I used this car wash instead of a regular manual car wash, as it was too cold and wanted to wash the salt and dirt off. I tried the "Ultimate Laser Wash". I was pleasantly surprised. The force of the touch-less water pressure, did a good fine job. The blower dried the car sufficiently. I used a towel for the interior door jamb area & inside door edges.
I think what helps is when driving into the bay for "pre-wash", go slow as possible and when exit light go on while blow dryer is running, also exit slowly, which the signs tell you to do for best results.
It works well and enclosed cleaning is a plus. During these frigid cold winter months, no hand washing for me. read more
