If you haven't tried these sponge cloths, you're in for a surprise! They soak up spills better than rags or conventional sponges and one sponge cloth replaces 15 rolls of wasteful paper towels! These naturally biodegradable sponges are the eco-friendly way to wipe up messes. Each sponge cloth can be rewashed (in the laundry, dish washer, or by hand), and reused for up to 3-6 months. What a great ecological way to clean up!
