rusty parts

[MI-Bill]

I have a bunch of tractor and truck sheet metal that is very rust, surface rust, mostly. I remember using some quite effective rust removal products in the past. what works best?

navel jelly comes to mind

Pretty much any product containing phosphoric acid. Rustoleum has some stuff in a squirt bottle that's pretty handy.

2X phosphoric acid. I use a delimer packed for the food service industry. you can also get milk stone remover from a dairy supply. They are a lot cheaper that the auto-body specialty products, and still dissolve the rust and convert what stays there to iron phosphate.
