Abstract An apparatus and method are herein described for cleaning and waxing automobiles in commercial "car wash" operations without any need for mechanical buffing or polishing as, for example, with brushes. The surface of the car is first covered with a water soluble, agitated liquid cleaner which has been at least partially foamed. Then, the surface of the car is blasted with water soluble beads under sufficient pressure to apply a frictional cleaning motion to the liquid cleaner, but with insufficient pressure to damage the car surface by excessive abrasion. After the blasting step, the liquid cleaner and water soluble beads are rinsed by the application of a high pressure water spray thereto. If it is desired to wax the car surfaces, microcrystalline beads of dry, water soluble, carnauba wax are blasted against the car surfaces with sufficient pressure to cause frictional buffing and polishing of the surfaces, but insufficient pressure to damage the surfaces with abrasion. Then the car surfaces are rinsed with a water diluted silicone solution to remove any excess non-buffed wax and the surfaces are finally rinsed with clear water to remove any remaining water-solubles. In one feature of the apparatus, nozzles are provided which both oscillate and are directional so that dispensed material is directed in an oscillating manner at the front portions of the car as the car approaches the nozzle and at the rear portions of the car as the car passes and moves away from the nozzle.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
99 words
A method for treating the surfaces of automobiles in commercial car wash operations, or the like, comprising the steps: a. applying a water soluble, thickened liquid cleaner to the surface of the car; b. blasting the surface of the car with dry water-soluble pellets comprising soda ash beads coated with sodium metasilicate, said blasting to be applied with sufficient pressure to generate frictional cleaning movement to the thickened liquid cleaner, but applied with insufficient pressure to damage the car surfaces by abrasion; and c. rinsing the car surface with water to remove the cleaner and water soluble pellet material.
Claim 2
Independent Claim
99 words
A method for treating the surfaces of automobiles in commercial car wash operations, or the like, comprising the steps: a. applying a water soluble, thickened liquid cleaner to the surface of the car; b. blasting the surface of the car with dry water-soluble pellets comprising soda ash beads coated with sodium metasilicate, said blasting to be applied with sufficient pressure to generate frictional cleaning movement to the thickened liquid cleaner, but applied with insufficient pressure to damage the car surfaces by abrasion; and c. rinsing the car surface with water to remove the cleaner and water soluble pellet material.
Claim 3
Dependent Claim
68 words
A method according to claim 1 with the additional steps of: a. blasting the surface of the car with wax under sufficient pressure to generate a frictional buffing/polishing action but with insufficient pressure to damage the car surface by abrasion; e. rinsing the car surface of excess non-buffed wax by applying a water diluted silicone solution; and f. rinsing the car of any remaining water solubles with water.
Claim 4
Dependent Claim
16 words
The method according to claim 2, wherein the wax comprises dry, microcrystaline beads of carnauba wax.
