Polishing machined brass

How would you go about taking freshly machined brass to mirror shine? I have gotten the machine marks out if this helps.

what kind of rouge. if you start out with a cutting rouge you can get out all the little marks even better then go to a non cutting or brightening rouge and you can literally make a mirror out of it.

I've never heard of the "blue" compound but the white and rusty red are regular items.

Polishing compounds are made from very specific products. The rusty red stuff is "jeweler's rouge" and is on the coarse to medium side of the polishing compounds. White indicates a very fine aluminium oxide polishing compound which is the next step after the rusty red "jeweler's rouge". The white compound is generally the one which delivers the best finish which is closest or meets the mirror like finish.

But keep in mind that with aluminium alloys that the hardness of the alloy determines the abilty to achieve a mirror like sheen. The lesser alloys simply will not respond to finer polishing. At some point you "hit the wall" and that's as smooth and mirror like as the metal will go. When you notice that the last step did not result in a shinier look then you "hit the wall" and there is simply no point in going any further.

In some cases I've found that this last level occurs with wet sanding with 1500 grit sandpaper when no further gain occured when trying to finish the metal using the rusty red jeweler's rouge compound. Yes, it can actually be THAT bad and a smooth grey "brushed finish" is the best that some alloys can give.
