The unfortunately popular-and-hard-to-remove
silicon-based "cleaners" and silicone-impregnated
tissues/cloths will also leave a coat that fogs,
and holds dust... Great, huh? ;-)

Breathing (up!!!) on the lens surface
and working with the tissue/cotton-ball/swab
mostly when the lens is fogged with moisture
helps reduce static build-up when working,
and helps bleed-off static charge that was there.

No - it is the cheapest/best form of clear
single-coated protection I know, even though
the UV filtering is redundant (most multi-element
lenses pass very little ultraviolet that film
will record (though video could be more
sensitive to it, I suppose...). BTW, I often
recommend metal-rimmed single-coated Hoya
filters (well-made glass and rims [thin, sturdy],
easy to clean, cheaper than most) and do not
recommend Tiffen (thick rims can vignette, glass
tends to spontaneously fog [reason unknown, but
they do - either mounted on lenses, or stored
in various filter cases]).

I would avoid glass contact if possible - a strong
air blast from a large hand-syringe takes care of
most dust, a touch with a tissue edge or cotton swab
while blowing takes care of stubborn dust (when the
glass surface is otherwise clean). I reserve wiping
(with fluids) for when there is a smudge, surface
spot, etc. (see my first post above for the gorey
details...;-).
Maybe, just maybe, with all this your tupee will
stay planted when raising the lens abobe your head...!
;-), ;-), ;-)
