I tried to wipe down my Hoya UV and Polariser filters today, but the more I wiped, the worse it got, and now the surface looks cloudy ....

I have the Super HMC Pro 1 UV and the Dual Coated Polariser - is it possible that I may have destroyed the coatings ?

I'm not sure about now, but years ago, you had to be pretty careful with lenses and filters to avoid damaging the coating. You would roll or fold a piece of soft lens-cleaning tissue and then put a drop of lens cleaning fluid on the end, and wipe the lens or filter gently from the center outward in a spiral pattern so any gunk would be pushed to the outside. I've heard that modern coatings are tougher than that, but in any case, more gentle-ness is better.

You might be able to use a mild soap and water on your filters--but be gentle and rinse them well.

In cleaning the lensuse a micorfiber cloth, and a lens cleaning fluid. Wiping the lens in a circular motion can using microfiber clothwith lens cleaning fluidcan remove finger prints in your lens. You can also use blower to blast off dust in your lens. Be sure to be gentle in handling your equipment in cleaning.

Thanks for the advice.

I tried some window cleaning fluid, and that seemed to work okay.

Perhaps it would be better if I bought the Carl Zeiss Cleaning Cloths, or the Nikon Lens Pen ?

Those cleaning cloths that were all the rage a couple of years ago (microfiber)are very good. But remember a dirty cloth on a lens can do a lot of damage

I'm not sure about filter coatings...but I know that "window cleaner" is a NO-NO for computer monitors and televisons that have anti-glare coatings...products like "Windex" will eat itright off!! Hoya's aren't exactly cheap either, I'd definitely avoid using ammonia-basedwindow cleaner onanythingthat hasthe word "coated" associated with it...especially at 100+ bucksa pop.

Just my humble opinion.

Found this after reading your post...

Did some further searching on this product and discovered itsapproved by NASA for use on the space shuttle...cool, eh?
