How do you keep your eyepieces clean?

[BilliGoatsGruff]

I've noticed people seem to be on the fence about cleaning eyepieces, so I was wondering if anyone has tips on how they maintain theirs? There are probably dozens of different techniques and no doubt each person has a different opinion.

I only clean them when there is a noticeable smudge or finger mark on them. Got a bottle of blue stuff from Bintel, and just do it very gently from centre to outside with a q-tip.

Find an old plastic detergent bottle, thoroughly clean it hot water, and you have a blower to remove any dust off the lenses. Anything else like a smudge, use a plain tissue dampened with Isopropyl Alcohol, (from Bunnings in a spray bottle).
