Remove, clean (toothbrush + dishsoapy hot water), dry, polish (plastic polish), clean (alcohol), restore lettering (Wite-Out), scratch extra Wite-Out off surface of bezel when it's set enough to sink into the letters but before it's hard-dry (fingernail or edge of credit card), shoot 'em with satin clear to make them easy to clean and chip-proof the white lettering, then reinstall.
