Best way to clean engine compartment?
 
Hello-

I would like to clean my engine compartment. Can I just power wash it at the car wash? Is there anything I need to cover up or protect? What is the best way to spiff up my engine compartment? Any tips/advice is appreciated!!

I just do not want to harm anything under the hood.

The safest way to do it is by hand - no power washing, just time and elbow grease.

You can carefully spray with a power washer, but you'll have to cover up all of the electrical connections and fuse boxes with plastic to protect them.

ive sprayed that engine down multiple times after offroading with mud and water all in there. no issues. the only way to get confidence is to do it. just dont use the high pressure when you squeeze while real close. just be smart. ive sprayed down the whole thing pretty hardcore so i doubt you will mess it up. dont listen to me ITS WATER. water ruins everything!!!!

Easiest way is to throw some Armour all on the plastics

There should be a few write-ups on this. Personally, I take time: cover the PCM cover/remove any air filters. I use a pump sprayer filled with a simple green mix. Spray everything, allow to soak for 15 mins, then rinse with a hose. Repeat again, scrub if necessary. Allow to air dry. Use some Meguires Natural shine or simar to get the gloss look. Personally, I wouldn't spray n wash the engine. Just my opinion.

The car wash power washer wouldn't have anywhere near the pressure of a home power washer [which can do damage if not careful].

I cleaned the engine compartment for over a decade using the coin op washers... I usually leave the engine running to keep it hot as I'm doing it. Although I suppose it is possible to damage the exhaust manifold, I typically just avoid getting too close to it.

Don't aim the spray at the intake, or the back end of the electrical connectors, but I regularly washed the engine control computer box with no ill effects.

Should you hear your engine stutter while washing, get the spray out of there in a hurry. Never happened to me, but if you are that nervous, ask your dealer's mechanics.
