Engine Degreaser, What to cover up? Options

[JoKeRkId613]

My engine area is VERY dirty. There's a lot of dust and grease all over the place and I found a spray can of degreaser in the storage room of my house. The instructions say to spray everything and then turn the car on and leave it on for 10 minutes. It then says to turn it off and spray the whole thing with water to get the stuff off. How effective is the degreasing thing? Will I see a huge difference? My main concern is spraying the whole thing... I don't think I should spray the whole engine compartment. Some parts must be covered up before I spray the thing... What parts must I cover up that shouldn't get sprayed with degreaser and/or water???

ANY ADDITIONAL INFORMATION WOULD BE APPRECIATED :-)

Also... when doing the detailing of the bay after the rinse and drying, be sure to use a silicone based protectant (i.e. :Aromor All Tire shine, 2001, Meguires, ect...) on your hoses and electrical covers. This will not only water proof the parts, but will also prolong the life of the hoses.

But above all....stay away from ' CD-2 ' enginge detailer!! It does nothing more than act like a MAJOR dust and grime magnet!!! I've tried this product twice on numerous locations (Jax,FL. & now Dirty,Dusty Vegas), with lousy results.
