Buy lighter fluid – NOT lighter fluid for a BBQ
Open the lid of the lighter and take out the metal insert.
Set aside the metal insert.
Turn the insert upside down – there should be a felt bottom that says “Lift to fill.”
Using a pen or anything pointy. Lodge a pointy end into the tiny hole and lift the felt backing.
Squeeze the lighter fluid can once into the loose cotton. Wait a couple of seconds, then squeeze the canister again into the cotton.
Close the felt protector.
Place the metal box back into the case.
Let the lighter sit and absorb the fluid for 1 minute or 2. While waiting, wash your hands if lighter fluid spilled on you.
