The discoloration and yellowing of your piano keys is inevitable. Many factors play a role and some can be prevented by giving proper piano treatment.

Piano keys whitening

To whiten your discolored piano keys, do the following:

  1. Put a thin layer of mild, white toothpaste on the piano keys.
  2. Wipe away the leftover toothpaste with a cloth slightly moistened with whole milk and dry immediately.
  3. Indirect sunlight after cleaning can help prevent white piano keys from yellowing. 
  4. Beware: Plastic keys on the keyboard will discolor if exposed to sunlight, so always keep them covered when not in use.
