What should I use to clean my glass windows?

We recommend 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. Apply the solution to a soft, clean microfiber cloth or paper towel. We do not recommend glass cleaners that are ammonia- or alcohol-based as they have a tendency to leave streaks or create a film that magnetizes moisture and dust.
