Leaving hairspray on a curling iron can damage your hair and the curling iron. For the curling iron to work well, it must be cleaned regularly. To clean a curling iron, you'll need a washcloth, rubbing alcohol or baking soda and water, and possibly professional curling iron cleaner.Know More
Make sure the curling iron is cool
Unplug the curling iron from the wall and let it cool. Lightly tap the barrel after a few minutes to make sure it is not hot.
Clean the barrel of the curling iron with rubbing alcohol
Pour a small amount of rubbing alcohol onto a clean washcloth and wipe down the barrel of the iron.
Clean the barrel of the curling iron with baking soda and water
Another option is to use a paste consisting of baking soda and water. Apply the paste directly onto the barrel and wipe it away with a clean washcloth.
Repeat the cleaning process
Repeat the cleaning process if any hairspray remains on the curling iron. Use the same method, applying more pressure to the areas with built-up hairspray.
Clean the barrel of the curling iron with professional curling iron cleaner
If neither of the two cleaning solutions work, buy professional curling iron cleaner from a beauty supply store. Follow the directions given by the manufacturer to complete the cleaning process.
