An eco friendly wash needn"t mean a dull wash. Let your whites shine again, thanks to the power of oxygen. Works really well with laundry wash balls. Add one heaped teaspoon to your wash to brighten your whites, or for tough stains, add two or three. Always check the washing instructions! Pure Oxygen Whitener can also be used as a pre-soak treatment. Add two heaped teaspoons to hot water and soak colours for 30 minutes. Whites can be soaked for up to six hours. Suitable for both colourfast items and whites. Ingredients: 55% Oxygen based ingredients, 45% Inorganic salts, 0.3% Essential oil.
