If it is oxidation, try baking-soda and salt first.
Then vinegar and salt.
Then, again, warmed up or even boiled.

If it is something organic or “plastic-like” try fingernail polish remover.
Then try rubbing alcohol.
Then them them again warmed up (both are flammable so be careful).

Last, try 180grit sandpaper just enough to expose the design and value.
