Cleaning oil, dust, or dirt off lenses can be a common task. There are solutions available to keep the lens clean found in anti-glare coatings. Anti-glare coatings that include hydrophobic or oleophobic properties help repel dirt, dust, oil, and water.
Microfiber (silk) cleaning clothes or various lens cleaning solutions are available to clean your lenses. As well as blowing off or shaking off any excess dust. Warm water and mild dish soap are also commonly used to clean lenses. However, one should avoid using household cleaning products and paper towels since they may damage the coating on the lens.
