I'll address these separately.Quote, originally posted by blue_can »So the #40 mentioned is mainly for cleaning the plastic areas of the engine. What about the metal areas especially if for example an oil spill then attracts dirt. In the past I've found that sometimes the black marks from the accumulated dirt in the oil spills is very hard to remove.The #40 is a plastic/vinyl polish and cleaner. It can be used on any plastic or vinyl interior, and any exterior cladding or rubber seals. It can also be applied to all plastic and hosing in the engine bay.For the oil marks, I would go with Simple Green. Spray it onto the area or onto a rag and wipe away. It is a cleaner/degreaser and not harmful at all. One thing I do when cleaning the engine bay is covering the air intake opening and the battery terminals with plastic baggies. Then I hose the engine quick with a light spray. Then I spray the whole thing down with Simple Green. This will allow it to penetrate other areas you cannot normally reach. Do this in the street of course, then let it sit, take a large bristle brush and scrub the areas you can reach. Then hose off lightly, dry everything with a towel and apply the wax and #40 to the specified areas. Also you may want to hit up your local auto store for a set of bristle brushes. They look like industrial toothbrushes, the nylon bristle is good for getting hard to reach areas and the brass one is good for small rust spots or white marks on manifolds and such.You can find #40 at

Maybe the #40 is a better prodict to use for that.Quick Detailer Spray is for painted surfaces, i.e the body. You could use it on the frame and subframing under the hood and strut towers, but I find that under the hood, Simple Green on the metal parts works best. If the area is painted such as the underside of the hood and strut towers, etc. Throwing a coat of wax by hand helps in keeping them clean and clear in the long run.
