Why not use silver polish?

[fishtaco]

From the Perth mint web site,take note the use of the word "polished"in both proof and bullion sections

They don't polish the coins, educate yourself.

yes but they polish the planchets so best educate yourself before trying to teach others

Of course they do, (almost) everybody knows that.
