How to fill a Zippo with lighter fluid?
open the lid, pull the lighter out of its casing, get the felt pad out of the way, pour some lighter fluid on the cotton, wait to let the cotton absorb it, and do it again once or twice (but don’t overfill),place the felt pad back, put the lighter in the casing(with the spark wheel pointing away from the lid), and wash your hands because there could be lighter fluid on your hands.
