How to prolong the life of kerosene lighter

Turn down the flame to avoid high temperature.

Operation method: Open the bottom bin of lighter and take out the shell. Coat the colorless shell with vaseline or glycerin, and then insert the inner core of the lighter back into the shell. Oil will be squeezed out, and the oil can be evenly coated outside the joint between the movement and the shell. This will play a sealing role. It doesn't matter if you put a little more paint on the movement. The oiling place of the movement is also sealed, which will not affect the use and oiling. This will prolong the use.
