I dont let anyone touch the glass, so finger prints arent a problem. Other then that, I have just been using a damp paper towel (water to damp it) to wipe off excess water drops and dust.

Try telling a 2 year old that he cannot touch the glass (or press his face as hard as he can against it!!)... though he has recently realized, after being told a million times, that he cannot bang on the glass!!
