Under Hood Cleaning
 

What do you guys do to get a dirty engine compartment clean and shiney?:dunno: Mine's nasty and I wanted to get it clean again. I know some people use the used car lot stuff, and after it dries a few days:D it looks awesome.

I generally let the car sit over night, next day I spray the entire engine bay with foaming glass cleaner, let it sit for about 10 minutes then sray it again. I then crank the car and hose it off taking caution in not getting my distributor wet. I know I have a pushrod motor but I also use the same method on my 4.6 work truck. This way is good for light grease/oil or extremely dusty. Then after it dries, I spray everything down with Engine Brite shine spray. I think it is made by GUNK or I use S&N Products Shine It spray, they are basically the same thing.

:yup: GUNK Engine Brite

All I've ever had on any of mine....:shrug:

I use Simple Green. Basically the same process Tommy posted. SPray it on, let it sit about 10min. Maybe hit the worst places with a small hand brush and then spray off GOOD. Make sure you get it all, this stuff is potent. Then crank car to let it burn off some of teh water. At the same time the engine is warming up, if its available, take a leaf blower to blow alot of the water out of there.

Make sure to use a compressor to make sure to get the water out of the spark plug wells!

Hmm, I've never done that. :shrug:





:D

Re: Under Hood Cleaning
 

Simple Green works great. BE SURE to soak the engine compartment with water BEFORE spraying the SG - works better that way (we did some lab analysis and discovered that)...

Re: Under Hood Cleaning
 

Interesting Richard. I've lightly sprayed the engine first, but never soaked it. It does work better? Cause it works pretty damn good as is.

Re: Under Hood Cleaning
 

Basically, get the surfaces good and wet. The water enhances wetability of the surfaces, allowing the SG to get to the grease/dirt quicker and easier.

Oh, and be sure to dilute SG - about 1:4 for HD cleaning. Using it diluted actually gives BETTER results than using it straight, believe it or not.

I keep a general purpose 1:4 in my garage for cleaning duty (works great in fenderwells and on wheels), and keep a 1:10 version in the house for stubborn spots in carpet, ect.

Does SG work for oil spots on the driveway?
