How to clean sunglasses?

The cleaning steps of sunglasses are as follows:

1. Use running water to rinse off the dust and sand particles on the surface of the lenses. Be careful not to use too strong water flow to avoid damaging the lenses.
2. Apply a cleaning agent to the surface of the lenses to remove oil stains. You can use specialized eyeglass cleaning agents, but also can use detergents such as dishwashing liquid or hand sanitizers.
3. Rinse off the cleaning agent and chemical components on the surface of the lenses with running water to ensure that the lenses are clean and bright, and do not use a cloth to wipe the lenses to avoid scratching the lenses.
4. Place the sunglasses in a specialized glasses case with a soft pad to avoid being scratched by hard objects or pressed for a long time.
5. If there is oil or hair stuck on the surface of the lenses, you can first use a brush or eyeglass cleaning agent to clean it, then rinse it with running water, and finally gently wipe it with a lens wipe to ensure that the lenses are clean and bright.
