I've heard that a variety of chemicals collectively called "Antichlors"
are used to remove excess bleach from textiles and paper pulp after

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.




It will neutralize bleach.
In food, it means that it can be used in quantities sufficient to
sterilize but not cause toxic effects. This is usually a few ppm.
