Removes even stubborn stains from various surfaces. Simply moisten the eraser with water, lightly squeeze it without wringing it out. Effortlessly erase stains with light pressure. Reusable multiple times against dirt, marker stains, streaks, fingerprints, limescale stains, etc. Once the sponge is worn out, just throw it away. Also works wonders on stainless steel surfaces with a bit of dish soap. Not recommended for polished stainless steel surfaces.
