By far the best way (pro shops do it this way) is to take the nock off and dip shaft in acetone for a minute or so and wipe clean. Prior to doing this scrape as much of the vane or feather off with a razor blade being careful not to nick the carbon shaft. Let me repeat.....remove the nock first......most important to remember this critical step.

I use this technique on redlines. cxls, and all aluminums.
