I am doing a remodel on a house built in the 20's. A new boiler system is to be installed. Some of the old radiators will be reused in parts of the house and new infloor heat added in other areas. I am concernd that there is possibly old scale or other contaminants in the old radiatiors which may clog the new system. What is the best way to clean out the old radiators.
