Rust removal and pan seasoning

So how to deal with a new french iron pan with significant rust? Here's what I did:

I removed the rust with vinegar and some effort

Then I put in some potato peels and water and cooked for 15 minutes.

Then I discarded the skins and water and wiped it down and heated some oil in it.

Then wiped it down and it was ready to go: a rust free, seasoned, iron pan!
