I wouldn't go spending good money trying to cleanse an old system, but if you're able to - I would try removing all radiators, draining the whole system. Flush all radiators out with a hose pipe, refit radiators, refill system.

Then if you wanted you could add a cleanser and run for a few days, then follow steps above again - refill and add inhibitor.

May take a few hours but a pretty simple DIY job.
