Dark grey residue from newly purchased stainless steel kitchen items?
I have had this happen a few times now. What happens is that I purchase a new kitchen item made of stainless steel. When cleaning it, I find out that there is some kind of dark grey residue that comes off of it. The items that have done this are supposed to be used to cook or they come into contact with food.
Is this metalic residue? If not, what is it?
Best Answer
It could be stainless steel and abrasive residue created from polishing.
Method for Removal:
Hand wiping with alkaline cleaners, followed by hot water rinsing. May require multiple applications until wipe testing results are satisfactory.

Answer 2
As I said last week in the comments, I've been having this problem too, and I finally think I've worked it out.
It happens with my steel bottom pots and pans. It doesn't happen on my induction stove-top ever. It only ever happens when I use them on the electric, metal-top stove.
Basically, it seems to be metal/rust residue from the electric stove-top, rather than anything from the pot itself. Taking a cleaning rag over the stove-top gets the same gray residue.
It seems we both need a better quality stove.
