It's colour-safe, septic-safe, and environmentally safe - good news for you, bad news for stains and odours. This chlorine-free Oxygen Whitener releases a boost of oxygen for bleaching stains, while cleaning and brightening colours and whites. In addition, just like all Nellie's products, it's biodegradable and hypoallergenic.
