Not quite nothing left behind. If the spray has any ionic content at all, it will leave a little bit of residue that promotes slow corrosion, or non-volatile petroleum residue that provides an insulating layer on the contacts if allowed to accumulate. Whether it works or not depends on how many time it has been done before, IMHO. But try it.
