I hate having to pay $15 for a fancy automatic carwash just so i can wash under my car. I changed the oil a few days ago and was annoyed by the mud caked under my car. I had to scrape to find the oil drain plug. Why isnt there a little system you park over at hand washes that you can turn on and it will wash under the car, like the foam brushes and vacuum cleaner. My car has very few inches of ground clearance and a wand does not get under there. this would be extra handy in the winter for de-salting the vehicle.
