What do you use to clean windows?

Every company has their own solution that they use. One of the most common ingredients though, is Dawn Dish Soap. When I first started cleaning windows, that was the only thing we used... a hefty amount of Dawn mixed into a bucket of water does the trick. You can also add in different wetting agents, anti-static sprays, detergents, etc. Try to steer away from ammonia and vinegar because it will thin-out your solution making it harder to get a consistent glaze over the window. 

Why should I have my windows professionally cleaned?
