Clipper oil is applied to clipper and trimmer blades and movable parts after each cut to maintain their performance and prolong their lifespan.
The oil acts as a lubricant, reducing friction between the metal surfaces and preventing them from overheating and wearing down.
This helps to ensure that the tools continue to cut smoothly and efficiently, without causing discomfort to the person being trimmed or risking damage to the equipment.
