    Sodium Hydrosulfite “Hydro”

    Sodium Hydrosulfite is a universal reducing agent that is used for indigo dyeing.
    It is also used as a non-aggressive alternative to bleach for removing colour from dyed fabrics and for whitening antique textiles.

    1 lb/0.45 kg (Item CHM1025)

    For use with Jacquard’s Pre-reduced Indigo: use 1 part indigo dye : 2 parts Sodium Hydrosulfite : 4 parts Soda Ash. (Use 1 gal/3.79 L of water for every 5 grams of dye.)

    For use as a colour remover: use in equal parts with Soda Ash (1:1) at 3-5% by dry weight of fabric.
    Heat to 185°F/85°C, add fabric and continue heating.
    Colour removal works best at a rolling boil. Keep fabric moving for 10 to 20 minutes or until colour has left as desired.
    Wash with mild detergent in cool water.

    Note: not all dyes are fully susceptible to colour removal.

    Results may vary. Test first when possible.

    CAUTION: Harmful if swallowed.
    Give water or milk if swallowed and call a physician.
    Avoid contact with eyes.
    Keep out of reach of children.
    Do not expose to excessive heat.
