This web site:
'Antichlor - Wikipedia, the free encyclopedia'
(http://en.wikipedia.org/wiki/Antichlor)

says that sodium metabisulfite can be used as an antichlor. *Sodium
metabisulfite can be purchased in any beer and wine making shop. *It's
dissolved in water and used to sterilize the beer or wine making
equipement.

Sodium metabisufite is used to sterilize beer and wine making equipment
because the sulphur dioxide gas it releases will kill bacteria, but
isn't poisonous to us. *In fact, sodium metabisulfite is used as a food
additive, but I don't know how it's used in food.
