Good lighters can cost quite a bit of money and, like any high-quality product, they're designed to pay for themselves by offering a long service life to their owner. In the past, refillable lighters were almost all liquid-fueled types. Today's refillables are just as often filled with butane. Cigar and pipe smokers, in particular, tend to gravitate toward these models as they lend no fuel taste to their tobacco products.
Liquid fuel lighters require more maintenance and cleaning that other types of refillables. While liquid fuel is reliable, will ignite in very high winds and is very inexpensive, even for the highest-end fuels, it does not burn as efficiently as butane. Therefore, it tends to leave behind traces of carbon and other impurities left behind when the lighter is lit. Cleaning this, conveniently enough, is best done with lighter fluid which is an excellent solvent. Lighter fluid may be added to the tip of a cotton swap and used to remove the black patches that tend to develop around the windscreen. Also pass the swab near the areas where the flint wheel and flint are set to ensure that these function correctly.
A butane lighter requires little cleaning. Butane burns very efficiently and leaves hardly any traces behind. Particularly where the torch lighters are concerned, there is almost never an occasion where one will find a black spot on their lighter. If there is, it can usually be removed by simply wiping it away with dry cotton or a cloth. If the jet area becomes obstructed, simply tap the lighter gently on a hard surface to dislodge the debris.
The flame jets are generally recessed a bit into the lighter. To clean them if they become obstructed, it's preferable to first attempt to tap out the obstruction by rapping the inverted lighter very softly on a hard surface. Make certain not to do this so hard that the finish becomes damaged. Chrome finishes and plastic finishes are very durable but tapping them too hard can result in dents and nicks. If the obstruction is still present after doing this, one may attempt to remove it"very carefully"with a bit of wire or a wooden toothpick. If something becomes deeply-lodged in the jet, it may be possible to blow it out by opening the fuel valve a bit without actually tripping the igniter device.
On an electric lighter, the obstruction can usually be removed by tapping or by pulling the obstruction out with a pair of tweezers or a straightened-out paperclip or other pick type device.
