What is safe to use to clean Calcutta polarized sunglasses?

To clean Calcutta polarized sunglasses, use a microfiber cloth to gently wipe the lenses, as it minimizes the risk of scratches. For more thorough cleaning, you can use a solution of mild dish soap mixed with warm water, applying it with the microfiber cloth. Avoid using paper towels, rough fabrics, or ammonia-based cleaners, as they can damage the lenses and coatings. Always rinse with clean water before drying to remove any residue.
