What should I use to clean my glass windows?

We recommend that you should use a prepackaged vinegar-based cleaning solution or use an ammonia free glass cleaner such as Windex or Sparkle. Or you can 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 leave streaks or create a film that magnetizes moisture and dust.
