I use a blower in the first instance to get rid of any grit/dust. Then I used to use a drop of camera lens cleaning fluid, and lots of camera lens cleaning paper (comes in a little folder, use one piece to gently apply fluid and gently get rid of any grit, then use either the dry part of the paper or another paper for the final clean). One can fold the paper into little triangles to clean around the edge of the glass.
Later on, I bought the Orion cleaning kit which used their special fluid and slightly softer paper pads. I couldn't really see any difference between using the standard lens cleaning kit I bought in camera stores, and the one I bought from Orion - but I felt happier using the Orion stuff.
That said, I had some discussion with people on US forums who were adamant that when using the same kit, one doesn't press and clean, one just uses the paper's own weight and gently pull it across the eyepiece - else the multicoatings are damaged according to them. I never understood how much patience they must have had, nor how they could possibly have cleaned the edges properly. And I'm pretty sure one should be able to see some evidence of multicoatings being damaged using my method.
I've acquired several lens pens, but have never been game to use them - fearing the rubbing of faint grit into the glass.
Regards,
Renato
