JDWalton, The 303 works so well for this job that you really only need to degrease like once a year. Other times you can simply spray it quick with water and the dressing makes the dirt slide away.

Here's my exact recipe:

1. Spray a really good amount of cleaner or degreaser in the engine bay and let sit for about 5-10 mins.

2. Power wash dirt away. Preferably with a hot water power washer if you have access to one. If not, a car wash sprayer will do.

3. Drive around to heat your engine to evaporate water. OR use a leaf blower to dry. Especially, the nooks and crannies.

4. Spray 303 all over and lower the hood. Come back in 10 minutes and it will look like mine with absolutely NO WIPING. Use a Q-Tip to absorb any small pools of 303.

Total time: 30 minutes. I spent a few years as a member of "Autopia" detailing website. I learned all my tricks over there. If you really want to learn how to make your car sparkle check it out. http://autopia.org/forum/ Check out the "Click and brag" section.
