i cover some electrical with the plastic bags and also roll up some paper towels and put them in my spark plug holes. spray everything with this cleaner called awesome and scrub down what needs to be, rinse, then spray with Gunk Foamy Engine Brite and then rinse again. i usually let the car run for a little bit with the hood open after im done just to dry itself. my engine bay isnt as clean as mike's but its not so shabby
