Designed to use on filters for DSLRs and mirrorless cameras, video cameras and more, the LensPen FilterKlear easily removes fingerprints, dust and grease. The round, flat cleaning tip is perfect for use with on most filters, and a retractable brush makes it easy to sweep particles away. The non-liquid cleaning compound means better control while removing dust, and its designed to never dry out. Simply replace the cap after using the LensPen to ensure the surface of the cleaning tip is refreshed and ready for next use. Avoid using on wet or plastic surfaces, or on polarizing filters.
