I figure that I might as well post this here as well.
I use MEK (methyl ethyl ketone) at work. This stuff evaporates incredibly fast and cleans anything. I figured this would be great to use to clean a shaft. After using it one time I actually think it is far too harsh for wood as it left my shaft white.
So any of you guys that work with MEK don't even think of using it on a shaft. I will say that if it is super dirty and has a lot of wax build up on the shaft you should use it sparingly, but otherwise it is just too harsh.
*edit*
The reason not to use it is because of the oils in the wood already. MEK will strip all oil out of anything. If you have ever gotten that stuff on your hands you would know why as it would leave your hands dry as hell.....sometimes dry cracked and bleeding if you get enough on you for a period of time. Heck it will eat through latex gloves in a fairly short period of time

Great post -- haven't seen anyone bring up methyl ethyl ketone (MEK) in a while!
But MEK is Super Bad(TM) for laminated shafts. The glue used to hold the laminations together is especially vulnerable to a super solvent like MEK. You see what MEK does to plastics, right? No cured glue or epoxy -- short of the stuff they use at NASA to hold the heat shields in place on the shuttle -- is "MEK-proof".
And this would go for other super solvents like: Trichloroethylene (TCE), Acetone, Hexane, Ethyl Acetate, et al.
Alcohols, on the other hand, are considered medium-grade solvents, and won't harm the glue. (Usually, the glues that bond the laminates are either super-solvent-based; epoxies; or water-based that "cure" -- resulting in a material that only a super solvent will destroy.)
Remember when dealing with wood, the less water you use, the better. Denatured Alcohol (no water -- 100% alcohol) with a Magic Eraser is best. Denatured Alcohol is a fuel (used for alcohol stoves) as well as a solvent (for shellac), so it absolutely CANNOT have any water.
Rubbing Alcohol, on the other hand, varies with its water content:
- 50% water in the "dollar store" grade
- 30% water for the better grade in the pharmaceutical section of the grocery store (70% alcohol, 30% water)
- 9% water for the best "91% isopropyl alcohol" grade available in the pharmacy
The water content in these is what's to be worried about. Have you noticed when using one of these "rubbing alcohols" that the surface of the shaft subsequently has a "mossy" feel to it? That's the wood fibers that've swollen and curled-up due to absorbing the water in those rubbing alcohols. That's why you see the common "mandatory recommendation" to lightly sand the shaft after the rubbing alcohol / magic eraser treatment, to sand-down those curled-up/swollen wood fibers. You're actually removing wood, and leaving microscopic pits and channels that the wood fibers (you've now sanded off) have curled upwards from. These pits and channels are now places that attract and hold even more dirt than a smooth surface does.
It's best to use an anhydrous (no water) alcohol, like Denatured Alcohol, or the 100% IPA (isopropyl alcohol) used in circuit board cleaning.
I like to use these:
These are 100% IPA; they clean the shaft GREAT, and because the wipes are soaked in anhydrous (no water) isopropyl alcohol, do not leave a "mossy feel" on the shaft. No sanding required. And IPA is not dangerous to the glues used in laminated shafts, either. Plus, you can fit a handful of these in one of your cue case's pockets.
Hope this is helpful!

P.S.: be
very careful with MEK and other super solvents. Many of them are known carcinogens.
