What should I use to clean my glass windows?

We advise that you should use a prepackaged vinegar-based cleaning solution 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 solution to a soft, clean microfiber cloth or paper towel. Do not use glass cleaners that are ammonia- or alcohol-based as they have a tendency to form streaks or create a film that attracts moisture and dust.
