What should I use to clean my glass windows?

We suggest that you should use a prepackaged vinegar-based cleaning solution or use an ammonia-free glass cleaner such as Windex or Sparkle. You can also mix 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 suggest using glass cleaners that are ammonia- or alcohol-based because they could form streaks or create a film that attracts moisture and dust.
