Compressed air is not adequate for anything which puts a film on the lens. A
cotton swab moistened but not dripping with window cleaner or pure alcohol
works fine. One should follow with a dry one to get any residue. This will
often cure the OP's problem.

Careful about the dry one - that can scratch. If it's pure alcohol,
there will be no residue after a couple of applications.
