Taking care of your birding gear is an essential part of optical performance. Maintaining the cleanliness of your lenses is vital in regard to the clarity and performance of binoculars and spotting scopes. The first step is to remove dirt particles, since they can scratch the lenses. You can remove these particles by using an optical lens brush or by using a canned air duster to blow away dirt and sand before cleaning to prevent any damage to the lenses. Once you’ve removed any particles, breathe onto the lens surface to form a coat of condensation and wipe using a soft, moist lens-cleaning cloth. If there are any hard to remove dirt or sand particles, send the product to the manufacturer’s repair department for a professional cleaning so that the lenses are not damaged. It is recommended that the product be sent in every few years for cleaning and a quality control check to ensure perfect performance.
