Why does it say washes out of clothes?
When rinsed immediately or laundered within a day, the colouring has been shown to come out of clothes without the need for stain remover.
Why this product over a competitor?
I don’t use citric acid, which as a powder can irritate skin and airways.
Our product is environmentally friendly. Other competitors use biodegradable glitter, which sounds appealing at first glance but will only degrade properly in the correct microorganism/composting environment. It is not meant to go down the drain into our water systems.
What are the ingredients?
