Ok i just wanted to see the right steps on how to clean ur engine bay the right way, And what would be the best stuff to use?

 

i use citrus orange degreaser with the engine running, i let that stuff sit for o 15 min or so then i power wash it off, comes out good. im sure you can use a hose if you want? this is what i do so i dont know. many car washes offer engine "steam cleaning" which is what i do. degrease and powerwash.
