My car's A/C condenser is getting fairly chock-full of dead bugs and small rocks (the bugs being plastered on and the rocks being between the fins). Fortunately no serious fin damage from larger rocks although that's probably coming given our freeways now have a bunch of gravel on them from road maintenance. Does anyone have any clever strategies for cleaning out radiators and condensers? I'd like to blow it out with a hose or something but I don't really want to to blow the stuff into the radiator, and the back of the radiator is covered by fans and fan shrouds, plus there's not much clearance in front of the engine for a hose anyway. Does this even matter? Can these things get so filled with debris that it actually affects the AC or engine cooling?
