if you can find it, use CD-2 Engine Cleaner and Detailer. Comes in a kit with two cans (one cleaner, one detailer). You dont' need to wipe anything, this stuff rocks. Here's what I had after 20 minutes (most of which is just waiting) and no rubbing or wiping what-so-ever:



The thing was spotless. I can't beleive how hard it is to find it though. The cleaner is a spray-on, let soak, then rinse product. The detailer is a spray on a dry engine bay, then let setup on a warm engine product. Excellent stuff.
