Magic eraser (melamine foam)

详情

Magic eraser made by melamine foam.

In the early *1st century it was discovered that melamine foam was an effective abrasive cleaner.The 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 bubbles interconnect, its structure is more like a maze of fiberglass strands, when compared to the array of separate bubbles in a material such as expanded polystyrene foam (for example, Styrofoam).

Rubbing with a slightly moistened foam may remove otherwise "uncleanable" external markings from surfaces. For example, it can removecrayon, magic marker, and grease from painted walls, wood finishings, plastic-adhering paints from treated wooden tables, adhesive residue, and grime from hub caps. If the surface being cleaned is not sufficiently hard, it may be finely scratched by the melamine material. The foam wears away, rather like a pencil eraser, leaving behind a slight residue which can be rinsed off.
