(Soap) Nuts about laundry

As you know, I really don't like using chemicals in the house or for the animals, but it is gradual process to reduce and change what we use.  For the laundry, we already use a grey-water friendly product, as all the washing-machine water is used to water my vege garden, however I was sure there was still opportunities to improve.  I'd read a bit about soap nuts and thought about it and hadn't done anything about it until I saw them at the local market and finally bought some.  I admit that I was a little skeptical, and I do have a boilermaker husband who can come home in some pretty dirty work clothes, so these soap nuts had a challenge ahead of them.

soap nuts are actually dried berries
For those who haven't heard of soap nuts, they're actually a dried berry from the sapindus mukorossi tree, which grows in India and Himalayas.  They are imported to Australia by various companies (just google soap nuts and you will find them).  This is the only thing that worries me about soap nuts, I would prefer to use something local, but then you can't really fault supporting industry in those countries either.  As far as I can tell, we can't actually grow the tree in Australia, the guy I bought them from said it is a weed and the fine is $20,000, and as the nuts are irradiated at customs its pretty much impossible to get the seeds to grow anyway, more info here.  If I could get an Australian equivalent and grow it in my garden, that would be the ultimate self-sufficient laundry solution!  Any ideas?  

**Last minute update: I am excited, I just read about the soapwart plant (here and here), and I should be able to grow that in my garden and use it for various soap applications, but until I get that established, I have soap nuts**

Anyway, moving on with the story, the idea with the soap nuts is to use the coldest wash available, pop 4-6 nuts in the little calico wash bag, put that bag in with your washing and they should last a few washes, not as many if you use hot water.  We normally use either a 45 min quick wash, or the 2 hr "cotton" wash for the boilermaking clothes, so I've tried the nuts a few times on both of those wash cycles.

I took some before and after photos of some of our really dirty jeans, because I thought they would be the hardest to get clean.  In general I've been pretty happy with results.  As you can see these jeans got as clean as I would have expected from the bought laundry powder we usually use.  They don't always come out perfect, but they are only going to get dirty again, so we don't worry so much about work clothes anyway!  Pete has requested that his work jeans are washed in hot water with laundry powder so that he looks presentable before he gets dirty again.  But apart from that, I think soap nuts are great for all other laundry.

The main thing I noticed was that the washing didn't smell of anything.  Normally it has that added fragrance, so you know its "clean", that was really weird at first, but good because I don't like artificial fragrance!  After the first wash I added a few drops of lavender oil to the powder dispenser, and then the washing smelt like lavender, which was much nicer.

The main difficulty I have with the soap nuts is remembering to find the nut sack (te he) from one load and putting it into the next load if I'm doing a few loads in a day.  I have wars with that washing machine, and you will notice that the handle is missing, yep I broke that off one time ages ago when it wouldn't let me back in, so the problem is that once you press buttons the door locks and its too late to add the nuts.  But I just have to get into the habit, and its not too late to add powder if all else fails!

I also used the nuts to do some hand washing, just soaked the nuts in hot water for 10 minutes, added some lavender oil and washed as normal, no problems and less suds to rinse out as well.  This website has lots of great tips for other uses for soap nuts.

The nuts are also supposed to work out way cheaper, however I'm not so sure.  One website has them for $26 for 500g, which does over 200 washes, I get 60 washes from my current washing powder  (reading the box, not counting personally), for about $10, so its a bit cheaper, but I also like to know that the water going to my garden is as chemical-free as possible.  If you buy in bulk it works out even cheaper.  You can get Soap Nuts at Biome (affiliate link).

Have you tried soap nuts?  Do you like them?

  1. I like the soap nuts too, but much prefer the soapwort, it's free and pretty in the garden:)

  2. thanks Molly! I got the soapwort idea from your blog (see the link), and I've bought a little one from the market. I'm really happy to find something that I can grow myself :) Have you posted a recipe for using soapwort?

  3. I have soapnuts- I love them - I have tried putting them in the was bag and also boiling them and putting the liquid in a clean bottle.
    I prefer the liquid and make it up once a week. I add some drops of Broad leaf eucalyptus oil as a scent and preservative (leaves a very faint scent). My husband hates anything 'natural' and is not at all interested in anything else. He will only use shop bought detergent however. He refuses to believe it could work as well unfortunately.

  4. Soap nuts are awesome, your examples prove how well they work too! I've been using them for a while myself, I should share some before and afters of my own washing but I never remember to do it when its wash time :(

  5. I used to wash farm pants with ground in grain dust from stacking bags of grain, it would budget from one wash to the next in a twin tub. Then one day I had to stop the machine for 2 hours, I restarted and continued the washing and the pants were clean, itvwould seem a short wash, long soak then wash will shift the problem stuff.
    I have seen documentaries on traditional indigenous women using soapy plants to wash maybe that was what you were able to buy.
    Good luck with the results.

  6. Darn spellcheck....'wouldn't budge '

  7. Thanks for this information. It is always helpful to know what is on the market.

    There is an Australian soap tree and on our recent trip up north this was demonstrated to us by a bush man at Tennant Creek. Just add water and scrub and this plant lathers up. Not sure if it can be used for washing clothes though. Here is some information about the soap tree.

How to make coconut yoghurt

Lately I have been cutting back on eating dairy.  I know, I know, we own two house cows!  But I am trying to heal inflammation (bad skin) and dairy is one of the possible triggers, so as a last resort and after much resistance, I decided I had better try to cut back.  Its been hard because I eat a LOT of cheese, and cook with butter, and love to eat yoghurt (and have written extensively about making yoghurt).  I had to just give up cheese completely, switch to macadamia oil and the only yoghurt alternative was coconut yoghurt.  I tried it and I like it, but only a spoonful on some fruit here and there because it is expensive!

The brand I can get here is $3 for 200 mL containers.  I was making yoghurt from powdered milk for about 50c/L.  So I was thinking there must be a way to make coconut yoghurt, but I didn't feel like mucking around and wasting heaps of coconut milk trying to get it right....  and then Biome Eco Store sent me a Mad Millie Coconut Yoghurt Kit to try.  The kit is…

What to do with eight acres

Behind the scenes of my blog I can see the search terms that led people to find my blog.  It can be quite interesting to look through them occasionally and see what people are looking for.  Most of them involve chicken tractors, but another question that comes up regularly is “what can you do with eight acres?” or “how much land is eight acres?”.  Today I will try to answer this question.

Of course it is a very broad question, there are lots and lots of things you can do with eight acres, but I’m going to assume that you want to live there, feed your family and maybe make a little extra money.  I make that assumption because that’s what I know about, if you want to do something else with your eight acres, you will need to look somewhere else.

If you haven’t chosen your land yet, here a few things to look for.  Focus on the things you can’t change and try to choose the best property you can find in your price range.  Look for clean water in dams, bores or wells, either on the property …

We don't have any cling wrap either

Last week I wrote about how we don't have a microwave and I really don't miss it.  So continuing the theme of "weird things about my kitchen", we also don't have any plastic cling wrap or paper towels.  And we haven't had them for so long I can hardly remember why we ever needed them.

I always thought that cling wrap was wasteful.  Not just from an environmental perspective, but I also didn't like spending money on something that I only used once.  When I was at uni and took sandwiches for lunch, I used to bring home the cling wrap and use it again until it didn't stick anymore.  One year when we did Plastic Free July (I can't remember when exactly - here's what I wrote last year) we decided to stop using cling wrap.  I used up the last of it recently when we were painting (its really hard to renovate without creating waste) - its handy for wrapping up paintbrushes and sealing paint temporarily, however I do not use it in the kitchen.
