take your time and cover all electrical connections, air filter, battery, mmmmm and any place you don't want to blast with water. Use plastic bags, and my favourite: aluminum foil
also look for places in your engine bay that might collect water
wipe down the really nasty spots first with cloth/brush, and then spray engine cleaner and let it sit, then rinse your engine bay thoroughly, until you are positive all the cleaner has been washed off. I prefer to use a low pressure garden hose when i do this. Anyway start your car and let the water evapourate, take it for a drive, etc etc
