While handeling my 1.25" V johnson, I touched the surface with my finger briefly. What is the best procedure for cleaning the filter? Thank You...

Since I had the same problem (now I use one-way-nitril-gloves):

First, try using a clean micro-fiber cloth. If this doesn't do the job alone, there are special liquids for coated optics.
But always be careful and very gentle ;-)
