Soap Nuts Pros and Cons – Should You Make The Switch?

Who would have thought that you could clean your clothes with the fruit from a tree! Well, that is exactly what soap nuts are. Don’t be fooled by the name. These are not nuts, they are actually berries that grow on trees native to India.

I love to save money on laundry and cleaning in general. I have tried a lot of things in the past to reign in the pennies, including making my own laundry liquid. Currently, I use half and half regular laundry liquid along with soda crystals and have done so for a long time.

But is this the best option for my family’s health and for the environment?

So I’m looking at alternatives.

I took a look at Ecoegg. I liked what I found, and I am very tempted to go for that option. While I was doing my research I came across a lot of comments from people who recommended ‘soap nuts’ instead, and I became very curious as to what those were and if they could be better than Ecoegg.

The idea that, like Ecoegg, these nuts could help reduce my plastic usage and be kinder to the environment is very attractive too.

Provided switching out my detergent takes me no more time than I would normally spend on doing the laundry and it saves me money, I am definitely interested. So if you are in the same boat, here are some soap nuts pros and cons to help you decide too.

What is unique about soap nuts is that that when added to water they release a natural soap called saponin. The saponin in soap nuts has natural cleaning powers including anti-fungal and anti-microbial properties which makes them perfect for cleaning your clothes, skin and hair.

Because soap nuts are naturally occurring, they biodegrade easily when spent, and are kind to sensitive skin.

Where to buy soap nuts?

Soap nuts seem to be widely available. You can buy them on eBay or Amazon.

Are soap nuts cheaper than regular detergent?

A 1kg pack of soap nuts can last for approximately 100 washes. Which works out at about 12p per wash or more if you wash at higher temperatures. Of course, the saving will vary depending on how much you pay for your soap nuts. You can reuse your soap nuts a second time on cold-warm temperatures and get even more value out of them.

How long do soap nuts last?

One bag of soap nuts can last indefinitely. It’s important to keep them away from moisture. Soap nuts need water to activate, if you get them wet they will become sticky. As they age they will become darker in colour but will work just the same.

Soap nuts pros and cons

Not sure whether to make the switch to soap nuts? Check out these pros and cons to help you decide.

Soap nuts pros

soap nuts are cheaper than regular detergent

Cheaper than regular detergent

You can save considerable amounts by switching out your regular detergent for soap nuts. Based on 4 loads of week you could get a year’s worth of laundry done for just a £12 outlay. Bear in mind that you might need to spend extra on stain removers if you regularly deal with stained clothing.

Environmentally friendly

Soap nuts do not contain any harsh chemicals that could damage the environment. You can reduce your plastic use by switching to soap nuts too. Think of all the plastic detergent containers you won’t be using.

Kind to skin

Soap nuts are the perfect choice for those allergic to regular detergents or who have skin conditions such as eczema.

Can be used on delicate clothing

Soap nuts are just fine for all fabrics including delicates.

soap nuts can go in the dryer

Can go in the dryer

One of the downsides of the Ecoegg is that you can’t put them in the dryer. If you have a washer-dryer you won’t need to fish your soap nuts out before the drying cycle.

Soap nuts cons

You may need fabric softener

Some reviewers are saying that they needed to use a fabric conditioner, some say not. Personally, I have never used fabric conditioners. But if you prefer extra softness you can stay all-natural by adding vinegar to the conditioner compartment. Your clothes will be softer but won’t smell of vinegar, so don’t worry about that. Vinegar has natural anti-bacterial properties too.

Not so good at cold temperatures

Coldwater washing is possible but you will need to soak the nuts in some warm water first in order to activate the saponin. The great news is that cold water washing should make your nuts last for more washes.

Does not remove stubborn stains

If you are already using a non-bio detergent you are probably already used to pre-treating stains. Spray some stain remover directly on the stain or pre-soak.

Not so great for whites

Soap nuts do not contain whiteners or bleach as some regular detergents do. You might find your white loads becoming grey unless you add a whitener to the load. You can buy natural whiteners to avoid chemical use. Drying your whites in the sunshine will naturally whiten your whites too.

Now my kids are older, I don’t have lots of stubborn stains to deal with. But if I did, I think I might find having to keep pre-treating stains a little tedious, which would be the case with soap nuts. I appreciate being able to just throw in washing and pressing buttons!
