Gday Cobb, so I found this YouTube video called immaculate comics and they sell a product called immacuclean  also the user has in depth videos about cleaning.    what I was wondering is do you think immacuclean is a something like  salicylic acid? If you use wet you will need to dry it press etc if you do it but…I tried Stridex pads on this comic didn’t lose colour didn’t do much but remove some dirt. The books were very old 20+ years. Did see it a bit brighter. just
