Hello Steve, the only successful way I've found to sort it is literally strip down the rig and start again. Cast out and run the mainline through a wet towel under slight tension to remove the fluff, strip the rig off and reset.....Obviously unblocking the eyes on the rod if needed....
A pain in the rear I know but better than sodding up an expensive waggler rod etc..Repeat as necessary...I have at times set a couple of rods with the same rig/setup....Expensive, but needs must etc....
