Try boiling a solution of one cup white vinegar in five gallons of
water. Don't breath the vapors that are released.

Yes, let this be a lesson. It isn't necessary or even useful to use
sodium metabisulphite to sanitize beer brewing equipment. That practice
is apparently a carry-over from fruit and wine processing. Instead, use
a solution of tri-chlor or plain chlorine bleach as prescribed by the
better modern beer brewing books.
