Recently, I found myself in a bit of a pickle. A mess of streaky windows with no Windex to be found. What to do? Google to the rescue. A few moments after my initial duress, I found the simple solution. Mix equal parts white vinegar and hot water with a splash of rubbing alcohol. Place concoction in a spray bottle and viola- a streak free shine!
Not only is this cleaner incredibly cheap, it is also non-toxic. Now that it is a cleaner you can feel good about!
