Wait. You mean you're supposed to CLEAN THEM????!!!!????
J/K. Though the panes of glass are a "pain" - no pun intended - in my house, at least, people usually put their hands on the wood part instead of the glass which I don't mind cleaning. When I had sliding glass doors, my kids were forever smudging them with sticky "kid hands" and they seemed impossible to keep clean.
To each their own. As my husband and I say, that's why they make so many flavors of ice cream!
