What should I use to clean my glass windows?

We suggest that you clean them with a prepackaged vinegar-based cleaning mixture or use an ammonia free glass cleaner such as Windex or Sparkle. You can also mix your own with one part vinegar to ten parts water. Put the solution on a soft, clean microfiber cloth or paper towel. We do not suggest using glass cleaners that are ammonia- or alcohol-based as they have a tendency to form streaks or create a film that draws moisture and dust.
