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.
