I make my own laundry detergent. i can list the amounts but its about $4 for a 5 gallon batch, as a concentrate. Some of the dry ingredients will last 4-5 batches. The soap aspects are something we already stock for several months but not years.

cool note for Off Grid clothes washer: 5 gallon bucket with lid. Cut hole in lid and insert a toilet plunger. Put in some clothes and water. Twirl/agitate with plunger. Hang dry.
