While engine is cold, cover any obvious electrical gear or connections, then liberally spray some Simple Green, gently agitate with a long hair brush, then rinse with a light but thorough hose spray.

First of all you should remove the battery and electrical connection and then resin with spray and gently rub with a brush.

I've always used Gunk Engine Degreaser. Just go by directions on can with a warm engine. I've never covered wires or took out the battery, just don't spray tons of water on them and let it dry before you start it. The shop I go to always comments on how clean the engine compartment is so it must work pretty well.
