A remote control method for a multi-functional surface cleaning and pre-treatment device and a multi-functional surface cleaning and pre-treatment apparatus by the remote control method are provided to allow a worker to perform a blasting process using grinding chips even in a remote place. A remote control method for a multi-functional surface cleaning and pre-treatment device includes a blasting process, a blasting and washing process, a surface dust cleaning process, a surface dust washing process, and a grinding chip filling process. In the blasting process, a third valve(85) for discharging air from a grinding chip reservoir tank(100) is cut off and a first valve(82) and a second valve(84) are opened to permit high pressure air from an air tank(81) to flow into the grinding chip reservoir tank along a pipe(83), when a start button of a grinding chip supply display of a remote controller is pressed. Sequentially, a fifth valve(86) is opened to permit grinding chips in the grinding chip reservoir tank to move along a flexible pipe(87) such that the grinding chips are sprayed through a nozzle(88). When a supply increase button of the remote controller is pressed, the gap of the fifth valve is expanded to increase the supply amount of grinding chips. When a supply decrease button of the remote controller is pressed, the gap of the fifth valve is reduced to decrease the supply amount of grinding chips. When a stop button is pressed, the fifth valve is closed and the second and first valves are closed simultaneously with the opening of the third valve to stop supply of grinding chips and discharge air pressure from the grinding chip reservoir tank.
