Allen's Naturally liquid laundry detergent requires only 1/4 oz for HE Machines or when washing Cloth Diapers. Allen's cleans clothes and cloth diapers thoroughly, yet is gentle on fabrics leaving virtually no residue or perfume that can irritate sensitive skin. One ounce leaves clothes clean, bright and fresh-scented. A one ounce pump fits the gallon size for easy dispensing that also contains a 1/4 oz. restrictor clip for HE washers.
