Here are some tips to clean mirror effectively: First, gather your cleaning supplies. You’ll need a microfiber cloth or a soft lint-free cloth, a spray bottle filled with equal parts water and white vinegar or a commercial glass cleaner, and a squeegee (optional). Spray the cleaning solution onto the mirror or onto the cloth. Avoid spraying too much solution as it can cause streaks. Wipe the mirror with the cloth in a circular motion or from top to bottom. Use a squeegee to remove any excess cleaning solution or water, starting from the top and working your way down. If there are any stubborn spots or streaks, use a clean cloth or a cotton swab dipped in rubbing alcohol to gently rub the area. For the finishing touch, use a dry cloth to buff the mirror to a shine.
