leonTo most true collectors of cards (not plastic) taking something off of a card that wasn't intended to be there in the first place isn't altering. If the stain is taken off with something other than water it could be considered altering since there may be a residue or smell left on the card after the removal. I have only ever used water and a cue tip to get yucky stuff off of cards and will continue to do so.....as many hobbyists do. For full disclosure I sometimes erase pencil marks too but will usually disclose those when selling......regards
