Abstract
A vehicle polishing method includes a first polishing step of moving a portal or gate-type travel frame travellable forwardly and backwardly in one of opposite travelling direction over a stationary vehicle to polish the body surface of the vehicle by rotary brush means mounted on the travel frame during such movement while applying a foamy primary treating agent containing an anionic surfactant onto the body surface by a primary treating agent applicator mounted on the travel frame, and a second polishing and rinsing step of moving the travel frame in the other travelling direction and polishing the body surface by the rotary brush means while applying an aqueous wax containing a cationic surfactant onto the body surface by an aqueous wax applicator, and ejecting fresh water onto the body surface by a rinsing unit mounted on the travel frame to wash away the excessive wax from the body surface. After termination of the first polishing step and before starting of the second polishing and rinsing step, the cationic surfactant-containing aqueous wax is applied to the rotary brush means for a predetermined period of time. The apparatus for carrying out such polishing method specifical…
