How to Clean Optics

Looking for the best methods to keep your binoculars, spotting scopes, rifle scopes, and rangefinders in top shape so they can perform their best? We've put together a complete guide to proper cleaning techniques so your optics will best carry out the task at hand when they're called upon.  

Exposing your binocular, spotting scope, rifle scope, or rangefinder to dust, dirt, and debris can hinder optical quality. So, regularly cleaning your optics are important to maintaining optical performance.

Ocular and Objective Lenses: start by using pressurized air to carefully remove any large particles and debris. For any fine debris that may remain, a LensPen or an optics brush can be used to brush away loose material. To remove smudges and oils that may have come in contact with the lenses, spray them with a small amount of optical cleaning fluid. Wipe down the lenses using a microfiber cleaning cloth and remove all fluid. For stubborn oils, a mild dish soap can be used using the same process.

Note: harsh cotton, facial tissues, or t-shirts should never be used since it can damage the lenses.
Ocular Eyecups: to eliminate debris from the eyecups and to further access the ocular assembly, twist the eyecups counter-clockwise and remove them from the binocular - this allows for a more detailed cleaning. Rinse the eyecup in running water for a thorough cleaning, then allow to air dry before replacing. 

Optic Housing: further cleaning may be necessary to maintain overall performance of the optic. Spray pressurized air into all hinges, seams, and mechanical components to remove grit and debris from the housing. Additionally, a microfiber cleaning cloth can used to wipe down all exterior components (e.g., rubber armor, anodized aluminum, etc.). A mild soap can also be used for those tough to remove stains and blemishes.  
For an all-in-one cleaning kit, check out the Maven Lens Cleaning Kit - it  includes a microfiber cleaning cloth, a lens cleaning pen with anti-static brush/chamois cleaning pad, and a 1 oz bottle of lens cleaner, all packaged together in a packable ballistic nylon case and is the perfect assortment to keep your lenses performing flawlessly.
