Hi David,
Omaka is definitely worth a look. I cannot compare molasses with white vinegar, which I have never used. I know molasses works extremely well (at 6:1 mix) as long as you're not in a hurry, as it is usually 10 to 14 days before the rust disappears. I have recently heard that molasses is not good on hardened steel, like gear cogs, crankshafts etc as it causes pitting. But it is excellent on panel steel, chassis, brackets etc.
