1. Cover all openings.
2. Tried Gunk Citrus Brite Engine Cleaner. NOT RECOMMENDED!
2. Gunk Foamy Engine Brite. Now this is the good stuff. Emptied the whole can on the engine, foaming up and coating everything I could get. Make sure to wipe the front fenders, wiper arms, headlights, and bumper with a wet paper towel, to get off any of the degreaser overspray.
3. Wait about 10-15 minutes, then hose the engine off with a garden hose and/or sprayer attachment. No pressure washing!
4. Simple Green degreaser/cleaner and a toothbrush. Poured some into a cup, and diluted 1:1 with water. Then went to town for 2 hours, scrubbing each component, hose, and section of the engine bay, as far as the toothbrush would reach. Prepare for back pain. Spray off each section as you go, so the Simple Green doesn't dry on it. Some people have problems with aluminum being etched by it. No problems here with the diluted mix.
5. Hose everything off, remove the covers, and drive it around to dry all the components.
6. Armor-All Tire Foam. I put maybe 1/3 of the can on the engine. It coats it pretty quickly and shines like a mofo. After spraying it on, rub all the hoses and plastic pieces to evenly coat them. I waited overnight before driving, but I'd say you could hit the road immediately.
