1 Cup of Borax
1 Cup Washing Soda/Soda Ash
1 bar of soap like: Ivory (scented O.K.), Zote, Fels Naptha, or Castile of choice.
If avoiding Xenoestrogens use a non scented castile soap. I am now using kirk's castile fragrance free bar soap from http://www.drugstore.come
I washed a load of towels so far. They came out fresh smelling, clean and soft.
If you do not want to use Borax, just not use it in the recipe or replace the same amount with Baking Soda. You can try that with the Washing soda to, replace it with same amount of Baking soda. I am sure you will still get clean clothes. I have read recipes online that use only soap and Baking Soda, but for liquid laundry detergent.
