Wool Dish Sponges are a natural & compostable alternative to synthetic dish sponges. Use them the same way you would use a normal dish sponge - lather, scrub, rinse, & repeat. Layout to dry between uses. When you first start using the wool sponge it will naturally felt up into a smaller size and shape, but it will not shrink indefinitely.
Wool is naturally antimicrobial, and will not shed microplastics.
