use the 95% denatured rubbing alchohal it works better than the 70%.
also if a shaft is really blue ive used a damp cloth with some oxi-clean rubbed into it and ran it up and down the shaft ,
then switched to a dry cloth. then used rubbing alch then the dry cloth again...
the oxi clean didnt damage anything....but im not sure it should be used all the time. just occasional if real blue.
then Burnish with whatever you like....
ive found that a 1/4 inch diameter white nylon rope coiled tightly around the shaft to where it fits your hand, and then frantically worked back and forth burnishes pretty good(the ropes weave gives it a texture that seems to burnish well)
