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.
