Look for the edge of the protective film. This edge often will be aligned with the edge of the front face of the appliance. The edge also may have a tab designed for making removal easier.
Insert the tip of a plastic scraper or a credit card between the edge of the film and the stainless steel. Don't scratch the stainless steel, but simply use the plastic to wedge the film away from the stainless steel surface.
Grasp the section of the film that you raised off of the surface of the stainless steel.
Pull the section of film away from the stainless steel. Pull downward if you are starting at the top of the product. Pull upward if you are starting at the bottom of the product.
Spray the stainless steel with white vinegar and wipe it with a paper towel to remove any residue from the film.
