How do you keep a lens clean?

Make sure to first remove as much of the dirt and dust as possible with either a dry microfiber cloth or a soft-bristled brush. For any remaining substances, you can consider pairing a lens cleaner with a microfiber cloth and gently wiping the screen in small circular motions. Make sure that you work from the center outward when using any kind of cloth on the glass.
