Place the equivalent of five whole soapberry shells in the small cotton bag provided.
Add bag to normal washload and remove when finished. Use warmer water for heavily soiled loads (40-60 degrees).
Re-use the same shells for approx. three more loads.
If you prefer a scent on your laundry, pop a few drops of your favourite essential oil on the wash bag (such as lavender or eucalyptus).
When finished, shells are thin and brittle, at which point they can be added to your compost to break down naturally.
You can also make a multi-purpose liquid by boiling the berries for 15 minutes and using the liquid for anything, from shampoo to a cleaner.
