We have a similar problem during annealing (1000 °C). Black stains that look like rinsing stains. The only solution seems to grind the sinks, or if you are a deep drawer grind the sheets prior to drawing. Can you provide more information on your problem?

Stainless sinks are not using as much chrome as years ago and therefore tend to rust. We have the same problem with other stainless. There are many cleaners from oxidizers to citric acid this on eBay or Amazon [affil links] that work.

Cleaner for copper, brass, stainless steel, etc.: a paste of ketchup, 1/2 cup, 2 TBS vinegar in bulk on eBay or Amazon [affil links] and salt increases how well it works. Now all I need is a good homemade sealer to keep cleaned items looking sharp.

Good Luck,

This really works. We just moved into a beautiful home that was only 2 years old and the only thing wrong with it was the etched stainless sink around the drain. I tried this and it really worked, now my sink is perfect. Thank You
