Sodium hydrosulfite, also known as sodium dithionite or hydros, has a formula of Na2S2O4. It is a white crystalline powder and exists in both the anhydrous and dehydrated forms. Sodium hydrosulfite has a powerful reducing capacity and allows vat dyes to be reduced readily at room temperatures. It can also be used as antioxidants in hair treatment processes.
Sodium hydrosulfite is stable when dry, but will slowly be oxidized by air. Even with the absence of air, it will be deteriorated and hence it cannot be kept for long and has a comparatively shorter shelf life. When sodium hydrosulfite is wet and in the absence of oxygen, it is unstable and will be decomposed to sodium thiosulfate and sodium bisulfite.

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.
