Hi Dave, You are gonna get about 50 suggestions on this one! We simply use warm water, a toothbrush---and a hand-held hair dryer on warm setting. You must get all of the soda out or the sugar will eventually become conductive. Be sure to dry board "actively". ie: don't let it just air-dry or you are right back in the same can-o-worms. Good Luck.
