It depends on how deep it is, but we use a buffing wheel and cerium oxide with good results. Delta Kits sells these products, but they are available elsewhere as well. There are more expensive systems, but I don't feel that most work any better. Novus has a great scratch removal system that will take out even deep scratches, but you won't like the price much.

The Dermel tool and wheels that fit that tool just don't cut it in my opinion. The type of wheel you use, and the quality of the polishing compound is the key. There are many different grades and brands of cerium oxide, and they perform very differently.
