How do you guys clean your engine?

 

usually I do it cold unless the product calls for the engine to be warm
cover alt with plastic or just avoid sprraying it.

GENEROUSLY coat engine in something called engine brite or MC Donalds Degreaser :P (lol that stuff is great)
wait 15-20 mins and rinse off.

I have acually pressure washed all of my car's engines and no ill effects so far

 

use a rag or something and wet it. dont make it too wet tho. then just clean the parts that arent electrical. Option 2 is to use seafoam.

 

Seafoam is to clean the inside of the engine, but works nicely ..... and makes a nice stinky smokescreen.
