Another thing you might want to try is just going over the glass again with cleaner. This sort of thing tends to happen to me when there's still vinyl gassing residue left on the glass, and a couple extra passes usually gets rid of it. The stuff can build up pretty well, and unless you regularly clean (every couple months for me) out the inside glass, it'll take a few runs to get it totally cleaned up. Also, try using newspaper instead of paper towels when wiping off the glass cleaner; it's less likely to streak and won't leave any lint.

happy cleaning.
