I was curious. At those D.I.Y. drive up car washes there is always a setting "tire/Engine cleaner." Is that really safe to be spraying that stuff on the engine. i would be bagging the pcm if i did it, but I was hoping that it would make an easy way to wash all the grim and oil off of my engine block before showing it to a potential buyer. Any experience with these things? this setting isn't really a powerwash because the pressure is lower, but i am just wondering if there is anything that i should avoid getting wet.
