From Bryan Geyer at Really Right Stuff: Stop buying lens leaning tissue. Buy rolled absorbent cotton instead. It cleans the front element of your lens like a charm and leaves no esidue. I’ve gone a step further: I save and use the cotton from my supplement bottles. From Moose Peterson: Use Lens Clens #1 Coated Optics (Industrial Optical Cleaner) for cleaning all your equipment, including the front elements of all your lenses
I bought the pint bottle which will most likely last a lifetime as I clean my stuff less in a year than Moose does in an evening…I keep the 1-3/4 oz. refillable bottle in my vest with a few chunks of absorbent cotton. Be sure to use a blower brush to remove any sand, dirt, or grit before using the Lens Clens and the cotton. Use one wet chunk of cotton to clean the lens and then a dry one to polish the front element. (Moose cleans the surfaces of all his lenses and camera bodies and accessories as well as the front elements of his lenses with an old, soft, cotton t-shirt each night.)
