Nothing is infected Apo, I'm looking at normal here.
Pick off the hard rust with a small, sharp tool.
Get some coarse steel wool and some powder sink cleaner, give it a good scrub under running water.
Dry it and put it back in the vinegar.
No fluid is magic, it is just a substance that helps you to get the job done. If I look at the pics of this blade I can still see a lot of what appears to be rust. I suggest you pick this off, scrub it off, as I have advised above.
When the thing is clean, dry it thoroughly and then either stain it or spray with WD40.
