Believe it or not, the best solution to mirror streaks is a solution—a vinegar and water one, that is. Sure, store-bought cleaners may offer an all-in-one answer, but good marketing is no match for the cleaning power and cost-efficiency of this simple mixture. Plus, these cleansers tend to include more soap than is necessary, and more soap equals more streaks.
To avoid a cloudy surface, simply mix 1 cup of vinegar with 1 cup of distilled water in a spray bottle, give it a good shake, and you’ll have the perfect potion for tackling smears, streaks, and smudges. Apply your mirror-cleaning mixture directly to your microfiber cloth instead of the reflective surface—to prevent the liquid from accumulating in the corners, making its way underneath the mirror, and causing more damage—and zig-zag back and forth down the entire length of the glass.
