What should I use to clean my glass windows?

We suggest that you clean them with a prepackaged vinegar-based cleaning mixture 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 because they could form streaks or create a film that magnetizes moisture and dust.
