Product Description

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

Use one part Pre-Reduced Indigo, two parts Sodium Hydrosulfite, and four parts Soda Ash. Use 1 gallon (3.79L) of water for every teaspoon (5g) of dye.

For use as a color 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. Color removal works best at a rolling boil. Keep fabric moving for 10 to 20 minutes or until color has left as desired. Wash with mild detergent in cool water.

Note: not all dyes are fully susceptible to color 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.
