What should I use to clean my glass windows?

We recommend that you clean them with a prepackaged vinegar-based cleaning mix 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. Put the solution on a soft, clean microfiber cloth or paper towel. Do not use glass cleaners that are ammonia- or alcohol-based as they could leave streaks or create a film that attracts moisture and dust.
