PVA is a high-tech synthetic material that is lint free and resists mold and mildew better than a regular sponge or towel.

Wring it out before putting it back in the container. Specifications for Shurhold PVA Sponge: Manufacturer: Shurhold Color: Black Package Contents: Shurhold PVA Sponge Shurhold 210: Sponge PVA
