What cleaning product caused this to happen?

I’m unsure what happened here. This is a stainless steel kitchen sink. My cleaner has been recently and now I’ve noticed this patina / staining. Has anyone any idea what it is and how I could get rid of it. I’ve tried bleach and lime scale (Viakal) remover.

Fat stains on Parquet floor

Hopefully it can help someone else who doesn’t know where to start.
