We sell Firefly Simply Pure all over the world to finicky folks that want the highest performing lamp oil available and we have been able to keep the price reasonable because of the demand. This fuel can be used indoors our outdoors. </p> <p>We suggest using the fuel in oil candles, table-top tiki torches, oil lamps and lanterns. Try it plain or purchase with citronella or eucalyptus oil to keep the bugs at bay. </p> <p>I'd like to give you some tips so that you can get the maximum performance from Firefly Liquid Paraffin Lamp Oil. IMPORTANT: You can get even the purist fuel to smoke if you use it improperly.</p> <p>1) Remove old residual fuel from the fuel reservoir before filling with Firefly Fuel. It doesn't need to dishwasher clean but you certainly don't want to mix fuels together. Mixing fuels will change their burning properties and may cause excessive smoke.</p> <p>2) Use a clean wick. The wick is the delivery vehicle for the fuel. If the wick is contaminated with old fuel or water, it will not perform properly.</p> <p>3) The wick should be as low as possible. This will reduce smoke, provide a more consistent flame and conserve fuel.</p> <p>Liquid Paraffin Lamp Oil will solidify at the freezing point of 32 degrees. It will turn to liquid again above 32 degrees without harm to the fuel.</p> <p>Here are other considerations that may be of interest. Our plastic bottles are recylable All Firefly Fuels use commercial-style bottles with childproof caps and there are NO inactive ingredients, such as colorants, which reduce purity. </p> <p>And, what about potential leakage? We electronically seal our bottles to prevent leakage and our packaging has been tested and approved to ensure the product gets to you in tip-top shape.</p><p>Always use in a well ventilated area and never leave your candle or lantern burning unattended.</>
