Rehook Expanding Cellulose Sponge is made from wood pulp and cotton, abundant and renewable natural materials. These robust sponges last longer than synthetic sponges and, when disposed of, are fully biodegradable. The sponge can absorb and retain 10 times its dry weight in water, making it perfect for using along side our other cleaning products, such as Rehook Universal Bike Cleaner.
Simply add water to your cellulose sponge to instantly expand it to its full size. Don't worry when it dries out, just get it wet and it'll be ready for use again. If it needs a freshen up, it can be machine washed at low temperatures. Once it's reached the end of it's life, chop it up using scissors and add it to compost so it can biodegrade.
