I wouldn't call the use of sandpaper "just wipes off"
Unfortunately it was an afterthought to try it when I had finished the blade. It wouldn't matter so much if I had started with the treatment, then the blackening could be dealt with over the normal course of restoration. There still is the fact that it did not remove the black rust from the pits and what effect the removal of carbon from the blade has. The amount is probably too small to matter but I still see it as a sort of "case softening"
