[QUOTE="David Hunter, post: 16698, member: 791"] I am a professional photographer. I use Carl Ziess lenses that cost $3500+ for 1 lens. I learned the hard way how to and how not to clean coated glass. 1. Use a strong bulb shaped blower to remove the dust etc. from the lens while holding the lens to be cleaned up side down. This can be bought at a camera store. Get a big one. 2. While holding the scope up side down use a natural hair brush to clean the remaining dust. These can be found at WalMart in the makeup department. I suggest getting this late at night so your friends wont catch you shopping in the makeup department. 3. Use the blower again. 4. I do not suggest lens tissue it is too ruff on the coatings, and it leaves little fibers. Get an old 100% cotton tee-shirt that has been washed about 50 times. The 50 or so washings will make the cotton soft. Wash the tee-shirt again with NO detergent in hot water to remove any detergents that were left from the last washing. Cut it into pieces about 5"x5" and store in a zip lock bag. Do not use the under arm section of the tee-shirt, it may have deodorant imbedded in the fabric. 4. Use your breath, blowing on the lens making a haaaaa sound to fog the lens. This will get it wet (fog). It’s OK if you have been eating onions the scope won't care. Use lens cleaners ONLY if the lens is EXTREMELY dirty. I suggest never using lens cleaners because they are destructive on the lenses coatings. Pharmaceutical grade acetone may also be used but, I wouldn't make a regular habit of it either. 5. After the lens is fogged with your breath, gently clean with the piece of tee-shirt using circular motions starting in the middle and working your way to the edge holding up side down. Remember the key word here is gently. 6. Repeat the last 2 steps as many times as needed to get the lens clean. [/QUOTE]
