Have you ever wiped a vessel and found that the wipe had excessive black debris? This is common on mechanically polished vessels, especially when they have not been properly cleaned and prepped. This is often polishing debris from ground-in stainless steel particles and abrasive residue. Any comments on your experiences would be helpful!
