Stainless Steel
If stainless steel knives are stainless then why do I have a stain on one of my stainless steel knives?
shareBecause it's bootleg stainless steel?
shareThat is possible, I will check for forgery marks.

Stainless means it won't rust. Is the stain on it brown or white?
shareIts a brown stain. Does it come off?
shareCame across this a little while ago:
Pour a little baking soda over the stain if still noticeable, followed by a small amount of vinegar, which will bubble up. Rub the mixture first with a soft cloth, then with a plastic scrub pad if the cloth doesn't remove the discoloration. Follow the grain of the steel as you scrub to avoid scratching the surface. Wipe the surface with a clean damp paper towel, following the grain of the steel.

But yeah, stainless actually does rust. I have a stainless steel firearm that developed rust over time. It didn’t rust real bad as it would have with ordinary blued steel, but it did develop a few spots here and there.
I looked up the composition of stainless steel, and it’s said to have a Chromium content of 10.5% or greater. But I wonder if some of the stuff that you’re getting these days from overseas has a lower content.

"Despite its name, stainless steel can and does stain. So first and foremost, for clean stainless steel surfaces, these are products and techniques to avoid: ... – DON'T use steel wool, steel brushes, or highly abrasive scrubbing pads—these can cause scratches or leave a residue of small particles that may rust."
"How do you get stains out of stainless steel?

It's sold without any stains. What you do with it after you buy it is your own business.
