I just use a green Scotch Brite pad and some paper towels right after a smoke, while the glass is still warm. I wet the scotch brite pad in warm water and it takes very little effort to losen the residue on the window with a little scrubbing. A couple wipes with some paper towels and the job's done. The key is doing this while the residue is still fresh on every smoke. If you let the thing cool it gets much tougher. The green scotch brite pads don't scratch the glass if that is what anyone is wondering.
