I use soda ash to make laundry soap. I couldn't find it any where in my area. I found it on line at Soapsgoneby.com soaps Gone Buy,Ltd 1085 College Road Eldorado, Il 62930 1-888-858-soap. It runs $4.95 a box an it is made by arm & hammer. I love the stuff. Its used in a lot of home made products I make and use. Hope this helps

It's also known as washing soda and yes, it is available at Kroger (surely at Wal*Mart too) in the laundry products isle. Arm & Hammer is most common but there may be other brands too but I've never seen them.
