Cleaning ...
I clean mine before every tournament I play in (don't play league anymore), which amounts to about weekly.
If I go longer, I clean every 2-4 weeks.
I use 'Orange', a natural Kroger product. Cleans shaft and ferrule good.
Dry. Use 'Pledge' on a paper towel, and then carefully on shaft only.
My cuemaker told me to only use a Chemical cleaner, and only a Wood Polish on my shafts (has to be a Polish, not oil, conditioner, or other nomenclatures). [Saves money and works good, Slipstic may be good, but I will not spend $30 for it]
I might add I do not like a super slick shaft (makes me feel as my stroke is slipping). I like just a slight drag, not much, just barely noticeable.
