The steps for how to remove plastic from an iron are easy once you know how. Start by turning your iron onto the warm setting and allowing it to heat up. This will melt the plastic and leave it soft – and thus easier to remove. Next, use a spatula to scrape away the melted plastic from the surface of your iron. If you see any residue in the holes, use a set of tweezers to gently tease them out. Finally, iron an old scrap of fabric. This should be enough to remove all remaining traces of melted plastic from your iron.
