Liquid cleaners, NEVER applied directly to a lens, but

only to a clean tissue, "Q-Tip", etc., if without silicone or

grit, will not hurt lenses, and serve to lubricate the

surface while you clean. Finish with breath directed upward,

with the fog removed with clean tissue, etc.

No need to remove a good clean filter when shooting most

things - there is no observable effect on the image unless

bright, small light sources are in front of the lens,

especially with dark surroundings...
