I'd suggest car polish, start with the finest to see if that works, then a step coarser if it doesn't, then coarse again until the scartches are removed, an then go finer again to give it the shine you're satisfied with. this method proved to be the best for me for removing scratches on straight razors without causing new or deeper ones than the initial - which also happened to me and i had to work my arse off to make it shine again...
