What is the procedure should I ever need to remove the adhesive window film? Is it difficult to get rid of any residue on the glass?

In most cases it is very easy to remove SOLYX� or SimGlas� adhesive films. Peel away the film from one corner and pull the film from the glass. If any adhesive remains on the glass it can easily be removed with a spray of soapy water and a single edge razor blade. Blades cannot be used on plexiglass or polycarbonate sheets to remove film.
