How to clean Predator wood shafts?

What can I use to clean the shaft?

To clean your Predator shaft, use a towel slightly dampened with rubbing alcohol. After cleaning, use a leather burnisher or similar material to seal the shaft. Using a Carnuba wax may also help to seal the shaft and protect it from moisture. To avoid damage, do not sand the shaft; no abrasive is necessary.  Do not use any water-based cleaners on the shaft.

Can I use steam or drop of water to remove a small ding from the shaft?

No water can be used on the spliced shaft due to the nature of the glue used for the splices.  If water is used on the shaft, and the glue causes the seams to open, the shaft will not be covered under warranty.
