Liquid soap nuts
Soap nuts, soapnuts, soapberries, etc are names for Sapindus the species of shrub of which the drupe (fruit pulp) is used to make soap. Soap nuts require hot water to activate and may not work effectively in cold water at all. Turning the soap nuts into a liquid detergent will allow the use of cold water.
- Crush the berries before boiling to release as much of the saponins as possible. Crushing the berries in a muslin bag will make it easier to crush and won't leave a mess.
- Boil two berries for every one cup of water for 30 minutes, leaving the berries in the muslin bag (or just let them roam free). Regularly top up the water as it evaporates.
- Allow the water to cool then strain the solution. Store in a jar in the refrigerator.
Usage: 1-3 ounces per load, depending on HE or not.
Use the leftover soap nuts in the muslin bag in the washer for one load of laundry.
