ABSTRACT:
The area which is to be cleaned is intially subjected to a pulsating jet of a liquid which penetrates through the area and which liquid contains a cleaning agent. Thereafter the area is rinsed by a pulsating jet of water which also penetrates through the area. Accordingly, the dirt gets dissolved and a mechanical working of the respective area is achieved simultaneously with a rinsing away of the dirt. Immediately thereafter the now wet area is penetrated by a hot pressurized air jet such to achieve a driving away of the dampness and accordingly a complete drying. If necessary, above sequence is repeated. Due to the speedy drying a forming of rings at the cleaned area is prevented and it is immediately possible to see if a visually complete cleaning has been achieved.
