Rain Tunnel Car Wash - Coolidge

I've used the automatic wash many times and have found it does well. But now I'm not so sure, after my last experience. My car was only dirty from the windstorms mixed with rain. Dried dust spots covered my car. So it should have cleaned off easily using the automatic washer lane. Instead, it did hardly that. My car was still very dirty after using the Supreme Wash Cycle, or $6 option. Very disappointed. I ended up doing it myself at home. I'm thinking I'll not return.
