SODA ASH DYE FIXATIVE
Soda ash (sodium carbonate) is used to raise the pH in the pre-soak before you dye your fabric, helping to fix the dyes to the fibres of the fabric. This is an essential step to ensure that your tie dye is colourfast and that the dyes are permanent, so PLEASE DO NOT SKIP THIS STEP!
The ratio for the soda ash dye fixer soaking solution is 1 cup of soda ash to 4 litres of water.
PLEASE NOTE: The maximum amount of soda ash that can be posted within one order is 4kg. Any orders including more than 4kg of soda ash will be posted with 4kg and automatically be refunded the difference.
