I am hoping some of you can give me some advice.
I'm in Hawaii and have been having fun with my B+W UV and CPL Kasemann filters and my Lee and Hitech 4x6 filters.
Unfortunately, they all now have this film of salt and possibly fine sand on them.
How do I clean them with scratching them?
What I have with me: lots of micro fiber cloths, a brush, some Calumet wet and dry disposable wipes, and one lens pen.
I'm about to get on a plane for Kauai and am hoping you can tell me what to do or what I need to buy. I have three more days on the island and would like to get theses filters cleaned while I'm still here.
Thank you in advance!
