petecldThere are chemicals....and then there are CHEMICALS. A professional restorer doesn't use bleach. There are non-corrosive cleaners and solvents which I'm sure were used to clean the card or remove glue residue or dirt. Mastro isn't a back alley auction house, I'm sure they didn't just whip out the Clorox...
The primary goal of a PROFESSIONAL restorer it to protect a piece, stabilize any type of damage that may get worse - like a stain caused by bacteria from humidity, any yellowing, or brittleness, etc. and leave it in a more stable state from before. Bleaching is NOT a professional process, it's a destructive one that eventually destroys a piece.
