Machine polishing stainless steel

Hi All,

I have a stainless steel industrial storage container that I'd like to get looking nice again. It's got quite a few scratches / scuffs / est...

I know stainless is usually polished, but I'd prefer it have more of a mat finish when i'm done.

Can anyone recommend a good method for giving it a nice mat finish? I was thinking like a Scotch bright wheel or something like that?

Depending on the severity & depth of the scratching I would sand the surface until the scratches are gone and you have a uniform sanded appearance. Then progressively move to finer grits. Next would be Scotch Bright, giving it a scratched grain pattern. You can vary the pattern by the grit of the pad, how hard you press and the orientation of your strokes. A wheel can do the same thing depending on the wheel. If you use a cotton wheel and buffing rouge you could bring it up to almost a mirror finish if you had a lot of time to kill.

For an overall mat finish I think the fastest and easiest is some sort of media blasting but you'd still want to sand down the scratches or plan on more blasting time. The texture you get will depend on the media. Play sand gives a coarse texture while finer abrasives will give a smoother finish.
