Never use rice. Rice mixed with liquid leaves nasty $@$* residue on the board which is even worse than the corrosion you are trying to prevent. Take board out and use toothbrush, a $1 baking tray from corner store deli, and 99% alcohol from the pharmacy. 91% will do if they don't have 99%. Brush GENTLY in circles. GENTLY. Then put it in an oven at 220f for a few hours. THIS IS NOT TO REFLOW SOLDER!!!!! That is a BS myth and fixes nothing. We are just trying to remove all remaining remnants of water. Alcohol displaces water and is a good cleaning agent, so immersing the board in alcohol to do the brush cleaning is important. After the cleaning, into the oven for a few hours. Preferably an oven you never plan on cooking in again. Then try to turn it on after letting it cool off for fifteen minutes or so.
