Collection storage/display advice. Mold?

My Super Darius II came in mintish codition with rusted staples. I swapped them out for the staples from a spare manual of a cheap mahjong game.

^ I assumed it was sun-fading, but the result looks nice, especially since it echoes the fading of the Arm&Hammer box.

There is a word for fading color/blending hues... "ambre"? No, that's not it.

Dammit.

I am a germophobe and I can't see past the two yellow spots on the manual.  You need bleach and rubbing alcohol stat.

Yeah I've tried that. Some bleech and rubbing alcohol but some minimal yellow spots still remain on 2 of my manuals.  I'll either keep them in plastic sleeves to keep them from contaminating the rest or just chuck them .
