Every now and then when I'm working on light coloured blanks such as oak or olive wood I notice that the grain seems dirty like it has been touched by someone with dirty fingerprints. This is particularly evident on blanks with cross grain rather than straight grained features. I then battle to remove the stain, sometimes having to go back to 120 grit and even then not being completely successful and removing the stain. I was working on some olivewood, sanded down to 600 it was all going fine and then I rubbed a bit of acetone on it to clear any residual dust, the grain became dirty in places and actually looked torn, to the eye it seemed that as though someone had gone over it with 80 grit sandpaper. I think I'm fairly careful when it comes to handling the blanks but maybe I need extra precautions on these sort of timbers, what do you think?
