The Action Camera Lens Cleaner from LENSPEN removes dust and fingerprints from GoPro, Sony and other action camera lenses. Use the lens cleaner’s retractable natural brush to remove any loose dust or dirt from the camera lens then twist the cap off the other end with the cleaning tip to remove any dirt, grease or fingerprints from the lens. LENSPEN products use a similar carbon compound found in printer’s ink, which make newspapers effective for cleaning windows and glass. The Action Camera Lens Cleaner is environmentally friendly and will provide 500 or more cleanings. There’s also no expiration date.
