Tide pen for PETG stain
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.
Ah, that makes more sense.
PETG is actually pretty porous at the microscopic level which is why the stain was so stubborn - the Tide pen has strong surfactants that can penetrate those tiny spaces where regular cleaners cant reach.
