When appliances are delivered, they normally come with a plastic film over the unit, including the trim. This film is meant to protect the appliance during shipping and delivery, and is supposed to be removed by the delivery personnel. If you recently received an appliance and have discovered that the film was not removed, don't worry. It is not difficult to get off, and it usually can be done in a couple of minutes.
Scrape up one corner of the plastic film with a razor blade. Be careful not to scratch the surface under the film.
Work the corner loose until you get enough to hold onto with your fingers. Pinch the corner plastic.
Slowly pull the film from the appliance so that it doesn't tear. Use the razor blade to loosen it when it seems to get stuck.
Wipe down the surface of the appliance and trim with ammonia to remove sticky residue that may be left behind.
