Is it a good idea to clean Hoya Super HMC multicoated UV filter with alcohol napkin (specialy made for optic cleaning)? I have been cleaning my lenses with those, and never have problems. How about multicoated filters?

Peter,

I don't know.  I have a Hoya multi-coted filter (not sure it's the same series) and I use those lens cleaning fluid kits in it.  Wasn't I supposed to?  When I purchased the camera, lenses and filters at Calumet in London, I also bought the kit, so I would have expected them saying something if it wasn't adequate.  It didn't occur to me it might not be.

Regards,
Adelaide
