Stainless steel oxide film
Stainless steel oxide film
(OP)
Can you recommend any good treatment to remove an oxide film formed on stainless steel to restore it to a shiny surface? I have tried some chemical etchants but they dull the surface due to the darkening caused by etching.
Simply polishing the surface is difficult in this situation due to particles that are brazed to it.

2. 10-15% nitric/2% HF @ 120F - 150F for 30-60 sec then water rinse.

I have seen chemical bright dips for stainless, some years ago. I don't know what was in them. Anybody else know?

I will try this and report back. (Samples are relatively expendable)
