    Engine bay cleaning question

    I was wanting to clean up the bay in the wagon before formfest since I'll have the hood open this year, and wanted to know what the best/easiest way to clean the bay was? I know I need to use degreaser or some sort of other cleaning solution, does anyone have any recommendations? Also, I know I'd want to cover the distributor, fuse box, and remove the battery, is there anything else I'd have to avoid getting wet? Thanks in advance.

    Full strength purple power. I've use it in my engine bay a bunch of times. Just make sure you rinse it all off otherwise you'll have white residue.

    I like purple power, I also like to use this stuff we have at the shop afterwards that is like a moisturizer.

    Purple power works well, so does simple green. I have been lazy the last couple times and just went to a car wash and sprayed it out, then use that poly triple shine stuff and rinse it off with "spot free" rinse.

    Any recommendations as to whether it works better if engine is warm or cold?

    Do it while it's cold. Cracks and crevices you'll most likely have to do by hand, but full strength and a pressure washer. Cold water on a hot engine is a no, no

    Well to do it cold I'll only have access to a garden hose if that will work well enough.

    I haven't had any issue using the car wash, just let the water get hot before you start spraying it down. Been doing it that way for 10+ years.
    But Jeremiah is correct, cold water on an up to operating temp engine will cause problems eventually

    Just remember to cover up electrical stuff, filters, and whatever else needed that shouldn't get wet. I used taped down grocery bags to cover up that stuff
