The quality of my cleaning life shot up when Procter & Gamble introduced the Mr. Clean Magic Eraser in 2003. The Eraser is a sponge made of spun melamine foam that is manufactured in Germany by BASF (http://www.basf.com/group/corporate/de/) under the name “Basotect.” For 20 years, the foam had been used as insulation. Then it was discovered that, when wetted, the spongy material works as fine abrasive to remove dirt and grit. “On curing, melamine resin becomes almost as hard as glass”, explains BASF’s Dr. Christof Möck. “The hardness of this material is one of the secrets of its cleaning talent: like extremely fine sandpaper, the foam eraser rubs the particles of dirt from the surface.” Magic Eraser scrapes out the ground-in dirt from my scratched white linoleum kitchen floor. However, I never use it on glass. Oddly, it doesn’t work that well on scummy bathtubs.
