This melamine sponge can easily remove oil-based pen marks, glass stains, water stains, and tea stains. It only requires water and rubbing, so no detergent is needed, making it eco-friendly. The small size is perfect for use in the bathroom or toilet, and the cat design will make cleaning more enjoyable. It comes in two colors, so you can use them separately depending on your mood or cleaning area. This is a pack of 9 out of 12 sponges. Although it is new and unused, please understand that it has been stored at home. #sponge cleaner #kitchen #cat #cats #kitchencleaning #melamine #wateronly #fordishes #forglasses #dishwashing #dishwashing #teastainremoval #waterstains #faucet #kitchensponge #polishing #nodetergent
