We started using homemade laundry detergent recently and found significant savings in doing so, and our clothes are just as clean as ever. The consistency is way different than store bought, but believe me, it works great!
1 quart water (boiling)
2 cups bar soap, grated (I use Fels-Napha)
2 cups Borax
2 cups washing soda
Add finely grated bar soap to the boiling water and stir until melted.
Pour the soap into a large, clean pail and add the borax and washing soda. Stir well until all dissolved.
Add two gallons of water, stir until well mixed. Cover pail and use 1/4 cup for each load of laundry. Stir the soap each time you use it as it will gel.
You can add 10-15 drops of essential oil (per two gal.) to your laundry detergent.
