    Hair product residue, oils, and other debris can cause your flat iron to heat inconsistently so it doesn’t straighten your hair as well. Product buildup can also make it harder for your iron to heat up and damage its plates, which reduces its lifespan. [16]
  2. Watermark wikiHow to Clean a Flat Iron
    Hair product buildup and grime can catch in your hair as you use your flat iron, which can lead to breakage, split ends, and frizziness. If your flat iron isn’t working as well, you might go over your hair multiple times, which can cause heat damage. [17]
    • Always apply a heat protectant spray onto your hair before straightening it or using other hot tools. This helps reduce heat damage.
  3. Watermark wikiHow to Clean a Flat Iron
    When you use a flat iron coated with product buildup and oils, the debris tends to stick to your hair. This can cause your hair to look limp, greasy, and dull. [18]
    • After using a flat iron, your hair should look shiny, healthy, and smooth.

    After using your flat iron, turn it off, unplug it, and let it cool all the way down. Then, wrap up the cord and keep the iron in a spot that stays cool and isn’t exposed to moisture and other products, like a drawer or cabinet. [19]
    • Alternatively, store your flat iron in a heat-resistant bag or pouch .
    • Excess heat and moisture can damage your flat iron and limit its lifespan.

    Abrasive sponges and other cleaning tools can scratch your flat iron, causing it to work less effectively. Harsh chemicals like bleach can also erode and damage the iron’s plates. [20]
    • Stick to using soft materials, like microfiber cloths, and gentle solutions, like rubbing alcohol, when cleaning your flat iron.
  3. Watermark wikiHow to Clean a Flat Iron
    To keep your flat iron from getting coated with hair products and oils, limit how many you use before you straighten your hair. If possible, apply hair spray, styling creams, and other products once your hair is straight.
    • Tip : Do apply a heat protectant spray on your hair before using your flat iron (and other hot tools). Heat can damage your hair and make it look dull, which the protectant helps minimize.

    If the residue won’t come off your flat iron, no matter how hard you scrub, it’s likely time to get a new tool. Likewise, a flat iron that continues to smoke or smell after you clean it is a sign to replace it with a new one.
