Make a streak-free homemade window cleaner with the following household ingredients: 1/4 cup white or apple cider vinegar, 1/4 cup of isopropyl rubbing alcohol, 1 tablespoon of corn starch, and 8 to 10 drops of an essential oil such as lemon, orange or lavender. Combine all of these items in a spray bottle, shake it well to mix the ingredients, and then spray the mixture onto a glass surface, and wipe it clean.
The corn starch is the ingredient in this mixture that prevents streaking. If a person has a corn allergy, substitute tapioca or arrowroot, as they offer the same anti-streaking properties as corn starch. Use a microfiber cloth to wipe the glass clean, as microfiber is very absorbent and also helps eliminate streaking. When making this homemade cleaner, be sure to shake the spray bottle well to mix the ingredients, or else the corn starch could clog the spray nozzle. Add food coloring to the mixture so it won't be confused with water, and label the bottle to prevent any confusion about the contents. Using a homemade toxin-free window cleaner helps keep the family healthy, costs less money than commercial cleaning solutions, and is safe for the environment.
