I've been looking at differant opinions on google on how to clean eyepeices but they vairy so much. Some people say use a q-tip and alcohal, others say using a microfiber cloth and gently rub the lense, some say to buy a thing called a Lenspen.

My finderscope and 9mm EP have eyelash marks on them. How would i go about cleaning them ? I have a microfiber cloth that i have used to clean eyeglass's with would that work ?

As you found out, there are different methods. The main issue is to make sure you do not scratch the eyepiece.

I use the q tip method. Make sure they are sterile cotton q tips, and not a cheap knock off that is made of something else like nylon.

I mix alcohol and distilled water, roughly 50-50. The alcohol evaporates quickly to help dry the eyepiece.

i use a blower bulb (available in camera supply stores) first to remove any dust.

I dampen the q tip and move it in a circular motion. I do not apply pressure, and frequently change the q tip for a clean one. I use several for each eyepiece, and go through a lot of q tips.

I do not use a lens pen because I ruined an eyepiece with one once. There are other people that swear by them and love them. So make your own decision.

Not to hijack or anything, but does this also apply to camera lenses as well?

I use LensPens after I blow off any contamination. It is great for removing non-abrasive contamination

When cleaning a lens only wet the cotton, never the lens itself. If any liquid gets down to the cemented elements they can separate and the lens ruined. Only wet the cotton enough to do the job without the fluid running across the lens.
