Description
These sponges are made of vulcanized rubber. A miniscule percentage (less than 30 grams per 500 kilograms of sponges) of mild soap is impregnated during the manufacture of the sponges. Their unique pore size effectively removes dirt, soot, and smoke residue from a variety of substrates including walls, books, wood, paper (including wallpaper), textiles, and metal. Each sponge measures 6 x 3 x 1-3/4 in.
