What should I use to clean my glass windows?

We recommend that you should use a prepackaged vinegar-based cleaning mix 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. 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 produce streaks or create a film that attracts moisture and dust.
