Why We Love It: Nellie’s Dish Powder easily penetrates grease, food particles, and more, leaving every plate spotless. Plus, this biodegradable, septic-safe, and phosphate-free formula is plant-based and kind to the environment. Traditional liquid detergents are made of at least 50 percent water. Nellie's does not think selling you water and moving water around the planet is a very good idea. More cleaning power can be packed into a smaller space with a powder formula and this one packs a punch - you only need 1 tbsp per load in your dishwasher.
