I am THE worst at cleaning mirrors and windows! My husband said, “no! Please don’t!” whenever I came around with the “blue bottle.” I was known as “the Streaker!” until I found M-H’s amazing, streak-free, no-odor Glass Cleaner for cleaning everything from mirrors and windows to marble, chrome, brass (gold) finishes and more! It even spot-cleans! No other products are good at removing fingerprints, dog nose smudges or water splashes without cleaning the entire mirror or window, but somehow M-H’s Glass Cleaner spot-cleans! I’ve used this for 10 years, keep it in every bathroom, kitchen, laundry room and in my office where I have a glass desk! I will NEVER use anything else! I don’t know how M-H did it, but they created THE BEST glass/surface cleaner in the world! Buy it, you’ll be amazed!!!
