General rules for melamine
Melamine stains when food is left to dry on it, and the fix is soaking rather than scrubbing.
The maker's own method is a long soak, four hours or overnight, in warm water with dishwashing granules, or an oxygen releasing product. Then a non abrasive pad.
What ruins melamine is the instinctive response: bleach and a green scourer. Both dull the surface permanently, and a dulled melamine surface stains faster afterwards.
Check the label
Melamine manufacturers are explicit that bleach, green scouring pads, steel wool and metal scourers must not be used, because they dull and scratch the surface. The recommended treatment for staining is an oxygen releasing soak or a long soak in warm water with dishwashing granules, then a non abrasive pad.

Melamine is a thermoset resin, used for tableware and as the surface of faced boards and worktops.
It stains rather than absorbs
Food left to dry on the surface bonds to it, and hard water minerals and protein build a dull film. Manufacturers describe this as the main cause of melamine staining.
Soaking is the manufacturer's method
An oxygen releasing product, or an overnight soak in warm water with dishwashing granules, then a non abrasive pad. That is unusually specific advice and it works.
Bleach and green pads are excluded by name
The maker names bleach, green scouring pads, steel wool and metal scourers as things that dull and scratch the surface.
The board version has an edge problem
Melamine faced chipboard has a paper backed surface over a chipboard core, and liquid reaching a cut edge swells the core permanently.
