I have used brake cleaner for instant start petrol or diesel not so volatile as easy start, ref deodorant i would suggest people buy as many shares as possible in makers of the cans as with government guidelines that we are getting short of water so they want people to wash less often and hearing it's being used for engines should send sales through the roof, possibly the same one if too much is used to start an engine, no problem with me as i still follow WW2 guideline of 6inch water in a bath and that only happens when the rainwater butt is full anyway, maybe we should all take up smoking a pipe again that would mask unwashed bodies.
