The method I use works fine. Get some auto degreaser (mine is 50/50) and a pressure washer. Turn on the car and let it run. Spray on the degreaser and let sit for a min. You keep the engine on so the degreaser and heat up and do work. Use pressure washer on any setting and spray it down. our washer is set on high at all times. Take a skewer and a cloth to get the tight spots. Leave hood up and car running for ten mins. I use Black Magic Tire dressing for under the hood to get that killer shine. We detail cars for auctions and for show rooms everyday 7days a week. Just dont be stupid.
