I understand that. I personally think cleaning is okay. For me that includes rolling bent corners and a surface cleaner to remove scuffs. I personally think that getting the card to how it was initially supposed to be presented is fine. If I buy a card and the surface is all scuffed up, it’s not my fault it was in that condition. I think trying to remove those to get it cleaner is not a problem. I draw the line personally at trimming and painting.
