This eco-friendly sponge cloth set is made from natural materials, which are entirely compostable and biodegradable. They are re-usable and suitable for everyday use, such as washing dishes, cleaning bathrooms, etc. Made from a blend of cotton and natural cellulose, they are super absorbent (around 15x to 20x their own weight), machine washable (up to 200 times), and when you’re done with them, they can go in the compost.
