The active cleaning component in a melamine pad is melamine foam, which consists of a formaldehyde-melamine-sodium bisulfite copolymer (or a melamine-formaldehyde resin condensate).

How It WorksMicro-abrasive action: The cured open-cell foam has a very hard microscopic structure. When moistened, it acts like extremely fine sandpaper to scrub away dirt and scuffs.Physical trapping: Instead of using chemical solvents, the porous foam traps and lifts debris from tiny surface grooves using only water.

Steve could have said at the very beginning it was a formaldehyde-melamine-sodium bisulfite co-polymer but chose not to.
