Be Careful.......
I have been playing with Cortland Linen wraps for 6 decades.......IMO......do not put any wax or cleaning material on the Cortland Linen......at most, maybe a damp cloth rubbed in the same direction as the wrap ....dry rub vigorously thereafter and burnish the wrap with smooth round glass afterwards.....and periodically burnish the wrap with glass burnishing as needed .I speak from actual experience successfully caring for Cortland Linen wraps and if I could have found some #12, it would be on all my cues.......Remember Cortland #9 is a fishing line, i.e., dampness won't hurt it, so treat with water which will help protect the hand woven flax strands and the glass burnishing restores smoothness and sheen......keep all chemicals away from this great wrap.....doesn't matter what the name on the label is or the specific chemical contents.....Just remember this is a fishing line spun onto your cue......stick with water like I have and you'll never go wrong.
