Product Description Wahl Professional Animal Clipper Oil is recommended for use with all Wahl Professional Animal blades for regular maintenance and optimal performance. Wahl strongly encourages groomers and pet owners to oil and clean their blades before and after every use to ensure your clipper's blade achieves maximum performance. The clipper oil helps reduce friction and heat that may be produced during the clipping and trimming of your animal's coat. It also reduces the likelihood of the blades becoming dull and helps increase blade durability. Note: using any other lubricant on Wahl clippers may cause damage to your blades and clipper and may void your clipper's warranty.
