Soapnut Liquid Recipe

Basic Directions

  1. Place 100g of soapnuts with 3 litres of water in a large saucepan or stock pot (this will make 2 litres of liquid - you can make smaller amounts by using 2 cups of water and 4-6 nuts).
  2. Bring to the boil, reduce heat and simmer for an hour or so.
  3. Strain the liquid through cloth and compost the nuts.

The concentrate will have a watery consistency and small dense suds. It does not contain foaming agents and thickeners like chemical detergents do, but it still has the cleaning power!

To thicken the concentrate

Add a little cornflour (try 1 teaspoon in 1 tablespoon boiling water, then add to liquid concentrate) or glycerin. This will create a more suitable consistency for use in a pump pack.

Leave the liquid thin for use in our foaming bottles (no additives required). For best foamy results, let the concentrate sit overnight and just use the clear liquid in the foamer bottles. The sediment at the bottom can be used for all other bottles, but the foamers have a very fine mesh filter which will become clogged.

Uses for soapnut liquid

The concentrate can be used as is or diluted for all your cleaning requirements, such as:

  • laundry liquid (1-2 tbs in the detergent drawer)
  • hand soap (use in a foamy pump pack)
  • shampoo (replaces shampoo and conditioner together, try a spray bottle!)
  • pet shampoo (leaves hair soft and silky, will also repel fleas, mites, ticks, mosquitoes etc)
  • general purpose cleaner for the kitchen and bathroom (use with a cloth from the jar or spray bottle)
  • carpet cleaner (spray or sponge onto stain and blot clean)
  • dishwasher soap (liquid in dispenser section with optional 1 tbs vinegar as a rinse aid)
  • pest spray (use spray bottle to spray bugs on plants)
  • glass cleaner (1 tbs soapnut liquid, 1 tbs vinegar and 1 cup water)

More Ideas

And here are some more amazing ideas from Dorothy, our soapnut specialist in Nth QLD:

  • "I used the full concentrate on rust on our Golf Buggy trailer, and it cleaned it off beautifully
  • It also cleans up a car engine magnificently
  • Cleans fiberglass and even makes a bit brighter
  • I repel ants from the house by spraying soapnut concentrate with a drop of tea tree oil in it and spray all around the outside of the house. The ants will not cross the line. I also sprayed Green ants nests and they have not returned
  • Fruit trees sprayed in a weaker solution, no bugs or moths etc.
  • After I have used the nuts for the laundry, before composting I boil them up to get the last of the saponin out and use this weak solution for trees etc. then I compost them."

Use the cleanser as you would any other cleanser, in a jar or spray bottle or pump. There may be some sediment, so shake before use.

Refill your shampoo and detergent bottles to save on packaging and the environment. A note about the shampoo - there will not be suds. Oils make the bubbles disappear, but rest assured, the soapnut liquid is removing the excess oils from you hair (which is the aim of the game). Use enough so that your hair feels all silky when you rinse it. It may take a couple washes to get all the chemical residue out initially, from your old shampoo.


Soapnut liquid concentrate (or soapnut 'juice', if you like) has approximately a 2 week shelf life on the kitchen bench, or at least a month in the refrigerator.

The addition of an antibacterial oil, such as eucalyptus oil, will extend the shelf life further still.

We have also had great success with citric acid (available easily from supermarkets, or at our Online Store), just use 1 teaspoon per litre. Dissolve the citric acid crystals into 2 tablespoons of hot water, then stir into the strained soapnut liquid.

We have recently trialled potassium sorbate, and have found this to be even better than the citric acid. Less is required to be used, and in our tests the soapnut liquid has lasted longer before starting to ferment.

The liquid can also be frozen for long term storage. We like to make it as we need it, each month, and store it in a jug in the refrigerator. We fill our spray bottles and foamy bottles as we need to, and the last bit left over each month is used in our washing machine.

Because this is a totally natural product, the 'juice' will eventually ferment, turning into 'soapnut wine' (though we do not recommend drinking it!).

Essential Oils

Essential oils can be added to give your homemade cleaner a pleasant scent, additional antibacterial qualities and for therapeutic benefits.

Soapnut liquid concentrate is the perfect carrier for any essential or fragrant oil you desire. The oils may rise to the top of the liquid, so shake before use.

Please note that oils can have strong effects on the body and well being and adequate research is required into which oils are right for you. Some oils are irritating to the skin and unsuitable for sensitive skin and skin conditions.

Our favourite oils are Eucalyptus, Lavender and Orange. They leave laundry smelling wonderful. Try Rosemary, Rose Geranium, or Peppermint as a real treat!
