Good black polishing cloth with ridges for glasses and sunglasses

To clean your glasses and sunglasses, we strongly recommend that you clean them with a cleaning cloth like this one.

It is produced for this very purpose.

If you clean your sunglasses or glasses in your clothes, with paper or other things, you will most likely get scratches in the lenses.
That's why it makes sense to have a cleaning cloth on hand when your glasses have become cloudy.
