Here are the Scotchbrite pad ratings. You might try a white (1200-1500 grit) or a blue (1000) grit. Very carefully so as not to damage the sandblasting.

7445 - White pad, called Light Duty Cleansing - (1000) 1200-1500 grit

BUT.... If it was my gun, I would start even simpler. Consider trying a Mr. Clean white "Magic Eraser" and some plain water. I'll bet you have one under the kitchen sink already. It is so gentle, that I don't think it would do any damage to the finish. All said, I don't know the finish, so whatever you choose to do, do cautiously.
