We dry all of our acrylamide gels on glass and usually water alone is
sufficient to clean it off.  However, when that fails, a 4N NaOH
solution with a paper towel (or sponge)always does the trick.

Obviously your situation is different with UV filter glass, so try it
in  a corner of the filter first.

Good Luck!
