1.) Peel off the film.
2.) Soak a rag in acetone or laquer thinner.
3.) Rub the window, thoroughly soaking the residue on the glass.
4.) Be carefull to NOT get the acetone/laquer thinner on painted surfaces. (this is why i suggest pouring the acetone/laquer thinner on a rag as opposed to spray it directly on the glass.)
5.) Scrape residue with razor blade. You may need to re-wet the residue to keep it moist ... if it stays moist, it softens up.
6. Clean glass with vinegar and water ... or Windex, once all residue is removed.
7. Open beer and admire your new glass.
