How Can Melted Plastic Be Removed From Metal?

Either cool the plastic until it becomes brittle enough to break off, or heat the plastic until it becomes malleable enough to be scraped off, to remove melted plastic from metal. Once the plastic has been taken off, it’s a good idea to wipe off the area with WD-40, nail polish remover, rubbing alcohol, or, in severe situations, fine steel wool or fine-toothed sandpaper.

Burning off melted plastic is not recommended since it emits hazardous gases. Simply store the metal in the freezer until the plastic becomes brittle if it has melted onto an oven rack or other small- to medium-sized metal object. The plastic can then be carefully scraped or broken off using a razor blade or a hammer.

Using a hair dryer to warm up the plastic before attempting to scrape it off with a razor blade is another efficient way to remove melted plastic off metal. Remove the plastic by running the iron over a piece of aluminium foil that has salt sprinkled on it if the metal in question is the heating plate of a garment iron. The salt will assist in dislodging the plastic from the metal and making removal simpler.
