Got some very slight(only noticeable in sunlight) scratches on the mirror polished sides of my steelfish. Can you recommend a polish to take them out and restore the mirror finish? I'm assuming it must have a slight abrasive to it to remove the scratches, but fine enough to leave the mirror finish. Non abrasive polish like Flitz makes it bright and shiny, but leaves the very tiny surface scratches. I don't even know if it can be done by hand, but thought I would check. Thanks in advance!
