What are these spots?

I ordered a few boxes of vitamin C tablets and left them in the cardboard box in my room… I’ve never really examined all the boxes but recently I noticed that some of them have these black spots on them. I tried to wipe them away with tissue but it’s stuck there. When I touch the surface with my finger it feels a little rough. Is this mould growing or is this just stain from liquid that dried up?

Toddler smooshed strawberries into his pjs. Sprayed the stain with Shout when it was still pretty fresh, let it sit for a few minutes, then did laundry on cold. Shirt came out like this. I’m assuming there’s no way to get this out? Does this look like colour bleed/dye transfer?
