    • Great product
Size: 32 FL Oz
This product is amazing. Follow the instructions and you will have success. Especially when you have a lot of build up you may have to repeat the pricess

    • It helps, but it isn't a wonder product.
Size: 32 FL Oz
Review Image by Patrick Conroy Patrick Conroy
When I received the bottle, it was wrapped in a bag containing much of the liquid that should have been in the bottle. Not so great. Spraying it on some tiles helped remove some of the scale. It isn't perfect, and it took multiple applications to get half-decent results. If your scale isn't so bad, hit it right away; I may have waited too long. ... show more

    • Softens serious water calcification
Size: 32 FL Oz
We'd previously had our pool tile cleaned by a service. It looked great when first done, but the scale started building up. I noticed that some of it would just flake off and that started me thinking I could clear some of it as an interim cleaning. I'm now finished. After using this stuff and a combination of things to scrape with (glazed tile), it looks almost as good as after the service. For 12 hours of work (17k gal pool), I'll hope it will last several years before professional clean again. I sprayed this stuff on before working it manually, and it definetly made it easier to scrap off! ... show more

    • It works, but it takes a LOT of it to make little progress
Size: 32 FL Oz
It did dissolve the calcium - but it took much effort. It would work well on calcium buildup that is very light, but not well on heavy or thick buildup.

    • Ruined my shower
Size: 32 FL Oz
This stuff ruined my shower. I have well water and a stone tile shower and I sprayed this product on it and rinsed it off when it dried it was awful. I could not believe my eyes. It turned my shower walls and floor white and I can’t clean it off. I don’t know what to do

    • My wife likes it and she says it works on the pool scale build-up
Size: 32 FL Oz
My wife likes it and she says it works on the pool scale build-up. If my wife likes it then it must be a good product. She sprayed the scale buildup in the morning and let it sit for a while before scrubbing it lightly with a pumice stone then rinses. She says it took three treatments with heavy deposits. She has had me purchase three bottles already about two bottles to remove the very heavy buildup on the spa and wanted two more to finish the pool and keep one to spray occasionally to keep it from building up again. but they are currently out of stock. The closest price to the manufacturers price for Descale-It is from a pool supply company for $15 more than what I paid directly from Descale-It selling on Amazon, that's more than a 50% increase in price. I will wait for Descale-It to restock on Amazon. ... show more

    • No better than other products
Size: 32 FL Oz
I was disappointed in this pool cleaning product. We’ve used their industrial strength Descaling products for years with good success. This pool descaling liquid, at four times the price, was no better in performance.

    • Wear a mask when applying
Size: 32 FL Oz
Worked well on our scale on the pool. Sometimes has to apply several times to breakdown the layers. There are fumes so be careful. We've tried several products & this has been the best so far.
