It seems car washes have been at the forefront of this green movement.  Most reprocess the  vast majority of the water they use and use biodegradable soaps.  My company recently installed solar panels at the Greenhouse Car Wash in Oxford.

  

I had no idea this service was available - thanks guciboy!  I went to the greencleanmobile.com website, scheduled my appointment and when I came home from work, my car was spotless!!  I just moved to boston and I love this city but it's been so tough to keep my car clean when it's parked on the street - but not anymore!

There must a way to get dogs or cats to lick off your car.I would think they would both do a really great job.

Is it more green just to leave your car a bit dirty?
