NELLIE’S ALL-NATURAL LAUNDRY SODA POWDER Made with only four ingredients, Laundry Soda is a highly concentrated formula that dissolves quickly in cold or hot water. This means your clothing won’t have a white residue left in the fabrics, that normally dulls your fabrics. When there is no residue left in your clothing, it also means your clothing is left soft and won’t irritate your skin. Nellie’s washing powder is hypoallergenic, as we do not use synthetic fragrance. Most importantly, it rinses completely clear, leaving your skin and the environment as spotless as your clothes~
