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.
3M Scotch Brite Nylon Pads: 7445 - White pad, called Light Duty Cleansing - (1000) 1200-1500 grit 7448 - Light Grey, called Ultra Fine Hand - (600-800) 800 grit. 6448 - Green (?), called Light Duty Hand Pad - (600) 600 grit 7447 - Maroon pad, called General Purpose Hand - (320-400) 320 grit 6444 - Brown pad, called Extra Duty Hand - (280-320) 240 grit 7446 - Dark Grey pad, called Blending Pad (180-220) 150 grit 7440 - Tan pad, called Heavy Duty Hand Pad - (120-150) 60(?) Green Scotch Brite is available EVERYWHERE. It's 600 grit. Blue Scotch-Brite is considered to be about 1000 grit. (The value inside the parentheses is directly from 3M.) 3M Chart 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.
