Cotton cloth

Cotton swab

Camel hair brush

The exposed lens surface of an eyepiece should be dusted periodically with a camel hair brush because camel hair brushes are preferred for cleaning optical equipment like lenses due to their soft and fine bristles that are gentle on the delicate lens surface and help prevent scratching. Using cotton cloth or swab may leave lint or scratch the lens, while a microfiber cloth, although gentle, may not be as effective in removing dust particles from the lens surface compared to a camel hair brush.
