What should I use to clean my glass windows?

We advise that you should use a prepackaged vinegar-based cleaning mixture 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. We do not recommend glass cleaners that are ammonia- or alcohol-based as they could leave streaks or create a film that draws moisture and dust.
