It's simple to clean the ceramic nail on your Cali Coil electric nail. Just turn up your Cali Coil to 1150 F for a maximum of 10 minutes. The coil will turn red, as you see in the photo. The residue on your ceramic nail will begin to burn and smoke off. In the photo, you can already see the white ceramic showing underneath the grime. This self-cleaning technique is advisable periodically, to keep your hits fresh and uncontaminated; the best part is you don't need any additional tools or liquids! Our Cali Coil electric nail is super user-friendly. Click here to buy one of these bad boys.
