Very good product

I’m trying to remove a stubborn stain from the Pebbletec coating on my pool. Bought 2 pack of these pumice stone. Used the first one last night, scrubbed for 5 minutes and the stone was used up! Did see some improvement in removing the stain, but it didn’t seem tough enough.

I ordered these because I thought they were the same as I buy locally from Leslie’s Pool Supply. Boy was I wrong. The fact that the package was so light should have been a clue. One brick practically disappeared in less than 30 minutes of use. Not worth buying. Get the ones from Leslie’s. They work good and last a long time.EDITED - The customer service reached out to me and gave me a full refund WITHOUT me even requesting one. I think this shows that this manufacturer truly believes and stands behind their product.

I think this product was too soft for my application because the block disintegrated so fast. It does not scratch the tile, so that's a plus.

These pumice stones work well for cleaning pool tiles. You can see the before and after difference on the tiles. Before using, make sure to let the water level come down in the pool. If the pumice stones get wet, they do disintegrate. We use a little vinegar in a spray bottle and spray on before using the pumice stone. They are easy to use and are a great size. They do not scratch the tile. This is a much cheaper option than paying someone to clean the tile.

This product works great on our pool tile. We had a buildup of calcium and mineral deposits due to the hard water in our area. We were able to use the pumice stone to remove buildup. The larger blocks made it easier to use and now our tile looks great!

These are so light weight that they did not do the job they disintegrated way too quickly. I used them because I needed to do my pool , but I did not like that they did not last.

Worked like a charm to remove hard water lines and dried pollen off smooth tiles that wouldn't budge with a scrub daddy and elbow grease. Slap your knee pads on, get that cushion to kneel on and be sure to limber up prior and during the chore of cleaning your tiles! These were a good size and I almost made it all the way around our entire pool with one. I'd buy again.
