Soap and water.
It is what you do clean carbons or aluminums with.
Fine sandpaper or steelwool will take the surface of the shaft down for good adhersion,but.
I use denatured alcohol or acetone to take the resin off the shaft after,usually when the glue or paint is on there so bad ya can't get it all off,it helps break it down but,ya do not need to do anything on new shafts,but soap and water for fletchings....
I am not recommending anything but soap and water here for safety issues even after using the alcohol,I know it works on all shafts.
I also advise not touching the base of the fletchings.
If ya do,just see if it adheres,if it don't you gotta strip and start all over again.
Quickspins are expensive,don't touch em.
