What should I use to clean my glass windows?

We advise that you use a prepackaged vinegar-based cleaning mix or use an ammonia free glass cleaner such as Windex or Sparkle. Or you can make your own with one part vinegar to ten parts water. Apply the mix to a soft, clean microfiber cloth or paper towel. We do not suggest using glass cleaners that are ammonia- or alcohol-based because they could leave streaks or create a film that draws moisture and dust.
