Hello! I have a 1965 Ludwig Pioneer snare WMP.  It has been stored since the seventies in a case with a soft red liner.  Between 2 of the lugs, the wrap has some pink discolored areas. I think this redness may have bled from the case.  I have tried to remove this with Novus #2, but it hasn't seemed to help. Does anyone have any ideas about how I can restore this wrap?
