Hi Joe,

The way I clean them is that I buy a lens cleaning kit from cameras stores. The kit typically come with a packet of papers, lens fluid and a little blower. The blower is inadequate, and I use a much bigger blower.

So, I blow anything off the front of the eyepiece with the big blower.

Then I put a drop of lens cleaning fluid on a paper sheet I've torn off, and gently dab it on the glass, and gently try move anything still there off with strokes of the wet paper.

Then I clean the glass with the dry part of the paper, where necessary folding the paper over a few times and using its edge to get into the corner edges of the glass.

While I've never had any problem with that fluid, I did buy a few bottles of Orion's eyepiece cleaning fluid, which worked just as well, but made me feel better.

A warning - I have written the above on some US forums, and some people expressed horror, claiming that I was removing the coatings. They insist they just use the weight of the paper to clean the glass - but I couldn't for the life of me see how they cleaned the edges.
Regards,
Renato
