Well i work for a company that speacialises in alloy truck bodys, trays.
Ever woundered how they get it to look so good without having it highly polished?
Ive done this exercise on the second hand Procuirct 304 that my mate Roostmaster gave me because my "BRAND NEW" DEP wouldnt fit & looked like a gun on a battle ship.
OK 1 silencer after mods made to the mounts.....the welding process managed to curl up the sticker/decal, but amazingly the adhesive stayed put...at this stage it had been wire brushed & every other thing i could try to clean it had failed.....red Aussie dirt is a bugger to remove.
the glue was removed with some thiners & scotch brite pad.(this took longer then polishing it)

OK... the next step was to drop it into a acid sollution thats mild enough to work with without gloves...its like alloy mag whell cleaner...you dont have to do this but it makes it alot easier to polish when the time comes. It fizzes up as you can see, rinse thoroughly.

the bonous was it cleaned the inside...i hadnt given it much thought but it was a gift from this process.

As you can see 1 very clean but dull/satin finished alloy silencer, another suprise is it removed the rust on the rivets & the stainless steel tip came up like new.

Now the polishing bit....all you need is some OOO steel wool & comercial hand cleaner/soap, this hand cleaner "MUST NOT BE OF THE GRIT KIND", you know the sandy stuff, only use the soap type....now simply scup in a continal direction not in a swirling or circular motion as this will leave swirl marcks on your parts & you will be very suprised when you've rinsed it of with the hose.

Compare the stainless steel tip with the stainless steel inlet on the reasembled silencer... a bit of a differance hey.
