You can make an inexpensive anti-fog glass spray to keep your bathroom mirrors and the inside of your car's windshield fog-free. This solution keeps condensation from collecting on these surfaces.

Steps:
1. Pour 2 ounces of white vinegar in a medium sized bowl.

2. Add 1 quart hot water.

3. Dip a clean, lint-free cloth into mixture.

4. Lightly wring out cloth.

5. Wipe mirrors and the inside of car windshields with cloth.

6. Allow to dry.

I have just used Rain-X anti-fog. IT works pretty well, but it is a b!tch to actually get it off the window without streaks.
