Car mirrors are easy to smudge and streak, especially if using improper cleaning techniques. Most people spray cleaning solution directly onto the car mirror, however, the cleaning solution can seep behind the silver coating and create black tarnish marks on the mirror. It is also common to wipe mirrors in circular motions to remove dust, dirt, and oils. However, this can spread those particles across the surface, redepositing residue from the cloth fibers and leaving behind cloudiness or streaks, making it harder to see clearly when using your rearview or side mirrors while driving.
For a safer, streak-free finish without harsh chemicals, Simple Green Ready-To-Use Glass Cleaner gets the job done without ammonia or harsh synthetic chemicals.
Tip: For best results, clean mirrors when the glass is cool to the touch and out of direct sunlight.
