Get under the Hood with a good three or four cans of degreaser and that thing will look good as new!

Lol just don't scrub it just wash with water, spray with degreaser and let sit for 15mins and then wash it off with water.

Also you might look into buying the black cover for the front to cover the gap over the radiator, just keeps tools from falling down and bending the fins
