Do you think this kind of dirt can be cleaned? I've looked up Descratch, but it seems to be only for large vertical/horizontal scratches, and RemoveDirt but I had no success with it. The script is quite complex so maybe it can be fine tuned to work on something like that I don't know. Those marks look too difficult to remove but I thought I might as well ask, since some plugins are really able to work small miracles :D
