My car was completely covered in thick layers of salt. This cleaner got almost all of it off! Much better than the laser, but unfortunately the rotating bristles that are likely responsible for getting the majority of the dirt off are what I stay away from (scratches from rocks stuck in them). The air dry didn't really do much, but it was enough. Overall, great car wash if you aren't afraid of the bristles! Especially for just $5! The guys spraying your car with soap seem to have attitude problems, though :/ They also offer added things off the basic wash for $10 total. Free vacuuming with a car wash purchase, too!
