Clean the outside to make it look clean? is that what you ment?

oh haha.. I use simple green to clean alot of the nasty stuff.

Yup, simple green does wonders.

1. Take plastic bags and put it over the alternator/sensitive electrical components.
2. Spray simple green all over.
3. I Let it sit for a quick minute
4. I have my water hose shoot a very light spray all over the engine bay, make sure not to aim at one area for too long.

That's what I do at least.

Also, have an old toothbrush ready for persistant stains.

I wash motors all the time at work and have yet to have one not start when I was done. Sometimes they misfire because either there is water in the distributor or in the spark plug holes. Simple green, cover the distributor with a plastic bag, pressure washer, and blow out the spark plug holes when you are done. Be careful not to hit the belts with a narrow spray pattern as there is more force than in a wider pattern and it can tear up the belts a bit.

i use rabbit tail and love juice.


degrease, soak pressure wash.
keep engine running, stay away from injectors, and coil packs.
shoot away, use common sense.

yea just make sure you dont directly spray your alternator or dizzy, thats all..oh haha dont hydrolock your motor by spraying into the intake either.

just don't do it on your driveway or just be prepared to house that off for a bit. Oh, and it smells horrible too.

I don't hose anything, because I don't want the chemical-laden runoff going down the storm sewers. I just use Simple Green, a bunch of those shop paper towels and a few toothbrushes.

use simple green engine & wheel

I did what you said, except i went at it with a pressure washer at the DIY car wash. Some places got degreaser with hot water option to get rid of all the crap too.

honestly i dont even do simple green. i use 50/50 dilluted rubbing alcohol and microfiber cloth. it cuts into the grease/dirt easily and i dont have to worry about simple green being too strong or having to spray it down with water after and hitting issues later.

i also found turtlewax ice really shines up the rubber parts. unlike armorall that doesnt last long against water nor heat, turtlewax ice seems to be significantly more durable.

I use those high pressure water hose from the car wash. Never had any problems, just do not spray the valve cover too much. I got some water in the spark plug once and the car misfire.

It's funny you say that...I use 50/50 alcohol mix as well....to clean the INSIDE of my engine. (and help prevent detonation) :bigok:

Kewl. Probably gets much cleaner with a pressure washer.
