Perfectly Clean Window Glass

Using a microfiber cloth, wipe down your window or a paper towel before you start to clean. Make your own solution by mixing 1 part vinegar and 4 parts warm water in a spray bottle. Spray the mixture onto a microfiber cloth or, if it's a large window you can spray directly onto the window. Also, if you have access to newspaper it is very effective at cleaning glass without streaks. Viola!
