Whatever you do, never use vinegar or any other acid in an attempt to neutralize your chlorine bleach. It will destroy the hypochlorite that is the active ingredient of chlorine bleach, but only by turning it into much more caustic and dangerous chemicals, including hypochlorous acid, which is very damaging to textiles, and, if the pH gets low enough, deadly chlorine gas.
The problem with vinegar is that acids react with hypochlorite to form even more caustic and deadly chlorine gas. One should never mix acid with hypochlorite, and vinegar is an acid.
However, thiosulfate is not the only chemical that will safely and completely neutralize hypochlorite bleach. Both sodium metabisulfite (ProChem’s Anti-Chlor) and hydrogen peroxide (3% solution) are just as effective and safe as thiosulfate.
So, going to try this.! It has a great fashion sense (:
