routine maintainance. but by the look of your question you're too late. how about drain and refill your radiator with the correct liqued every 500 mile for like 3000 miles.
incase you didn't know the anti freeze youre supposed to put in there hase cleaning junk in it already.

To douche your engine, mix together some distilled vinegar and distilled water, and fill your cooling system completely after it has been drained. Heat cycle your car (READ: make sure the thermostat opens, and you have the heater on full. This will allow access to the heater core). Let the engine cool, and drain your mixture, and fill'r up with your preference of coolant mixture. Be happy!

The only time I've ever used an actual flush product the radiator leaked afterwords. Did this have something to do with the radiator having 200,000 miles on it, probably. However, I suggest you flush your radiator every two years or so, and use distilled water with your coolant.
