Simply Green to degrease the engine. Lightly use a power washer. If you do not have one you can use a hose with a light spray. Dry engine bay spray it down with WD40. The WD40 bakes into all the rubber and plastic comes out great. Have been doing this for years on all the cars i have own. Never had a problem.
