Default Engine Bay Cleaning Recommendations?

I'm still fairly new to the BMW world and all of the extra electronics under the hood have me a little hesitant to start sudsing and rinsing away. What are the proper steps/precautions to do a basic engine bay cleaning/dressing? Keep in mind I am a complete detailing amateur. Thanks.

-Chris

Here is my (and a lot of others) routine for engine cleaning.

First off, the items I'd recommend picking up (almost every online retailer will carry them).

Cleaner: P21s Total Auto Wash
Soap: Any Soap you like. I prefer Poorboys Super Slick n Suds, but again, just about any will work just fine.
Dressing: Chemical Guys Fade2Black or Meguiars hyper dressing (diluted). I prefer the CG F2B. its an aerosol and finishes dry to the touch after a couple minutes.

Anyway, prespray the area you're working on w/ the P21s TAW. Agitate using a soft bristled brush and soapy water. Rinse GENTLY w/ water. Start motor and allow engine to dry off. Once its all dry, apply your dressing.

I cleaned my Engine Bay with p21 Total Auto Wash. Its a really good all purpose cleaner.

Same procedure here. I go one step further and use my Metro Vac-n-Blo to ensure everything is dry and then apply a little 303/Fade2Black to dress it.

I run the engine for 10-15 min to dry it up. A technique I learned from Wes_R's excellent detailing write-ups in his threads.

Go to coined operated pressure washer and pressure wash the engine. It won't hurt anything. I did this about once a year for 10 years with my 1990 Carrera 2 and about once a year for 8 years with my 2002 BMW M3. Never a problem. I wasn't even careful about where I sprayed the water.

Do these dressing attract dust and dirt like a magnet or are the dry. One step better, is there any dressing that shine or give the new look that actually repel dust/dirt adhesion?
