In my experience *dry* microfiber cloth works the best! However, not
all microfiber cloths are made the same! Many that call themselves
microfiber, ain't! A true microfiber cloth has an almost *** y
feeling to it when used on glass. It's worth while getting two so when
one is the wash the other one can be used.
Before that, I tried all sorts of liquids from various lens cleaning
liquids to *** and, yes, even Windex! Nevertheless, whatever the
liquid there always seem to be a residue. I always used lens paper
because all other paper can cause scratches.
I still managed to scratch the glass, though, but it was due to a
grain of sand which got caught in the paper. So before any cleaning
it's worth while using a blow brush to get rid of big particles first.
Finally, the best way to check if the scanner glass is clean is to
open the lid and scan "nothing" in a darkened room. As the light
passes under the empty glass look at it at a very shallow angle.
Actually, I get down so my eyes are parallel with the glass. It's
amazing what can be seen like that.
After the scan is done, examine it under maximum magnifications (e.g.
in Photoshop) after increasing the brightness until black turns to
light gray. Any glass imperfections, scratches, debris or streaks will
just jump at you!
For compulsive scanner cleaners it's truly a horror to look at! ;o)
