Homemade Borax-Free Laundry Detergent

When my first child was born I started thinking hard about the products we used for cleaning the house and the products we bought to eat. We switched to natural, organic, eco-friendly versions of everything. We cut back on processed food. We joined a subscription company for cleaning and bathing supplies. It started getting pricey and I started thinking about what we could do to cut back a little. Making this laundry detergent took about 5 minutes and the jar will last about 2 months for our family of four, doing between 7-10 loads a week. The materials for this batch cost about $5, we have tons left to make more. While the original recipe I used called for essential oil, I found that using a scented version of the castile soap was enough for us. If you like more scent, add a few drops of essential oil to bulk it up.


  • 1 ½ cups washing soda
