I've found that ROR or residual oil remover works very well and that the Zeiss stuff a lot of camera stores carry works pretty well. Every few years I will acquire some denatured alcohol from the hardware store in the paint department. Pour a little into a clean cup or small container and using a Q-tip that is just damp in alcohol swab the element lightly even into the edges by the retaining ring. Use the dry end of the swab to polish then finish with the usual cleaning fluid system. The alcohol gets up all the weird stuff that gets on the lens which isn't water soluble but then you need something to remove the traces of benzene that makes denatured alcohol denatured. If you are into the sin quo non of cleaning lenses then Edmund Scientific sells some stuff that removes everything but the coating. Last, if you travel to the UK they sell some stuff that works by coating the lens, letting it dry, then peeling it off with everything else on the lens. You don't see it in the US as it will destroy the plastic used on most mass market lenses sold. Don dorysrus@mindspring.com
