First, brush off any remaining dust or grime with a brush, soap, and water. Next is the disinfection step. Soak it in 75% alcohol or other disinfectants for a few minutes. Of course, you can also try our sterilization box, which has four powerful UV bulbs inside that send clean light to the outside of the nail. Complete cleaning in just 6 minutes. Finally, take them out to dry, then preferably put them in a dedicated nail drill bits organizer storage bag to make sure they won't be attacked by other chemicals. Note: The ceramic head is not suitable for UV exposure as it may discolor the ceramic.
