Probably a stupid question, but here goes....
Is there any EASY way to tell if your windows are truly clean, and streak free? It seems like whenever I clean my windows and I think I'm done, if I look at them in just the right light, I'll find streaks, smears, etc. It's almost like trying to find wax you need to remove. You have to have the right lighting. But, for windows, it's even more difficult, or at least I think it is.
Is there anything I can use to EASILY tell if they're really clean? A special kind of light (UV?), maybe?
