Have to do in the hobby with very sensitive optics (telescope, eyepieces, SLR) and did not want to go off with a cloth on the lens because of the risk of scratches is too big and always dust on the lens remains. The best way to clean a lens is, not to let them only be dirty. But go in rumhantieren not always and they put dust on their own. The fingerprint must now down times, because it would damage the lacquer coating of the lens and the field of view becomes cloudy. However, the appearance of paper is only the second choice. First, the dust must come down and this I use a blower (not with the mouth blisters ;-)). Should then still a dirt present (eg fingerprint) you can access to the optics paper, but never dry! Use it along with "Optical Wonder" cleaning liquid is sprayed onto the paper, not directly to the lens! Then you stroll the wet paper carefully on the dirt without pressure! If the pollution is rather wipe several times about it too persistent, but always use a fresh piece of paper, never twice! Then it does the job hervoragend! Little tip: use gloves because the fingers are always greasy. One more thing: have this paper ordered for an unattractive fingerprints on the lens of my refractor who wanted to be treated quickly. The seller moved it even from America! If it has to be fast going to the photo shop around the corner is meaningful. Have four weeks to wait!
