I. Aswell as washing the glass you have to clean it with a sharp blade which takes off all the little impurities on the surface that the sponge leaves on, otherwise when the film is applied you are left with little bits stuck under it and it looks dreadfull when its dried out. If you have any dirt or grit left on the edge of the film it will very slightly lift the film up where the dirt is, when the window is wound up or down the film will be caught by the rubber gasket and pull the film off regarless of wether you have cut the film back from the edge.
2. you cant get a flat piece of film onto a curved piece of glass especially on the back window. We use a hair heat gun to shrink the film to take up the curvature of the glass, so when you take off the backing sheet it is already to the right shape, which takes away any flutes appearing and stops the risk of creasing the film.
3. When pulling the backing sheet off the film, you have to spray the adhesive side because static electricity is created and if the adhesive isn't kept wet then every dust particle and bit of dirt in the air will then adhere itself to the adhesive and once that has happened it is hard to get the film clean.
Window films these days have moved on considerably over the last 10 years. Most window film adhesives dont react that well to washing up liquid as there is a chemical in them that after a while can turn the films milky in colour.
