octagon soap is an old fashion lye soap. you can leave the bar in water and still will not go soft on you. my familiy has used it for all kids of skin rashes such as poison ivy. even used it to soak baby diapers in.
our Meijer and walmart have fels at $1.29 a bar.. I wish we Zote around here... great smell and it is a cloth washing soap too. kinda citrusy lime smell.. But I love the fels smell too. my wash comes out really clean and fresh with the home made laundry soap.
