This recipe's baking soda and super washing soda neutralize and eliminate odor instead of masking odor like store-bought laundry soap.

It may seem like the initial start-up cost is about the same as purchasing a bottle of store-bought laundry detergent but keep in mind one box of Borax, washing soda, and baking soda will make multiple batches of homemade laundry soap. This recipe makes six cups of laundry soap and calls for three tablespoons per load that's approximately 70 loads of laundry per batch.

Homemade laundry soap has a very light scent. If you like strongly scented soap you can add ½ cup of Purex Crystals to this recipe. This is still saving money because one bottle of Purex will scent about six batches of laundry soap. Keep in mind that Purex Crystals may irritate sensitive skin and you may want to make a separate batch for babies.

What You Will Need

Fels-Naptha Laundry Soap Bar

Fels Naptha is a natural, powerful stain remover that effectively removes tough stains and dirt from clothing. Fels Naptha is known for its ability to remove tough stains like oil and grease and has been used in households for 100 years.

Castile Soap Bar

Dr. Bronner’s castile soap bar is an organic soap that's good for your body and our planet, made with organic ingredients. Castile soap is gentle enough for babies and pets. There are no synthetic preservatives or chemicals. Castile soap also has natural antibacterial properties.


Borax has antiseptic and antibacterial properties, softens water, and whitens. Borax is great for cloth diapers because it whitens and neutralizes urine odor.

This homemade laundry soap is safe for front loaders and high-efficiency washing machines.

Use three tablespoons per load. For heavily soiled clothes or an extra large load use four tablespoons. For a small load use two tablespoons. It will be tempting to use more soap, but remember a little bit goes a long way. Add the detergent directly to the drum with water before adding laundry. Do not use it in an automatic dispenser; the flakes may clump.
