Detailing an engine bay covering parts?
I have a small auto detailing business and I want to start offering detailing the engine bay. I've strayed away from it because it makes me nervous. Today I want to test it on my car, a 2001 Ford Escape XLT V6 3.0L. My dad always told me to make sure to cover the alternator and battery before spraying chemicals and water into the engine bay. I can cover the battery but the alternator is impossible to get to without jacking the car up and taking the rotar off. Is it ok if it gets a bit wet? I'll be using an electric 1800psi pressure washer and some gunk engine degreaser from auto zone. There's a bunch of videos and some say never to spray water in the engine, some say only use a garden hose, some say **** it, cover the battery, spray degreaser on it and spray it down. I'm getting mixed messages.
