I started to figure out that those auto car washes which you pay for and manually drive into, do not do a good job.  Granted most of the dirt on your car is just plain dust, no worries for mud, road salt like I'm used to in the mid-west, but still the under body needs a good scrub every time I come out of one of those.\n\nBehold the Legacy Self Serve Car Wash!  They have plenty of car ports and shaded areas for vacuuming your interior.  The thing I like about washing my own car is I can do a better job than most car washes and for a cheaper price!  Start by rinsing your car and then going for the foam brush and really scrub at the bottom and than rinse again.  I think today it took me $3-3.50 and it looks wonderful, the only thing is to remember to bring a towel so your car doesn't get water spots!
