Simple, Affordable and consumer friendly. If you follow these steps, you can't go wrong:
1. Check in on Yelp and show your phone to the guys there and get 50% off the second best wash. Get the car washed, and they'll hand you a wet towel for you to clean your dashboard and more.
2. Once your car is washed, pull into the free vacuums and they have vending machines in case you want to buy more cleaning supplies (or you can bring your own). The fact that the vacuums are free was my deal breaker, I love that.
The vacuums are also in the shade which makes is a lot easier to clean in the hot days. It's a real shade too, not the "shade" they have with the canopy-like places elsewhere.
