Slowly..? :shrug:
You may have to work down to the black rouge, starting with something just a bit smoother than what you scratched it with.
I have some 20ga 304 2b finnish stainless hemispheres that have some scratches on the inside. I put them there by using a medium scotchbrite wheel on a 5" sander. I was trying to remove some raised marks I put there during electropolishing. Had some water marks that left deposits after electropolishing. Now I have deep scratches from the scotchbrite. I need a silky smooth surface before I re electropolish them. I tried a buffing wheel with black rouge. Its shinny but the scratches are still very noticable.
How do I get the scratches out without makeing more?

I tried a very fine scotchbrite wheel but it didn't take out the scratches from the medium wheel. And at $25 a wheel I don't wanna go back and get a fine. Not to mention they had none in stock.
What about 300 grit sandpaper on a da. Kinda hard to get in there maybe.

How about a flapwheel?
You might as well resign yourself to starting with a coarser grit and working your way back to the polishing stage. Its faster than trying to do it all with polishing equipment.
First you get good, then you get fast. Then grouchiness sets in.

I usually use a grade A6 3m Trizak belt on stainless steel to take out the minor scratches before buffing.
However for hard to reach spots I recomend using a Walter quickstep fine"blue" surface conditioning pad followed up with a Walter feltpad with emmery compound.
