I like crumpled aluminium foil as an abrasive, because
(a) You can conform it to any surface profile
(b) it has an anti-corrosive effect on steel
(c) It has no grit particles (There will be small aluminium particles detached, but I THINK these are less likely to embed, and less likely to be damaging, than, say those in Scotchbrite, which are alleged to have wrecked a lot of newly rebuilt engines).
(d) It can be used wet or dry, and can be combined with abrasives such as toothpaste, valve grinding paste, or., I suppose, Brasso
(They don't, AFAIK, make Aluminium-O. Maybe too hard a sell in America)
(e) Its possible to "forage" it up from sweetie wrappers etc
Of course I'm not concerned with cosmetics (I mostly use it on exposed metal, most recently the end of my camshaft, in combination with silicone grease) and I dont know how it compares with the other treatments mentioned in that context, (with some of which it might be combined) but if I was I'd test it.
