To keep your flat iron clean and working properly, start by spraying rubbing alcohol onto the plates. Allow the alcohol to sit for 2-5 minutes so the product residue can melt and break down. After that, use a soft, damp cloth to gently wipe away all the residue. When you're done, let the flat iron dry and you can use it as usual. Cleaning your flat iron regularly will help keep it in good condition and allow you to get the styling results you want.
