Dear sir ,

Thanks for your answer , now I have doubt instead of pickling spray can I go directly to passivation spray followed by rinsing and cleaning. I need your advise and procedures if any?

It looks like iron contamination.
Actions to implement:

1. Removal of rust by stainless steel compatible brushes/disks.
2. Pickling
3. Avoid contact with carbon steel tools, jigs etc
