RainX is for exterior surface, right?You can also apply a treatment like Rain-x, or one of the glass cleaner wipes with anti-fog.
I cleaned mine throughly and applied rain-x with a micro-fiber towel last summer. Still keeping the windows clean and fog-free several months down the line, and it's been wicked cold here in the Midwest.
