Removing surface rust help/question

It does look pretty nasty, but I'm gonna try my best to get all the rust off of it.
I did hit it with the sander for a bit and used some naval jelly in some spots and it helped a little bit.
Thank y'all for all the replies.
Wanted to hit it some more with the sander and a new pad, but it's a little late and I don't wanna annoy any neighbors.
