What do you use and why?Thanks.
If necessary, lightly damp paper towel. Then, rub with a dry cloth, like old t shirt material. This assumes the cuemaker put a sanding sealer on it in the first place, and you have not sanded it.
Most of all though, build up your natural hand oils on the shaft, which seals it and smooths it over time.
Do your best to avoid voodoo like Magic Eraser and crap like that. They're not made for wood. Your hands are best for wood.
All the best,
