PoolStone Swimming Pool and Spa Large Surface Cleaning Block

Very good pumice stone. Works amazingly to remove the white buildup I had around my pool. It just doesn't last that long. It pretty much melts in your hand while scrubbing which makes it not last long, but it is the best pumice stone I have used for my pool. Very effective, but does not last long. 5 star for effectiveness; 4 star for how long it lasts. I have a 10,000 gallon pool and it took about 4 of these to complete my whole pool

It does a great job. I live in the heat of AZ so get a lot of calcium build up on pool edges. This does a great job of removing without harming the tile. Only drawback is that you go through a lot of it as the stone is very soft.

We managed to scrub the calcium deposits off the tile trim around the edge of the pool. We live where calcium deposits are high due to the high calcium content of our water. The EarthStone worked like a charm, easier than I had imagined and we used half as much as I bought, so we have the right amount left for next years scrubbing. I could see no harm done to the tile surfaces.

I have asked for a refund, but the seller has not responded in 7 business days. The gray stones do not work for me. Photo was misleading. I asked if it was a blue pumice stone and the answer can back to me that it was blue pumice. Not the case.

This is the best stone to clean your pool tiles. It won’t scratch the tiles. It does go fast but works. Be sure to order enough to clean your pool tiles. I highly recommend it.

It is the first time I use this type of product, so it is hard to compare, but I felt the product was quickly desolved. My pool had a fairly thick buildup, so it would take some work. I never got further than 8feet along the water line. It resolves very fast. I will need at least another 8 stones to finish, but at that price...

Worked as advertised, but it isn’t magical. With some perseverance and deliberate effort, the results were quite good in removing salt build up. I’ll probably go through 3-4 of these before I’ve completely cleaned all the tile. As far as this type of product goes, it seems like a reasonable value, so take that for what is worth.

As the headline says, it works great. Problem is, I can't get anymore - anywhere!I have used other pumice "stones" before. They didn't do as good a job as this one. One of the "stones" slowly turned to mud and clouded my pool for days.
