This is sort of on topic, because washing the car ought to be a do-it-yourself job, but I dislike doing it especially in very cold weather like now. So, especially in winter, I used to take the car to a nearby automatic car wash, the sort with big fluffy rollers which rotated while detergent solution was squirted out, and this did a perfectly good job in a couple of minutes for maybe £2-50 or £3.
But they all seem to have vanished around us, and all you can find are "attended" washes where some unfortunate youngster squirts a hose at your car for a few seconds and then charges you a fiver. If they do a good job it takes a lot longer, and if they don't do a good job I resent paying more than for having something done that could be done better and more quickly by machine, indeed a machine that I know used to be installed all over the place.
Is there some health and safety issue that has passed me by, or do some fully automatic car washes still exist, if you search hard enough?
