What should I use to clean my glass windows?

We suggest that you use a prepackaged vinegar-based cleaning solution 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. Do not use glass cleaners that are ammonia- or alcohol-based because they could leave streaks or create a film that attracts moisture and dust.
