You would think that streak-free cleaning of windows glass and mirrors would be enough but for some reason, people insist on glass cleaners being blue. The mint scent was our idea. Soon, glass cleaners will have to be both blue and minty. Just remember who thought of it first. At method, we think "clean" should smell more like mint than ammonia. So go ahead, clean another window while you're at it. It's like giving your home a spa treatment.
