So, the intercooler on my car is as you'd expect despite the grill in front of it, filled with flies and bits of general matter. Does anyone have a tip on how to clean this (other than a jet washer as I'm loathe to use that incase I damage the intercooler/fins etc). Can any one recommend a good cleaner that might dissolve the dirt enough to just spray a hosepipe in there to clean it out a bit?
