This sponge is an incredible natural alternative to synthetic dish sponges & plastic brushes, and is compostable in a home setting. It's made of plant cellulose for the sponge, coconut coir fibers & natural latex for the scrubber, & is sewn with cotton thread. Perfect for cleaning all your dishes, delicate enough for non-stick coatings yet strong to remove stuck on food residue. Use alongside your favorite natural dish soap for an environmentally friendly spin to your dish chores! Measures 3" x 4" We’ve added extra stitching to keep the coconut scrubber in place for longer, prolonging its lifespan. Over time it will break down, & once used up, simply tear or cut the remaining sponge & scrubber to add in with the rest of your compost to decompose naturally. After each use, squeeze out excess water & allow to fully dry, replacing every 3-4 weeks for best cleaning experience. To clean, toss in the dishwasher (top rack) as it is machine washable up to 200°F (95°C).
