What Are Soap Nuts?

Before we dive into making soap nut laundry detergent, we have to answer the most important question of all: What are soap nuts?

Soap nuts are a berry that come from the soap nut tree. They contain a natural cleaning agent called saponin, which lifts away dirt and suspends the dirt in water so it can rinse away.

If you’re interested in learning more about soap nuts, this helpful guide explains how to use soap nuts and answers a variety of common questions people have about soap nuts.

Benefits of Using Soap Nuts

If you’ve been making homemade laundry detergent but you’re interested in something more natural, soap nuts are the ideal option. Soap nuts have a variety of benefits in addition to being a natural cleaning product.

Since they’re a berry, you can compost them when you’ve used all of their saponin. That makes them perfect for a zero waste laundry routine.

Plus, since soap nuts don’t contain any of the harsh chemicals typically found in store-bought detergents that can leave your clothes feeling stiff, you don’t have to use potentially toxic dryer sheets to make your laundry soft.

Lastly, soap nuts are hypoallergenic, which makes them a fantastic option for anyone who has sensitive or eczema-prone skin.

How to Use Soap Nut Detergent

Your soap nut laundry detergent might settle when it’s sitting on the shelf, so give it a gentle swirl before you use it.

For small loads of laundry, pour 1 tablespoon of soap nut detergent into your liquid detergent dispenser and run your washing machine like normal. For medium loads, use 2 tablespoons.

If you have a large load or a very dirty load, use 3 or 4 tablespoons. People who have extremely hard water have reported that they see better results when they use 4 tablespoons of soap nut detergent.

Storing Your Soap Nut Detergent

Since your soap nut detergent is a natural product, it’s free of all preservatives. This means you’ll want to make the liquid detergent in small batches to keep it from fermenting.

So how do you know if your soap nut detergent has fermented? It’s very easy. Just give it a sniff!

Fresh soap nut detergent should have a slight apple juice smell to it. On the other hand, fermented soap nut detergent will have a distinct sour scent.

To help your soap nut detergent last as long as possible, store it in a clean, air-tight bottle away from direct sunlight. It has a shelf life of 1 to 2 weeks at room temperature. If you store it in the refrigerator, it will last 3 to 5 weeks.

You can also freeze the soap nut liquid in an ice cube tray to make it last even longer. These ice cube trays can hold one tablespoon of liquid in each spot, which makes it easy for dispensing the needed amount when you’re doing laundry.
