It was posted before that you leave your engine running while washing it. I got a few questions about this point. Will it short anything out, like if theres water going from both wires to the battery or anything of that matter? And also, do you leave the engine running while spraying the Black Magic or any other tire shine? LAstly, if you dont even need to have it running let me know too, im in need of an engine wash!
PS...theres a coin machine wash right down the road from me, but can I use a regular garden hose with a head on it that shoots a powerful spray?
