Our original wicks will assure you that your kerosene heater will work at its maximum heating capacity expected from any made-in-Japan kerosene heater when you use clean 1K kerosene.

 

Best way to preserve your kerosene wick life. 
Once a week try to burn the wick somewhere outdoor but away from wind draft until the kerosene heater burns all the kerosene inside the heater kerosene tank. This self-cleaning method will keep your wick life longer.
