How do you wash your Engine bay?

Alright, now you all have me wanting to spray the dust off with a hose at least (maybe pressure washer without the pressure). What I haven't seen talked about is engine temperature and on/off.

I assume you don't want to spray a hot engine because you could crack something with the cold water. Also assume you'd want the engine and electrical off. Do you drive it down the road after to heat up the bay and dry everything off like a dishwasher? Do you crank it right up after and go for a drive or let it air dry for a bit?

 

only wash cold
Blow off with leaf blower or compressed air blower after or everything water spots

 

I'd be curious what TCCN does with particularly dirty engine bays when he has to do repairs under there...

 

Thanks, guess I have an excuse to add a battery powered leaf blower to my milwaukee collection!
