spy,
you can find this at airconditioning supplies. this what they use to spray the fins to expel dirt and grime. or you cna use oven cleaner, they have the very same composition. you make this concoction work its way into the tight gaps and rinse it off using water.

as with other engine internal surfaces and drilled orifices that get clogged up from overcooled engines or prolonged engine oil change intervals, i highly recommend adding engine detergent to the engine oil to dissolve sludge buildup. diesel engines already use this as regular engine oil: HD engine oil which stand for high detergency and not heavy duty as what most people have a misconception with. the detergent in the motor oil will not be sufficient to remove excessive build up when the service interval has been overextended and abused. or for the next few oil changes, it does not harm the engine if you use high detergency oil. you will notice the used oil to be dirty because it is doing one of the functions of the motor oil: to clean the engine internal components
