A quick tip to clean your optics, binocular or camera. Instead of using lens cleaning cloths and risk scratching the lens by grinding grit around and around, use a small ball of Bostik Bluetack and just roll it around the lens. It will pick up all the dust and dirt without grinding it into the lens coating. Store the ball in a small clean container, ready for next use. A 35mm film container is ideal (if you can still find one).
No, it will not leave a smeary coating on your lens.
