When you need a more thorough cleaning, wash the glasses with water and a small amount of mild soap. Carefully clean the lenses, frame, nose area, and temples.

Then rinse them with clean water to completely remove the soap and dry them with a clean, soft microfiber cloth. Do not store the glasses while they are still wet.

Do not use alcohol, solvents, household cleaning products, disinfectants, or harsh substances. These products may affect the lens coating, color, and finish of the frame.

Also avoid paper, rough-textured tissues, clothing, towels, dirty cloths, or abrasive materials. Even when they seem soft, they may contain particles that can scratch the lenses.

After using the glasses at the beach, carefully remove any sand residue before wiping the lenses. Sand can cause scratches when dragged across the surface.

Rinse the glasses with clean water, wash them with mild soap when necessary, and dry them completely with the microfiber cloth.

Keep the microfiber cloth clean and store it separately from objects that could transfer dust, sand, or grease. A dirty cloth can spread residue across the lenses and cause scratches.

When washing it, use a mild detergent and avoid fabric softeners or substances that could leave residue on the fabric. Let it dry completely before using it again.
