Although the price is OK, I don't know if I want to have all that lovely toxic patina in my wort.

I'm at work so I don't have the article offhand, but I think he mentions something about this exact issue (copper, oxidation, what to avoid, etc). Can't recall if it's the most recent issue, or one of the back ordered issues I just got.
It might be worth a read before you buy this.

I soak copper in bleach quite often (does a bang-up job cleaning an MLT) and never have had a problem.

I never used salt when I used to clean pennies as a kid, and it always worked okay, but when I googled it a while back it seems every resource says to use salt. Apparently it produces hydrochloric acid, making it stronger than vinegar (acetic acid) alone... An explanation I found:Rhoobarb said:I always soak mine in white vinegar. Works great. Just curious, what does adding salt do?
Salt, or sodium chloride, combines with acetic acid from the vinegar to produce sodium acetate and hydrogen chloride. Hydrogen chloride is a strong acid and the combination of it and sodium acetate rapidly cleans the surface of the penny (most pennies are 95% copper, 3% zinc, and 2% tin on their surface).
