PoolSupplyTown Pumice Stone Rust Spot Stain Remover Eraser for Plaster Concrete Pool Spa

We have been so many pumice stones and they are all too soft and aren’t worth a darn. But this one is nice and hard and scrapes away everything it needs to. Thanks.

Removed small rust stains on pebblecrete pool with ease

removed a stubborn rust stain that wouldn't come out with the usual chemical treatments. NOTE: Obviously this removes some part of your pool finish in the process - so you should only use where moderate rubbing will suffice.

Does not remove stains at all from the pool. Purchased based on images and it does nothing of the kind. Do not believe the pictures, as based on my experience, they are photoshopped.

L lo use solo una ves y la mancha se fue
