reel the line on either the spinning reel or the baitcaster anyway you like, when the reel is full cut the line from the spool and put the rod in something that will hold it stationary, hold the line and take off walking about a 100 yds or so, drop the line and walk back to the rod/reel , hold the line in front of the reel with a damp washcloth with medium pressure and reel all the line back onto the reel. now watch the twist fly out of the end of the line when you get to the last 5-6 feet, all of the twist will be out of your line now, it takes literally less than one minute to do. i do this on all my reels with new or used line every night before i fish.

if you are on the lake and excessive twist starts to show up - cut the lure off the end of the line and let out 60, 70, 80 yds of line out behind the boat as you idle for about 1-2 minutes, stop the boats forward momentum so there is no excessive pressure on the line as you reel it in, you can simply hold the line between your fingers when doing it this way due to the fact that the lne is already wet, when you get to the last 20 feet of line hold the rod high out of the water and once again the twist should be out of the line.
