Do Soap Nuts Really Work?

I have tried several well-known and popular cloth diaper-safe detergents and was perfectly happy with them, but I was always curious about soap nuts.

I was intrigued and confused by how they worked. How could something that looks like a plastic walnut clean dirty diapers of all things! I had to know so when they were on one of my daily deal websites, I ordered them and haven’t looked back!

Note: Eco Nuts is no longer in business, but there are other brands of soap nuts, also called soap berries, available. They all work in the same way.

What Are Soap Nuts?

Soap Nuts are a berry that grows in the Himalayas that naturally produces soap. That soap is called saponin, a natural cleaner that works as a surfactant, breaking the surface tension of the water to penetrate the fibers of your clothing to lift stains from the fabric, and leaving the dirt suspended in the water to be rinsed away.

For diapers, you put three nuts into one of the bags that are included in the box and four to five soap nuts for regular laundry. Drop the bag in with your laundry and that’s it! You end up with clean, odorless diapers and laundry!

They really do work and it’s a wonderful alternative to regular detergents for delicate laundry or a more green option. I have even started using them on our regular laundry and they’re fantastic!

You can reuse the nuts until they dissolve or remain soft, I find that I get about 5-6 uses out of one bag! I ordered these two boxes at the end of December and I still have one and a half boxes left! So not only do they work wonderfully, but they’re also economical.

The next time you’re looking to make washing your laundry more eco-friendly, give soap berries a try. I love them and I’m pretty sure that you will too!

  14. I have never even heard of a soap nut before. How crazy is that?! Very cool. I’d definitely give it a try. But, I am curious…is it a sustainable solution?

    1. I would imagine that yes, it is sustainable. You don’t have to chop the trees, just pick the nuts. Plus the nuts are compostable. They really are great even if I still don’t really “get” them. All I know is that they work! 🙂
