An oxalic acid (available at any paint or good hardware store) solution is the classic standard for chemically cleaning radiators, far more effective than vinegar. It was the active component in the old standby DuPont's No. 7 Heavy Duty Radiator Cleaner. And don't forget a neutralizing rinse (something like sodium bicarbonate) when you're done soaking and rinsing. It's been discussed quite a few times here, do a search and you should find some particulars.
