The thin All Purpose Sponge is made from pure plastic free, woodbased cellulose - nothing else. Use it for cleaning house as well as body. Holds soap and liquids very well, making it soft and nice to use and feel on your skin. The thin sponge is very ideal for wiping surfaces like tables, mirrors etc as it leaves no dust when used. The All Purpose Sponge is reusable and washable. Wash it standing in dishwasher topdrawer or in washing machine if very dirty. Washing machine shortens sponge lifespan. Waste Management: Pure cellulose can decompose with biowaste. Ask locally if cellulose is ok in your biowaste bin, or put it in non-recyclables. Don't put dirty cleaning products in biowaste, as compost is supposed to go back to nature.
