I've yet to try it, but I've not doubt it works.

I've made telescope mirrors, you grind a parabola into a glass disc, then
coat it with aluminium.  Shiny!

It's one of those things that's obvious in hindsight, but I wouldn't have
picked using chocolate as a polishing agent.  Toothpaste, yes.  I recently
saw a article doing the same with an aluminium satellite dish.

But still, spotting the potential in the wrong end of a coke can is pretty
good!
