Magic melamine sponge also called magic eraser sponge, or melamine sponge, is a kind of pure white multarticulate body with special structure made by new nanotechnology. In the early 21st century it was discovered that melamine foam is an effective abrasive cleaner. T he open-cell foam is microporous and its polymeric substance is very hard, so that when used for cleaning it works like extremely fine sandpaper, getting into tiny grooves and pits in the object being cleaned. On a larger scale the material feels soft. Because the reticulated foam bubbles interconnect, its structure is a 3D network of very hard strands, when compared to the array of separate bubbles in a material such as expanded polystyrene foam (for example, Styrofoam). magic eraser sponge Rubbing with a slightly moistened foam may remove otherwise "uncleanable" external markings from surfaces. For example, it can remove crayon, magic marker, and grease from painted walls and wood finishings, plastic-
