What should I use to clean my glass windows?

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