Below is a list of Touchless Car Wash manufacturers from Minneapolis, Minnesota. A touchless, touch-free or no-touch car wash is a popular alternative to car wash varieties that use brushes and bristles. Touchless washes use high-pressure water nozzles and cleaning solutions to remove dirt from a car’s exterior. Only water and cleaning solutions, often based on mild acids and alkalis, come in contact with the car, and therefore there is no risk of scratching the finish or leaving brush marks.
