Wash 'N Drive Jet Wash

So what do you write about a car wash? Well you pay in the garage, put your wing mirrors in and unscrew the aerial. Type the number into the keypad and drive to the mark. Lots of squirty whirly soapy stuff happens then u drive off the wash and replace the aerial. If you have young kids this might scare them, so perhaps a useful threat for stressed parents. Here I am with an o level in English Literature writing about a car wash. Thanks Google.
