I use TIDE liquid mixed with a little (Very little.... /images/graemlins/supergrin.gif) water. Then I spray it on with those pesticide jugs. Make sure the engine is warm. Then scrub, and rinse off later.
I have also tried Simple Green, but I had a bad experience with it on electrical connections in the past.
