First you have to determine if your filters are acrylic (plastic) or glass. The safest solution is to use distilled water in a glass with one drop of kitchen detergent in the water. Then first rinse the filter with some clean distilled water to remove any dust from the surfaces. Then using a lint free cloth dab in the water (with the detergent drop) and wipe gently over the greasy area until you no longer see the fingerprints. Then rinse again with the clean distilled water and dab down with a dry lint free cloth to remove the remaining water. Don't use a kitchen towel or toilet paper on the exposed optical surfaces - as these are made from a cellulose (wood) base and can/will scratch the optical surfaces and/or the ND coatings. |
