Hydros ST

Hydros ST (Sodium Hydrosulphite 25%) is used as a reduction agent for stripping colour from fabric and as a dyeing auxiliary with Indigo and other Vat dyes.

Hydros ST is a stabilised form of Sodium Hydrosulphite (Dithionite) that is suitable for Indigo dye baths and dye stripper.

NOTE: Hydros ST is very unstable and does not have a long shelf life. To avoid disappointing results we recommend it be kept in a sealed container, in a cool dark cupboard.
