Do I need to oil my blades?

It is strongly recommended that you keep your blades well lubricated at all times, even during storage between usage. Although Wahl Professional blades are protected from corrosion, they will eventually rust if not taken care of properly. It is suggested that you apply a liberal amount of oil occasionally during use and after the job is finished. Take the time to properly clean the dirt and hair from your blade and apply oil to the entire blade to prevent corrosion.
