Soapnut Recipes & Uses


Place 3-6 whole cracked shells (or equivalent in pieces) into a washnet, close with an elastic band around the top and place into the tub with your laundry. You can use the soapnut liquid if you prefer; see below.

Remove the nuts after the cycle has finished and let dry (if there's time) before your next load.

The number of nuts you use depends on the size of your load and how dirty the items are, as well as the hardness of your water and the efficiency of your machine.

For example, use four nuts for a large, dirty load, in an old washing machine using hard town water, and two to three nuts for a small or normal load in a modern machine using rainwater.

The temperature of the water is also a factor, as hot water will make the nuts release their surfactants quicker so you'll have to replace the nuts more frequently but the cleaning power will be stronger.

Washing your laundry in cold water is perfectly fine depending on how dirty your laundry load is. We recommend experimenting to find the best quantity required for your personal needs.

One lot of soapnuts can be reused until they lose their sticky, soapy feel and look pale and squishy on the inside, and are brittle when dry (4-6 times). When they are spent, throw them in the garden or compost.

You can also use them for handwashing by putting them into your laundry tub and running water over them, then adding your clothes for a soak and hand wash. This method is perfect for very delicate garments and materials, as well as fleeces.

Soapnuts can be safely used for children's clothing, nappies and bedding, as well as for washing their stuffed animal toys. The soapnuts will not leave a residue and will kill bacteria, microbes and dust mites.

The same can be said for pet bedding and blankets, leaving it residue-free, clean and smelling fresh.

Whole Soapnuts

Whole soapnuts can be used for much more than just laundry!

Here are some uses for whole soapnuts:

  • Dishwashing (place them into your sink or into a stocking in your sink and run water over them)
  • Dishwashers (place soapnuts in a bag into the bottom of the cutlery holder)
  • Washing the car (put soapnuts into a bucket, half fill with hot water and let steep for ten minutes or more, then wash the car)
  • Let us know what other uses you find!

Liquid Concentrate

Place 100 grams of soapnuts with 3 litres of water in a large saucepan or stockpot (this will make 2 litres of liquid - you can make smaller amounts by using 2 cups of water and 4-6 nuts).

Bring to the boil, reduce heat and simmer for an hour or so. 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 glycerine. 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.

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 the stain and blot clean)
  • dishwasher soap (liquid in dispenser section with optional 1tbs vinegar as a rinse aid)
  • pest spray (use a spray bottle to spray bugs on plants)
  • glass cleaner (1tbs soapnut liquid, 1 tbs vinegar and 1 cup water)

Here are some more amazing ideas from Dorothy, a soapnut specialist in North 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 fibreglass 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 your 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 of washes to get all the chemical residue out initially, from your old shampoo.

Preserving Soap Nut Liquid

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.

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!).

Adding Essential Oils

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

We will have safe suggestions here soon. In the meantime, have a look online as there are plenty of wonderful Australian essential oil websites.

Our favourite oils are Eucalyptus, Lavender and Orange. They leave laundry smelling wonderful. Try Rose, Sandalwood, Vanilla or Musk as a real treat!
