Gene, if you're sure the lines are solid you can blow string
thru them with your air gun then as the guys suggest, soak the
insides with alky and pull your twine back and forth in a
scrubbing motion. Somethin' like drying your butt with the bath
towel. That should scrub any cobs loose and help to loosen any
gummy buildup that may have accumulated. I then blow the lines
dry. I do this also with new lines that I've make up, as it
only takes a few minutes and assures that they're pristine
inside.
