"You get a smooth surface that will respond freely."
Yes, most of us assume that to be true. However part of me does not totally accept it, because:
1. Unless I am mistaken, some racing yachts go faster - less friction with the water - if the surface is actually microscopically rough. It is to do with "Boundary Layers", and turbulence.
2. Sharks, which need to be fast fro survival, have rough skin.
3. Likewise, golf balls have less friction with the air if they are not smooth, but dimpled.
4. Some speed skaters wear clothing that has rough stitching on the legs, in strange places, in order to go faster.
5. I have heard that some oboe players, either do or used to drag steel wool through their oboes to roughen the surface slighlty to improve the sound.
6. Some technicians line saxophone tone hole walls with rough sand-paper to improve the tone.
I would like a REAL expert in the acoustic design of clarinets, especially having formal knowledge of the fluid flow sciences and their relevance, to comment on this issue. I acknowldge that I have no formal expertise in this area.
I definitely clean out tone holes, if there is any build-up of material, ANY time I have a key removed, "overhaul" or not. However until I know definitely that polished walls are beneficial, I am hesitant to spend time polishing them.
An incidental possible advantage of non-polished walls is that condensed moisture tends to spread over the surface rather than bead. When moisture beads, it is more inclined to flow into tone holes, or sit there making bubbling noises during play.
