Abstract
The invention relates to a method for washing a motor vehicle wind shield (10) using a washing device (1) comprising reservoirs (2, 3) of first and second fluids, a channel (5) connecting the reservoirs (2, 3) to orifices (15) for ejecting the fluids onto the wind shield, at least one pump (20) intended to circulate the fluids in the channel (5), and at least one wiper blade (30), characterized in that, when the channel contains the first fluid, the method comprises the following steps: a) activating the pump system (20) so as to cause the second fluid to circulate in the channel system (5) so as to purge the channel of the first fluid, and b) deactivating the pump system (20) when the second fluid reaches the orifices (15).
