Did you know using windex leaves wax on windows and mirrors? And overtime that "streak-free shine" becomes impossible to get because of the wax. A better option is to use this Streak-Free Homemade Glass Cleaner instead, great looking windows, no waxy build up. Plus it's all-natural, super easy to make, and a third of the cost.
Mirror Cleaner - 1 part white vinegar - 1 part 70% Isopropyl Alcohol (a.k.a. rubbing alcohol) - 1 part pure or distilled water Directions: Combine ingredients and spray on mirrors. Wipe clean with microfiber cloth or newspaper. Note: The smell of this cleaner is kind of strong. I really like to add a few drops of either lemon or orange essential oils.
