Have you used a magic eraser sponges for spots on carpet?
Magic erasers are made from a form of melamine foam. Technically, it's a formaldehyde-melamine-sodium bisulfite copolymer foam made by the German company BASF. It was invented as an insulator and fire retardant. That it cleans like the dickens was a happy coincidence. Melamine is an extremely hard polymer and it's what gives things like Formica laminate its rigidity.However, when it's pumped full of air something interesting happens. Despite the fact that the material itself is very hard, the tiny strands that make up the foam's matrix feel soft to the touch. On a microscopic level, those rigid little strands are very abrasive, like super fine grit sandpaper.
