Cleaning Hoya CPL
Apologies if this has previously been covered here: I had a look first, but many posts).
I would appreciate some advice on cleaning a Hoya Pro DMC polarizer.
Nothing I have tried works. Hoya suggest lens tissue with a spot of lens fluid. Doesn't work on mine. I've tried a clean microfibre cloth with "huff". Doesn't work on mine. A very soft, clean, dry spectacles cloth. Result ditto. The lens has a fine oily smear which simply won't go and just moves around, spreading a bigger mess over the filter. (On the subject of microfibre cloths, I also find that cleaning my LCD on my Fuji X100 with (a clean) one is OK as long as I'm not tempted to "huff" on it, but makes an unholy mess of it if I do).
