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.

Claims

1. A method for deodorizing a motor vehicle, said motor vehicle including:

a passenger compartment,

a windshield for said passenger compartment,

windshield wipers for cleaning said windshield,

a spray system for spraying a cleaning solvent onto said windshield, said spray system including a spray nozzle adapted to spray a solvent onto said windshield, a fluid reservoir for holding a solvent, and pump means for forcing solvent from said reservoir through said nozzle and onto said windshield for spreading across said windshield by said wipers,

an air conditioning system for said passenger compartment, said air conditioning system including an air intake generally adjacent the lower edge of said windshield, a fan for drawing air through said intake and into said passenger compartment, and outlet means for permitting a substantial quantity of air to escape said passenger compartment and said vehicle,

said method comprising a step of adding to said fluid reservoir and operative quantity of a solvent-evaporation type of deodorant and a step of activating said air conditioning system and said windshield spray system to draw sufficient of said solvent-evaporation deodorant into said passenger compartment to evaporate odorant particles in said passenger compartment and evacuate said particles through said outlet, said solvent-evaporation type of deodorant comprising as its primary active ingredient a three to five carbon alcohol and further comprising a masking agent for masking objectionable odors present in said passenger compartment, said reservoir also containing methanol and a detergent.

2. The method of claim 1 wherein said three to five carbon alcohol is present in said reservoir in a concentration of from ten percent to fifty percent by volume.

3. The method of claim 2 wherein said alcohol is dimethyl carbinol.
