How do Magic Erasers Get Rid of Stains?
The secret behind these types of erasers is a material commonly called melamine foam. The cavity-ridden open microstructure of melamine foam is where the second major boost to its stain-removing capabilities comes in. Apart from being able to scrape at stains with extremely hard microscopic filaments, with a few quick runs of the eraser, the stain has already started to come away.
With just a little water, melamine foam can dig in and destroy stains that other products cant touch. Kids go crazy with the crayons? Co-workers leave a trail of scuff marks wherever they walk? Erasers made with melamine foam might be just what you need. Melamine foam erasers are formed differently from other cleaning products and only need water to effectively clean most stains -- no chemical cleaners or soaps are required.
