Hi Terra,

Thank you for taking the time to send us your feedback. We are sorry to hear your latest experience wasn't a great one! Boulder Clean Glass + Surface Cleaner is a non-streaking formula, so we understand your frustration. There may be some alternative culprits responsible for the issue at hand. Let's review just to be certain!

• Don’t wash glass when it is extremely hot or cold: heat and rapid evaporation lead to streaks.
• Clean your glass with a soft microfiber cloth or a squeegee.
• Avoid paper towels: when used on glass, paper towels leave not only streaks, but linty ones at that.
• Use your cleaning solution in moderation. Using too much is more likely to cause streaking. If the cloth you’re using gets too wet, trade it out for a fresh one.
• When cleaning a vertical surface, start at the top and work your way down to the bottom, rubbing from multiple directions.
• Quickly and thoroughly dry the glass after cleaning.
• If there are still a couple of streaks or smudges left on the glass after thorough cleaning and drying, you may be able to buff them out with a clean, dry coffee filter or microfiber cloth.

Also, avoid using glass cleaners that are ammonia-based, especially if you have pets or children at home—they contain harsh fumes and toxic chemicals. While they may seem like they’d produce a more intense clean, in reality, they can leave streaks and even a thin film that attracts dust and moisture.
