hmm, I was going to say that looks really super clean, (which it is, don't get me wrong) than after a while of looking at it, I realized its almost the same thing as mine after I clean it, just without the oil/coolant reservoir cans and the blue vac lines everywhere and the sticker in the front of the engine bay that has the warning thing or w/e on it is off, which reminds me to scrape mine off completely, I got it partially off but didn't finish, it kinda completes everything when it's off
but either way I am still curious as to what you used to clean it, I just use some detailer cleaner/wax spray, and armorall protection spray on the plastic/black stuff
