We wash our diapers in a three step process using all natural ingredients. We rely on mother nature to sanitize (the sun!), and vinegar to deodorize. We use a scent-free and a natural chemical only detergent we make ourselves. It works great! On the off chance there isn't a sunny day all week, we will use a conventional dryer to dry your diapers. When this happens, we will use a high temperature wash cycle to sanitize instead.
