I just got two beautiful sets and they are covered in dust. You can sand a corner and wet it but it comes right back up and yellows the wood quite a bit. This is the orange poisonous sawdust I've been reading about right? When it takes shape as a guitar how do you finally get rid of that dust covering the surface? Blow it off as good as possible and then seal it? maybe the laquer brings out the red of the wood. This probably sounds silly. It's so gorgeous when you first sand it and it's red. So what's the trick?

thanks
