Blades of hair clipper are cutting again

Blades of hair clipper again cut with aftershave.

Who of you does not know that, because you get a hair clipper and after a few times use, the blades move so slowly that the device no longer cuts but pulls. My attempts to clean the blades and with the oil to make the blades refill failed.

Tip: make the blades clean and make some of your aftershave on it and the device purrs again as in the beginning.
