Here's an interesting way. No tools needed to flip it back over.

The trans/diff etc. get sprayed with a strong soap soultion and the rest of the bottom gets a going over with a soft brush and soapy water. The soap is just Dawn dish washing soap. Simple Green is too harsh on the aluminum parts. My sprayer is ancient but you can probably still find something similar at Harbor Freight. It connects to the air compressor and has a siphon tube that you put into a container with whatever liquid you want to us as a cleaner.

The whole under side gets a good rinse afterwards and I scrub the insides of the wheel barrels before the wheels go back on the car. It's a messy job and my wife thinks I'm nutz... she's right but it has nothing to do with detailing the underside of the car.
