I noticed these weird white marks on my fingerboard while at a concert. They're only vidible under lights, but most room lights make them visible as well. I'm not sure what's causing them but should I be concerned and take it to a repair shop?

The picture makes it seem like dots, but they're really more like unorganized lines. 


Thanks for for the help.

@cdennyb (take a look?)

Hopefully it is just rosin buildup on the fingerboard.   But I am just no expert.

Looks like some kind of grains to me. I think I need to see more pictures. My browser did something strange when I clicked on it. It kept on reloading the same image many times and caused Safari to crash. Might have been just a coinsodence but it might be better to post the picture here than to give us an external link in this case.

Ebony is inherently a "loose grain" dense wood, which at first thought sounds counter to the term dense wood. Although a heavy wood it has a porous surface structure unless properly scrapped as sanding does no good.

What I see are specks of normal dust embedded into the voids (microscopic in nature mostly) and accumulated into visible 'white spots'. If you carefully take a soft cloth like a microfiber one ( doesn't usually leave any lint behind) and apply some alcohol and clean the surface you can eliminate many of those from it.

Careful using alcohol as a drop on the varnish finish can and many times will leave a spot and touching it will ruin the finish as the alcohol acts like a solvent on it.

Not much else you can do. It does not affect the sound at all and I seriously doubt you can 'feel' it with your finger as it's played.
