Had a weird black stain on a PETG print. Maybe it was mold? It seemed pretty penetrated into material. Tried windex, all purpose cleaning spray, dawn soap and couldn't get it out. Gave a tide pen a try and it scrubbed right out easily with that!

Other filament stuck in the nozzle maybe, and it just came loose in your print? I cant imagine mold being an issue.

It's an old piece and in the kitchen.
