Sodium Hydrosulfite is an effective reducing agent and works in the indigo vat to remove excess oxygen and prepare it for dipping. Sodium hydrosulfite can be used in a cool indigo vat, minimizing the need to heat your vat in order to hasten reduction.  It can also be used as a color remover to discharge colors from dyed fibers. Instructions included. Ground shipping in the continental US only which takes 7-14 days.  Cannot be shipped overseas.  It is a fine, granulated powder that dissolves easily in water.

  • 250 g of Sodium Hydrosulfite is enough for approximately 8-12 indigo vats.
