You can have your engine compartment looking fine if you use a scrub brush and dish soap to loosen dust and dirt, Rinse with water being careful to not spray water into the air intake or to spray cold water on hot spark plugs. If you have caked on grease and grime, you can attack it with foaming engine degreaser that you can find at any parts store.
After you rinse all the crud off, go back over all the rubber hoses and plastic housings with a plastic protectant like ArmorAll(R).
Be sure to inspect all of your hoses and belts and change them out if needed.
