Pool & Spa Cleaner (32 FL Oz)

I used this for my bathtub. It had hard water staining that regular cleaning products wouldn't remove. I also used it on my shower tile and it came out nice a clean.

I read the other reviews and it was easier to understand how to use this cleaner and what to expect. I followed a video that suggested I cover the sprayed area with plastic wrap- to avoid it drying too prematurely. It was very helpful to have a substance that was not toxic as you have to spend quite a bit of time scraping it off. I did have a "white film" issue - I think the calcium deposits just cling to the surface if you aren't diligent about washing it off.

That’s not work at all

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.

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.

So disappointed, Iv purchased the bathroom descale it in the past and it was powerful, this stuff doesn't effect the scum at all, lol, 😔 live n learn

My pool water got out of balance and I had a mess of scale in a about a week. Gotta keep tabs on that water! Descale-It has done a great job of removing it. It does require some elbow grease for the tougher spots (scratch-free sponges and plastic bristle brushes). Like other reviewers noted, when you spray it on, it goes to work. Bubbling and fizzing. I did find that for my grout, which is a bit dark but not actually colored, the dissolved scale will get into the grout and leave it gray/white when it dries if all I use is a sponge. However, if I follow up with a stiff bristled brush and plenty of water, it pulls that busted-up scale right out.

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.
