This is one thing that I have been wanting to do since I've bought my truck, but due to where I was driving it was pointless. Now I'm able to I've read how guys just cover there battery, fuse box an alternator an just spray away. Still kinda worried about that idea.. Anyway is there anything you guys use to spray on the engine to get the dirt an grease off or just use water? Thanks for any help. An sorry if this isn't in the right section.
Think of it this way, your vehicle was designed to operate in the rain right? Snow? Storms? etc....
I've been washing my 07 Ram since day 1 under the hood. I use Citrus de-greaser from Home Depot. It's made by Zep? Anyway, you buy a squirt bottle with it and dilute 50/50. Squirt away on dry cool engine bay. Then, wash off with hose water. Start truck and bring to operating temp. Then, if you prefer, use some Armor All and make it look new. Spray the AA on and walk away. Do not rub it off. Come back in 1 hour and it looky like new!
No covering anything, no worrying, no problems after 4.5 years!
