I use a 50/50 mix of water &
simple green I cover the distributor and alternator with a plastic bag.I then use a garden hose and with the motor warm or cold I spray(using low pressure) the engine compartment down.I then spray the 50/50 mix of water & simple green onto the engine.I let it set for 10-15 min.I then using low water pressure,rinse the engine compartment down.
I have done this with excellent results and comes in handy when you show your car like I do myself
