🌿 HYDROS – FAST REDUCER FOR INDIGO & WOAD VATS
Also called sodium dithionite or thiox, Hydros strips oxygen from your dye bath so indigo or woad can bond to fibre. Ready for dipping in about an hour, but for best performance leave for 2 days.
• Quick—no long fermentation wait
• Consistent, high-purity powder for rapid vat activation
• Cost-effective alternative to spectralite
• Fine, free-flowing granules supplied in a resealable pouch
How to use (10 L vat)
Warm vat to ± 40 °C.
Sprinkle 25g Hydros over the surface (add powder to water, never water to powder).
Cover 60 min; liquor turns clear yellow-green with a copper sheen.
Stir gently, keep air out, dip fibre, oxidise, repeat for depth.
Best for: denim overdyes, shibori, tie-dye, skein or fabric vats, classroom demos.
Safety
Wear gloves & mask; store cool & dry away from acids, oxidisers and children. Dispose of spent vats responsibly.
Pair it with our Natural Indigo Powder Kit for a complete setup.
