Tip: Soapberries are relatively working in cold water, however, for dirtier load we recommend higher temperature mode to release the saponin better.
Otherwise for cold water use, we suggest you presoak the small wash bag with berries in the hot water until enough saponin is released and then load the water filled saponin and bag in the machine
For white wash, you could use vinegar or baking soda for extra power booster for cleaning or other bleach for heavy stains or extra whitening.
