Default Car question, Had a head gasket blow, fixed, now trying to clean oil out of radiator

Blew a headgasket on a honda accord and have milkshake oil and water in the radiator.

Fixed the headgasket, but the milkshake is in all the lines. Whats the best way to clean the system out? I took out the thermostat, was thinking about putting a water hose in and trying to spray as much out as possible, but its pretty gunky.

Any suggestions?

Flush out as much as you can. Then pour about a third of a box of dishwashing power soap into the radaitor. Run it till it gets hot maybe a short drive to make sure everything mixes well and dump it .We used to have to do this in the big diesel engines when they would bust an oil cooler. Since oil pressure is higher than the water pressure they will always dump oil into the coolant.

We do the same thing at work. We use cascade powder, mix it in a cup with warm water to desolve it and dump it in. It works well on cooling systems that are gunked up with dexcool. (GM orange antifreeze)

The powder for the dish washing machine does work best, due to the fact that it doesn't foam.
