Does it need to fully dry to start it?
I'd just stick with a normal hose, nozzle and buy some P21S Total Auto Wash. Use saran wrap with rubber bands to cover the alternator & any electrical connections that are visible. Spray the P21S all over the place, wait a couple minutes, then rinse with the hose and say goodbye to any dirt/grime/oil/etc. that's in your engine bay. Finally, use some 303 Aerospace Protectant to dress-up all the black plastic in the bay.

I'll get around to ordering more P21S sometime, so I'll show you before/after pics when I'm done.

Edit: Actually, the more I look around in our engine bay makes me not even want to use a hose, even on a low setting. Apply whatever degreaser/cleaner (careful what you use - some aren't safe for rubber hoses) to the affected area, then use a wet microfiber towel to wipe it off. Dry with another microfiber towel.
