1. An apparatus for producing an anti-freeze water solution in a vehicle comprising:
- extracting means including a desiccant for extracting water from an air stream,a first reservoir containing a concentrated anti-freeze liquid;
a heating means for heating of said desiccant to release water from the desiccant material; and
mixing means for mixing water extracted from the air stream with the concentrated anti-freeze liquid in a preselected ratio to yield an anti-freeze water solution.

Abstract
A method and apparatus are disclosed for self-replenishment of the solution contained within an automobile windshield washer system. Water is extracted from air such as through the use of a desiccant system in combination with an automobile air conditioning system. This water is combined with a stored concentrated anti-freeze liquid in a preselected ratio to produce a windshield washer solution having sufficient freezing point depression for use during winter weather conditions.
