CleanStone Expanded Glass Block

Absolute Magic!

These blocks are absolute magic. I used one to remove limestone from sealed granite. It also removed a rust stain from the same slab. Amazing, highly recommend!!!

Effective Product!

This worked well on some of the granite markers we tend to spend less time focusing on (as opposed to the typically older marble markers who see their own cleaning process.) It worked great and our 8 year old enjoyed using it after applying some endurance cleaner as lubrication. Happy to have a solution to some of the mineralization that can collect on granite.

Cleanstone

Regrettably, I have not yet used the Cleanstones that I purchased, but that will occur soon as I prepare family headstones for Memorial Day. What I can say is that I did my due-diligence before my purchase and am certain your product will be of significant benefit on several of the headstones that have been heretofore very challenging to clean.
