Got this attic mint Warner's from one of my bottle buds yesterday. The label has what we think is bluing stains on it, does anyone know if there is a way to remove the stains without wrecking the label?
I would say just keave it alone. Cleaning it isnt going to help the value any.
If you want to fool with it just for your own entertainment you can wet the label then try dripping some dilute bleach on it to see if that helps. Thats how I get mold and other stains off trade cards and it hasnt hurt the printing. make sure you rinse off all the bleach well.
