You could also try, (and here I must say I have never tried this personally,) giving the bottom half of the player a dip in distilled water, then working the wheel around so it frees up, maybe using a soft toothbrush or a little paintbrush to get any chunks out of the cracks, and then another dip to wash away any stuff that got loosened, and finally shaking the player to get as much water out as possible, then using a dry cloth, then pop it into a bag of uncooked rice for at least 2 days. The rice should absorb the moisture remaining.
Whatever you do, do not try to turn it on while there is moisture inside.
Good luck.
