Once the shaft is clean, the best, most important advice I can give is:...................THE PLAYERS NEED TO KEEP THEIR HANDS CLEAN BEFORE USING THE STICK.
So many times I clean a shaft, be it wood or fiberglass coated, hand it to them on a league night, and they go from eating pizza or wings, etc. and just pick up the stick and shoot their match. Then 3 weeks later, they're complaining that 'the stick is sticky, what can they do about it'
Cleaning it works, but education of the players make it last longer, IMO.
