The Straightener is not waterproof. So please do not immerse the product in water. Water can get inside the brush and damage the parts.
Method 1:
You can unplug the brush and use a wet cloth and soap for cleaning. You can also use disinfecting wipes (it’s easy!).
Method 2:
Dip cotton swabs into a water bottle cap consisting of rubbing alcohol. Rub between the teeth of the straighter as needed.
Do not clean with chemicals or scrubs. Air dry or use a soft cloth or paper towel to absorb the moisture. Store in a dry area.
