Hair straightener brushes become dirty over time, that is why you need to clean them properly to use further. First, make sure that the straightener is turned off and unplugged. Dampen a soft cloth, rag, or paper towel with warm water. If there is hairspray or other product dried onto the iron, any ammonia- or alcohol-containing cleaner can break down hardened styling product on your straightener. With the wet cloth, wipe down the metal or ceramic plates, removing any dust or old hair. You can use damp ear sticks to get in the hard-to-reach places where dust may be hiding.
