I love simple ideas.

Park your car in San Francisco and then check in with Cherry using your mobile phone. Cherry then knows the location of your car. You’ll get a text when they are on their way. Washers then show up, clean your car and charge your credit card $29 for the service, including the tip. They text you to let you know when they are finished.

As you may have guessed, you can request Cherry air freshener or select from New Car, Lemon Lime and Leather scents.
