Scrub the board with dish washing detergent and warm water. Then
shake off the excess water and dry the board in an oven set to
approximately 150 F to 200F. You can also dip a wet board into some
alcohol to get rid of the water and then just let the alcohol
evaporate off. If your water is really hard use a distilled final dip
before using either drying method. Both ways have worked good for me
but just watch out for the potentiometers etc. that might not like
the water!
