I had asked this question in the v6 forum the other day, but as of last night I joined the GT club , and someone said the best way to clean the engine out was a power hose and some degreaser or the engine bay wash setting at some of the car washes. Any one have some suggestions as to what brand of degreaser and power washer to use or not use? I want to make sure I keep this one prettier than the last one I had since its so much fun to drive I havent stopped smiling since I left the dealership.
