Liquid Laundry Soap

I was surprised that I did not have a recipe for liquid laundry soap on my blog. I have recipes for soap mousse, fabric softener, bleach alternative and several other recopies but nothing for liquid laundry soap. I intend to remedy that right now.
Some of my family like to use the liquid laundry soap and some like the soap mousse and some don't care one way or another. I had at one point been able to purchase several jugs of liquid laundry soap for a small price so I have not made my own for quite a while. The stock of store bought soap is down to almost nothing so now is a good time to make a batch of my liquid laundry soap to replace it. I have saved a few of the bottles from the store so I can fill them when the soap is ready.
Here is the recipe I use for liquid laundry soap.

1 quart Water (boiling)
2 cups Bar soap (grated)
2 cups Borax
2 cups Washing Soda

■Add finely grated bar soap to the boiling water and stir until soap is melted. You can keep on low heat until soap is melted.
■Pour the soap water into a large, clean pail and add the Borax and Washing Soda. Stir well until all is dissolved.
■Add 2 gallons of water, stir until well mixed.
Once the mix is cool I add several drops of essential oils. Lavender, tea tree or other fresh smelling type.
■Cover pail and use 1/4 cup for each load of laundry. Stir the soap each time you use it (will gel).
Since I put mine in used laundry soap bottles I shake before use not stir.
