Hi littleMagnum.I have pulled out carbon inserts by heating the tip of a target tip.Use a small flame for about a couple of minutes.DONT over heat,start to pull straight out,if not loose try again.The chemicals are not the way to go,they will weken the shafts bonding gluesof the carbon shafts.I have done this many times on broken shafts,it WORKS,just be carefull,and go slow.PS.The target tip has to be inserted in the arrow when you do this.Good luck.pan
