Paper towel, napkin, rag
Paper towel, napkin, cotton rag, I use whatever is handy. I'm not bashful about giving my shaft and tip a quick wipe with a very lightly dampened paper towel either. I find that after washing my hands the second or third paper towel I dry my hands on is perfect, just a hint of dampness that will catch dust but not wet the tip or shaft.
I will use the inside of my shirt tail or jeans if nothing else is available. It seems a bit lacking in class to use the pool room's carpet or even worse the joint between cushion and table bed as I have seen done.
