Hot Water or Cold Water?
Soapberries will work best with hot or warm water, however, hot water will reduce the number of uses you can get from one soapberry. Washing your clothes purely with cold water is not guaranteed to give the best results, so it is better to first soak the soapberries in hot water beforehand for several minutes and then putting both, the soapberry pouch and the water in the washing machine.
Are Soapberries Strong Enough Detergent to Remove Stains?
Soapberries are perfectly suitable for daily laundry needs, but for tougher stains, you might need to pre-treat and soak your clothes. You can use washing soda as a laundry booster and soak the clothes in the washer for several minutes before completing the cycle. While this might seem like more work, it is a small sacrifice to make for a more chemical-free future.
What About White Laundry?
Soapberries are especially good for washing coloured woollens, silk and other coloured clothing. Because they are completely free of chemical brighteners and bleach, bright white clothing will eventually take on a more natural colour, however colours will keep their brightness for longer. White clothes will not have the same chemically white appearance when washed with soapberries, but you can achieve a comparable result by adding a laundry booster to your load, such as a washing soda, or lemon juice.
