I used 6% vinegar, 'cleaning' vinegar' comes in different concentrations, so check what you find. I think the concentration I have is good for me.
The rust got hit with a 3" pneumatic sanding tool & 120 grit paper, I think it was. The vinegar container I used was barely big-enough. I bought it at Home Depot. I didn't have enough vinegar to submerge the entire thing. I did the major part, it had a 12-hour bath, I rinsed it off, took pics and turned it over to submerge the previously-dry parts. The female C-cups for the male rubber plugs mounting the cover are what didn't get immersed the first-time. They are now!
I'm very-happy with how it turned-out. Vinegar is much-cheaper than Evaporust. The vinegar I used was first used months ago to clean a gas tank.
