Bought a Brikka knockoff from Amazon. Used it once. Got this gnarly stuff. Is this even usable?
Title. Bought it and looked good enough. I cleaned it and used it once, afterwards it had this gnarly stuff on the bottom, which hasn't appeared on any other moka I have, not aluminium nor steel. I'm waiting to have lead testing sticks delivered, but meanwhile have you guys seen this before?? I'm worried I drank the coffee...
Edit: I cleaned it with mild soap and vinegar. The spots didn't come off nor grew bigger.
