Whether using binoculars, spotting scopes or range finders or even trail cameras it is important to keep the lenses free of debris, which can cause scratching to the lens coatings. At a minimum, always carry a lens cloth made of microfiber in your pack and never use your shirt to clean the lens as some fabrics easily scratch lens. Microfiber makes lens cleaning safe and easy for light residue and smudges in the field. For heavier surface marks or stains left by dried water or other liquids, use a liquid lens cleaner designed specifically for the brand of optics you are using. A liquid lens cleaner paired with a microfiber cloth is safe for most of the lens coatings on optics these days.
Another great tool is the lens pen cleaning system. At one end is a non-liquid compound on a natural chamois tip that removes fingerprints and grit. The other end has a duster to remove loose dust and debris.
Tips to keep your optics in commission for years:
- Make it habitual to clean optics and store in the case when not in use
- Most common danger to binoculars while hunting is falling, this can be avoided with an inexpensive binocular harness or strap
- With optics it is better to spend a little more now with lens care products so that you do not spend a lot later to repair them.
