Washing engine bay?, how to? Options

[NYp8tBaller07]

Well as title says, I want to pressure wash my engine bay but I'm kind of nervous to do so as I feel I will short something out. As far as I can think I would want to cover the air filter, disy, alternator, battery, fuse box...anything else I should be aware of?

But when I wash the bay I do it like this:

-Go to a do it yourself car wash
-Leave the engine running, pop the hood
-Use the "degreaser setting" to spray the bay down(get the block, trans, firewall, battery, head, intake mani, AVOID the dizzy) The engine may misfire if you get the dizzy wet, BTW(if so, dont worrk, just avoid it more, this is why its running, the heat will dry it out faster). Get the wheels while you're at it. also give the bay a quick once over before you change steps.
-Use the "wax" setting and rinse off the bay. HI pressure everywhere except close to the dizzy
-Soak the bay down with armor all.
-Close hood
-Was car as normal.
