How to make dish soap
How to make dish soap (and veggie wash and hand soap): Add a handful of soap nuts (a.k.a. soapberries) and two cups of tap water to a glass jar with a tight lid. Shake until you get bubbles. Pour about half a cup of the solution into a sink full of dishes. Refill the jar (or reusable dispenser) with water. Use this solution until the soap nuts smell bad, then compost and start a new batch! https://goo.gl/syFP6g (Video credit: Shannon Ruth Dionne Photography)Posted by David Suzuki's Queen of Green on Friday, October 7, 2016
DIY dish soap recipe that really works was impossible to find...until now!
Queen of Green liquid dish soap recipe
One handful soap nuts (a.k.a. soapberries)
Half a litre (2 cups) tap water
Add ingredients to a glass jar with a tight lid. Shake the jar before each use. When you get bubbles, pour about 125 ml (½ cup) of the solution into your sink. Refill the jar with water. Use this solution until the soap nuts stop making suds or smell bad. Then throw them in the compost and start a new batch.
Personalize this recipe by altering ingredient ratios for desired results — success will depend on the hardness of your water and dish grime. You can even add the solution to a pump soap dispenser.
Note: wash fruits and vegetables with this recipe, too!

How do soap nuts work?
Soap nut shells contain large amounts of natural surfactants called saponins. Surfactants lower a liquid's surface tension and so can be used as detergents or foaming agents. You can find soap nuts in many health food stores and organic grocers or online.
I know soap nuts aren't local. But they have other eco-friendly qualities: They're biodegradable, certified organic, free of scents, plastic and toxics, and many companies ensure local producers (e.g., in India) are paid fair wages.
Have you found a great use for soap nuts?
