When trying to get the perfect ringlets, hairspray comes in handy, especially if you can spray it onto the hair while it's in the curling iron. The downside is that, over time, hairspray builds up on the curling iron, and then interferes with how future curls turn out. Clean your curling iron at first sight of hairspray buildup to keep it functioning properly.
Say Goodbye to Buildup
Start with a cool, unplugged curling iron. Wipe the barrel with a soft, water-dampened rag to remove as much hairspray residue as possible. Go over the barrel with a dry rag. Lift up the clamp on the curling iron and clean this area as well. The hairspray may come off with just water if it's not caked on too thick. For heavy hairspray buildup, put some rubbing alcohol on a cotton ball and wipe the barrel and inside the clamp to remove the hairspray, or make a paste of baking soda and water and rub gently with a rag. Baking soda is slightly abrasive, so wipe gently to avoid scratching the metal of the curling iron. Wipe the surface again with a water-dampened rag, then a dry rag to remove any residue.
