    Default Cleaning lenses with A/R coating?

    Sorry if this is a noob Q.

    How would one go about cleaning lenses with the anti-reflective coating? In the past on non-coated lenses, I have used 99% isopropyl alcohol on a cotton swab (Q-tip), with very very light pressure. Is this also OK for lenses with AR coating?

    Hi Greg

    You need some 'First Contact' polymer lens cleaner. You'll find it on Rob's (Stanwax) web site. First contact is an easy (and excellent) way of cleaning all the optics in your projector. It's not cheap, but a small bottle goes a hell of a long way and should last you years depending on use.

    Thhis subject has been debated many times before and if you do a search you'll turn up loads of useful info'.

    Cheers
