Why not use the classic, oxalic acid? Follow with sodium carbonate as a neutralizer. But whatever you do don't use muriatic which is a dilution of hydrochloric acid and which can rapidly dissolve the solder in your radiator. Vinegar (acetic acid) is an old time treatment and also should be followed with a neutralizer.

Search this forum for oxalic and you'll find specifics, it's been discussed often.
