Bill, This might get a heretical rise out of some of the list members, but I've been using a 50% Hydrogen Peroxide solution mixed half & half with water and sodium hydroxide crystals to bleach out those blotches for a while now with no apparent ill effects. The boards come out beautiful, like a new board. This is not the beauty supply variety but stuff available from chemical supply houses. But be careful, this stuff is potent! Gloves are a necessity or you'll end up with white hands in seconds. One application does the trick. Finish with whatever.
