Sorry to thread hi-jack, but I did not see the need to make a new thread.
Todd, I noticed that the engine bay in that tutorial was only slightly dirty. Would the same cleaning technique be effective in an engine bay like mine?

There is some fairly heavy crud in there. I bought the truck recently like that and it has been bothering me. This thread was the perfect opportunity to ask. Thanks!
