The secret behind these types of erasers is a material commonly called melamine foam. With just a little water, melamine foam can dig in and destroy stains that other products can’t touch. … Melamine foam erasers work well; but on surfaces that are painted, polished or easily scratched, they might work a little too well.

Do Magic Erasers actually clean?

Clean Magic Eraser is “Durafoam” sponge, advertised as a catch-all cleaning tool, capable of banishing everything from permanent marker to soap scum to beet juice. All you need to do is dampen the sponge and it goes to work on scuffs and stains, without any added detergents or cleaning solution.

Why are magic erasers bad?

They compress, pill, and breakdown with use, leaving tiny particles of super-abrasive plastic on the surfaces cleaned. For this reason, you should avoid using them in the bath or sink, where plastic particles will end up down the drain and in our water supply.
