[Upgrade Magic Sponge Sheets] Experience enhanced cleaning with our upgraded technology featuring convex point friction surfaces. These thin and flexible eraser sheets make it easier to clean narrow corners and irregularly shaped objects. Perfect for deep-cleaning baseboards, cooker knobs, sink faucets, door handles, wall corners, toasters, and more. [Physical Decontamination] Our sponge sheets utilize a unique polymer nanostructure that excels in particle adsorption. Water molecules penetrate the nanopore structure, allowing dirt to be automatically released without the need for chemical cleaners. Stains can be effortlessly wiped away with just water, ensuring surfaces remain scratch-free and undamaged.
