I just moved to St. Louis Park, and now the DIY wash I frequented in Champlin is 20 minutes away. Who knows of one closer to 169 and Minnetonka Blvd? My car is frustratingly dirty, which still gets compliments on being spotless from friends.
There is one in Hopkins off of Excelsior Blvd, just east of 169. I've gone there a few times but its really been hit or miss ( it's eaten a few of my quarters) http://www.washme.net/
