What should I use to clean my glass windows?

We suggest that you clean them with 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 recommend glass cleaners that are ammonia- or alcohol-based as they have a tendency to leave streaks or create a film that attracts moisture and dust.
