Cleansing Orange is NOT part of our 20-colour eggshell dye kit as it's not used to colour your eggshell. Instead it's used to help wash back some of the stronger colours to allow for new colours to "take" on the egg.
Do not add vinegar to this orange.
It's recommended to put the cleansing orange pysanka eggshell wash in a plastic container with lid to keep on hand and to make sure it looks different than the eggshell dyes. Washing back darker dyes will change the colour of this orange, as it will slowly get contaminated with the darker dyes. Because of this, you will want to replace this cleansing dye often.
