I live my life behind little rectangular windows. I have windows to peer through at computers, and a different set of windows for spying on the world at large. I am window man.

Today, my specs are blurry and I can’t get them clean. I’ve tried cleaning cloths, and I’ve tried rubbing them on my shirt. I’ve even tried pump-action spays that seem to do little more than make the surrounding area wet with their inaccurate aim, and smudge the stuff on the lenses around into new and interesting patterns. What is that stuff anyway? Does it have a name?

So today the world is smudgy for window man. Anyone got any top window-cleaning tips?
