Key Ingredients: Birch Oil, Lavender & Tea Tree Essential Oils, Plant-Based Surfactants, Acetic Acid Attirecare. It’s formulated with essential oils derived from birch, lavender and tea tree to neutralise odours and kill bacteria, while acetic acid settles the dye of the denim and maintains any natural wear. It smells great, too, thanks to the addition of sweet orange and ylang ylang oils.
