Consider a mobile car wash at your office. When I was still in SoCal, there were a ton of these businesses, it's very competitive there. We had 3 different crews coming to a tiny executive suite complex every week. All were very professional, including carrying their own deionized water. And a full-service wash was about $15, a relative bargain, especially considering the convenience factor.. and of course they all offered full-detail services as well. I've gotta believe such guys exist in the bay area. Track one down and get him started, and help drum up some regular weekly business so they'll keep coming back.
