Want to say Goodbye Paper Towels? Hydro Cloth is a highly absorbent, multi-use cloth made of natural materials: 70% cellulose (tree fiber) and 30% cotton. Also known as a "Swedish dishcloth", it can be used in place of paper towels and sponges. One towel can take the place of 15 rolls of paper towels! They are reusable, quick drying, and 100% biodegradable.
