"Naptha is my solvent of choice for removing any 'sticky' substances from chips or cards. No damage to the collectible."

Don; Isn't naptha highly flamable? Sounds like a potential for catastrophe is one is not careful with proper ventilation. One emailer suggested WD40 another suggested acetone and still another recommended a volitile chemical. My point was that if removable-type labels were applied to the cards from the start.... there would be no need to resort to chemical treatments by other traders/purchasers to remove all the sticky residue from literally dozens of cards aquired.
