Color tv game 6 box unknown residue

Hello everyone, i just received a nintendo ctg 6. It came with the box and i wanted to know if anyone could tell me what this residue on the box is, and how to remove it.

I am hoping that it is not mold or mildew. The box smells like any other old box for a game console. This dtuff is all over the box and i hope it doesnt spread to my other boxes.

Thanks.

Mold produces a musty smell and i didnt smell it is what i was trying to say.

you see this on a lot of old cardboard boxes. it's some colored liquid, soya maybe, that got spilled.
