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.
