Rockin Green products simplify diaper care. The makers of Rockin Green products understand that not all water is alike so they designed three different kinds of cloth diaper soap. Rockin Green Soft Rock is designed to be used in soft water and Rockin Green Hard Rock is designed for getting diapers clean in hard water. They also make Rockin Green Classic Rock for those who don't have hard or soft water. Their wool balls for the dryer are made to cut down on the time it takes for your cloth diapers to dry. Keep your diapers smelling fresh until wash day with the Rockin Green Shake it Up! Pail Freshener.
