Nellie's Laundry Nuggets combine the power of laundry soda with the convenience of biodegradable packaging. These items dissolve in hot or cold water providing the perfect amount of detergent and sparing the environment an excess of chemicals and phosphates. Drop a Laundry Nugget into the wash and your work is done. The hypoallergenic ingredients (which include a coconut derived surfactant wrapped in Mono-Sol film) will penetrate even the toughest stains. Nellie's suggest tossing the nugget into the drum of HE machines as the drawer may have very limited water therefore not allowing the nugget to fully dissolve. If the nuggets have hardened just roll them between your fingers to soften them up before use.
