We have a couple of self-service car washes here - usually found at petrol stations. Buy a token, and the machine gives you 6 minutes with a jet wash. 3 minutes soapy water, 3 minutes fresh water. I found the pressure quite useless, it doesn't really shift the dirt, or maybe I just don't know how to use it properly.
But it's a great way to get a hose during ban periods. I find the best thing to do is bring a bucket, buy 2 tokens. Fill the bucket with the soap water, rinse the car with fresh. That's your first token gone. Do your thorough sponge business and then use the 2nd token to finish off. Drive out the way and leather it dry. All done.
It can be quite intense working against the clock though, so it's a good workout at the same time too. More than I get done at the gym, at any rate...
