$18.17 total. Take a stroll down any laundry detergent aisle in any store & look at the price tags. You'll soon figure out that making it at home with these simple, inexpensive ingredients is WAY more cost effective. Especially for the amount that it makes. The catch here is that you only use 2-3 Tablespoons per load, so you get alot more cleaning power in a lot less detergent.
It's so simple - mix all the powdered ingredients up in a large big, or empty trashcan. You'll find it's easier to mix them all up if you pour in a little of each at a time so they will be mixed up pretty well from the beginning. The only time consuming part (and it's not even that time consuming) is grating the 2 Zote bars. Just get a regular cheese grater & shred the soap up! I found it was easier to do if I cut them into fourths beforehand.
