    Wash them with hand- or dishsoap and rinse.

    Try using a sharp blow to get the droplets off the glass, this may or may not work well depending on the coating.

    Dry the frame with your towel

      Cold water and dish soap is the way to go. Hot water runs the risk of delaminating the coating layer, and hand soap tends to have moisturizers that will stick to the lens. Microfibers are too abrasive, and don’t adequately lift debris away from the lens. Just lather a drop of soap to cut the oils, then rinse. If your oleophobic coating is still good and water slicks off the lens, you can even turn the faucet low and just run a trickle across the lens to dry them. So you literally never need to touch the lens with a towel or microfiber cloth.

      If you only ever use soap and cold water, your oleophobic coating will last for literal years. I’ve had my current pair for almost two years now, with no scratches and my oleophobic coating is still just fine. Lens cleaners, glass cleaners, etc all strip that coating away. And microfibers are bad about causing tiny scratches that build up over time, since they drag dust and debris across the lens as you wipe them. In contrast, water gently carries dust and debris away without scratching, then the soap removes the oily fingerprints and smudges without damaging the coating.

      Skip the sharp blow and use a microfiber. You can get them in packs of like a million from Costco and they work way better than anything else.

        Skip the microfiber cloths and use a sharp blow. They come for free and are guaranteed 100% free of grease. You will never have to clean your glasses twice because your cloth caused a new smear.

          Every time I’ve ever tried it I get a droplet of water stuck in the crevice where the lens meets the frame and have to go get a towel anyway.
