Home Depot, Lowe's and Walmart carry Kleanstrip kerosene heating fuel alternative, which is a 1-K kerosene refined to lower the sulfur content, thus improving air quality and extending wick life. Kleanstrip burns cleaner than 2-K kerosene and is suitable for all kerosene burning heaters, lamps and stoves
2-K kerosene has a sulphur content more than seven times that of 1-K, increasing sulfur dioxide emissions that cause more frequent wick cleaning and maintenance. Consult the manual to your kerosene equipment for proper service cycles. Never use diesel, jet "A" fuel, Number 1 or 2 fuel oil or gasoline. The use of any could result in fire or explosion.
