Bananas Removes Stains

Today I decided to clean my windows. I tried using water, soap lather, even glass cleaners to remove the stains (almost 3 months old...))) from the glass window. It is the window in my kitchen and the hot air has made the stains more prominent. I was successful in my attempt but couldn't succeed fully.
I always eat one banana after my workout. So, I thought of trying my luck with bananas. I took a piece of it and applied it on the surface of glass. After 2 minutes, I used a clean white cotton cloth to remove the stains. To my surprise I've a clear surface with stains fully removed. WOW...Try this simple trick and keep your windows glossy
