Ozone is a VERY powerful oxidizer. Please do not use ozone on your comic books. In fact, don't use it unless you really know what you are doing just in general.
Ozone can BLEACH the dye out of leather, you can turn a black white couch into a light grey couch if you aren't careful. It can also seriously damage your lungs. those "ionic breeze" shaper image fans and anything that has the word "ion" in it, are ozone generators.
Ozone is O3 which unlike Oxygen at O2 is extremely unstable, that third oxygen molecule wants to bond with something, anything, to stabilize itself, so you end up with oxygen and an oxide of whatever it bonded with. This is great if you want to get cigarette smell out of a hotel room, or skunk out of a garage since it bonds to the smell and alters it at the molecular level, but not great on anything with inks/dyes.
I know this is an old thread, but at one point I ran a small business doing odor removal of homes/hotel rooms/cars so I know a little bit about this and would hate for anyone in the future to see it as a suggestion, dust off the ol' Ionic Breeze and think this would work without damage.
