the big 3 day detail is coming up soon to get the stang ready for nice weather. i want to get the engine looking spic and span too. hows the best way to clean it? its not nasty and not oily. actually its fairly clean just dusty and such. what can i spray on the motor that will not discolor anything, wont hurt the paint if it splashes on it, wont eat any wires or hoses, etc. ? is there anything i can just spray on and rub a little and hose off? im scared to death about getting any electronics wet. what all would need to be bagged to prevent this?
