Paperstone is made from a mix of paper and phenolic resins compressed to make a dense and very strong product and has been used to make countertops, window and door sills and a host of other products. I suspect it is much like Micarta in its ability to resist wear and water too. Even using Chosera waterstones, the amount of water splashed around is not untoward. I believe the Paper Stone bases can be rinsed safely.Probably Tom from Jende Industries can confirm this for us.
