Re: Another rust removing question

I've used molasses in 5 gallon buckets to giant garbage cans. It's cheap but not fast. I used to get it from the feed store in 5 gallon jugs. I did some steel wheels as well as smaller stuff this way.
I've also used phosphoric acid (concrete etch or cleaner) from the home store diluted for smaller stuff. Somewhat strong it works overnight.
