at removing the calcium build up. I could see it bubbling so it was doing something but when it came to actually removing it wasn't all that effective and still have all the stains.

It worked.

Very disappointed in the product. The results were not impressive but the price is speedy. I would not recommend.
