I paid for a wash and they did a decent job, there were a few small missed spots but nothing major.
I asked when I paid for the wash about their "Rain Guarantee" since the weather forecast included the possibility of rain the next day and I was told that I could bring the car back and they would wash the car again free if it did rain. Of course the next day it did rain. I wanted to go back to the car wash the day after it rained but couldn't because I worked a 12 hour day and they were closed when I finally did get there. I went in first thing the next day to get the rain guarantee wash and they refused to do it, saying I should have come by the day after it rained.
I won't ever be going back to Mammoth.
Pros: Decent wash
Cons: Steer clear if it may rain in the next 48 hours
