How do you get rid of smell on sunglasses?

To eliminate odors from sunglasses, start by gently cleaning them with a mixture of warm water and mild dish soap using a soft cloth or microfiber towel. Rinse thoroughly with clean water to remove any soap residue. If the smell persists, you can wipe the frames with a cloth dampened in a solution of equal parts water and white vinegar, then rinse again. Finally, let the sunglasses air dry completely before using them again.
