What should I use to clean my glass windows?

We advise that you clean them with 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 produce streaks or create a film that attracts moisture and dust.
