If you have tried to clean your windows with plain vinegar and gotten streaks, there is a simple reason and an easy remedy.The recommendation for windows was almost always to clean them with nothing but vinegar and water. People by the thousands tried this, and many swore off cleaning with homemade products for good because the formula left streaks on their windows. The problem was that the commercial window cleaner used before the switch to vinegar left a very fine wax residue. The vinegar alone wasn’t enough to remove it, and the result was streaky windows.
Try this recipe, combine 2 cups of water, 1/4 cup of white distilled vinegar, and up to 1/2 teaspoon of liquid soap or detergent in a spray bottle. the windows would have been cleaned perfectly.

I never tried this but I heard from lot of people that it is good way to clean window. Like you I also believes in cleaning with natural products so that we can assure about its side effects. I used less water to cleaning windows and I like to clean it with clean paper and cloth piece.
