Abstract
Abstract A solvent-evaporation type of deodorant is added to the windshield washer fluid reservoir of a motor vehicle. When the material is sprayed onto the windshield of the vehicle while the vehicle's air conditioning (heating, cooling or ventilating) system is running, the deodorant is drawn into the vehicle passenger compartment where it dissolves odor-causing particles and removes them.
