Define 'minor'? Like scuffs from whacking stuff? 'Cause I would answer that with 'something abrasive.'
Maybe try a clay bar first (technically not an abrasive, IIRC, but works like one), then move on to some kind of rubbing compound if needed.
A lot of 'scratch removal' products don't seem to be much more than cleaner wax, and they're not going to do anything if you're through the clear coat. First thing is to identify if you're trying to clean up YOUR paint, or clean OFF something that transferred. I've seen people say that they had 'black scuff marks' or something, only to look at it and see that their 'minor' issue was that the paint was entirely gone, with the plastic underneath exposed.
