Christopher,

Hopefully, the scratches aren't too deep. These can be removed, but it 
takes a little elbow grease and some tools:

You'll need different grades of sandpaper and a buffing wheel. I like to 
start with 400grit and then go to 600, then 1200, sanding north/south 
and make sure you are keeping a very straight line with your technique. 
After you've gone through the last grade, then you buff east/west. This 
method will remove most scratches, provided they're not too deep.

I'll be interested in looking for other methods of doing this. The 
method I use is time consuming, and it's the only one I know that works.
