What should I use to clean my glass windows?

We advise 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 mix your own with one part vinegar to ten parts water. Apply the mix to a soft, clean microfiber cloth or paper towel. We do not recommend glass cleaners that are ammonia- or alcohol-based because they could produce streaks or create a film that magnetizes moisture and dust.
