My search for a chemical free glass cleaner

I have used all kinds of glass cleaners-Windex which I detest because of the smell, Sprayway, & Kelsan. They're all chemicals. When you spray them on your bathroom mirror, some of it gets on whatever's on your counter & everything on it-toothbrush, etc. Do you really want remnants of Windex, etc. on your toothbrush which ends up in your mouth? I now use club soda. I have also used vinegar & water.
