Scotch-Brite Heavy Duty Sponges are a type of cleaning sponge with a tough, rough texture. They are designed to clean and remove tough dirt, stains, and residue from hard surfaces such as cookware, grills, bathrooms, floors, and walls. The sponges are made of a non-woven synthetic fiber, which is resistant to chemicals and abrasion, allowing them to last longer than ordinary sponges. Additionally, Scotch-Brite Heavy Duty Pads can be used with water and cleaning detergents and won't scratch surfaces, making them an effective and long-lasting cleaning tool.
