Hard Rock This hard water formula is perfect for those that struggle with the toughest of water types! Hard Rock Remix will blow you away! This bag will do at least 45 loads, though some may find it does even more! What's new about Remix? · Gentle for longevity. The new blends have a lower PH than other detergents on the market, which means that it’s even gentler on fabrics and diapers. · Safer for sensitive skin. Having undergone cosmetic testing, Rockin’ Green can be used on the most sensitive of skin types*. · Better cleaning power. Designed to deliver more cleaning power per scoop, many customers have found a 60 percent reduction in stains, and are able to reduce the amount of “rock the soaks” needed. * Testing was done on Rockin’ Green’s unscented soap called Bare Naked Babies
