    • Works like a dream.
Size: 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.

    • Did it work? No and yes. Please read below.
Size: 32 FL Oz
Didn't work on water line on my San Juan Fiberglass pool, but worked exceptionally well on black algae on my water fall. It turned the algae to powder and I glad that worked for black algae. Any recommendations on white scaling on fiberglass pools?

    • 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

    • Use on glazed tile. Don’t waste your time or money using it on porous stone or rock.
Size: 32 FL Oz
To be fair, I do not have glazed tile on my pool. I have some type of stone at the water line. The calcium, or whatever the buildup is didn’t come off with the descaler. It worked to some extent, but after three applications a lot was still visible. It may work great on glazed tile, but like the directions say... it’s not made for stone. Using it didn’t cause any damage to anything, it just didn’t work well. ... show more

    • Descale-It plus a bit of elbow grease does the trick
Size: 32 FL Oz
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. ... show more

    • Didn’t do a good job on scale and bleaches your grout.
Size: 32 FL Oz
I will have to re-grout where I used this in my pool. Bleached my dark gray grout white. Doesn’t clean very well because it will get into every crack and crevice and turn white.

    • 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.
