[OldRestorer]

You can Gojo the top and that usually gets rid of the scratches. Somehow it removes all the crud but puts that removed color into the scratched areas. If that does not look good enough you can always use scratch remover. I forget the name brand?? Comes in light and dark in a bottle..

For the chips where the veneer is gone there is not much you can do besides add veneer patches or just stain them to match and live with it as original wear and tear.
