Abstract: A ramp rotatably attached to a base attached to a vehicle windshield has an inactive state in which a wear block attached to the arm which carries the wiper over the windshield passes over the ramp without touching the ramp. The ramp also has an active state in which the wear block rides up the ramp whereby the wiper is lifted off of the windshield so that the arm then returns the wiper to the windshield with a jolt causing debris to leave the wiper. A remotely locatable electromagnetic solenoid actuates the ramp into the active state and frees the ramp to be returned to the inactive state by a return spring. The solenoid is controllable from within the vehicle.
