Refilling lighters

[Zeede]

Yeah the jets eventually wear out.

I thought it was the spark element that usually went out.

My procedure is this:

1) Turn flame down to the lowest setting. My theory is this seals up the business end.
2) Turn the lighter upside down and purge it until there is no more hissing sound. This can take awhile.
3) Place them in the freezer for ten minutes.
4) Fill them back up. I do it twice for a few seconds each.
5) Allow them to warm back up to room temperature naturally, then adjust the flame back up a bit and test light.
