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. You can also make your own with one part vinegar to ten parts water. Apply the solution 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 form streaks or create a film that draws moisture and dust.
