The zoo knows something you might not.
On our last family trip to the zoo, my attention was caught by the standard announcement at the stingray touch experience. They tell everyone to roll up sleeves (even short sleeves) and pull back long hair. Want to know why? Because there is detergent and shampoo residue in your clothes and hair that would make the stingrays sick. Most people probably heard that and thought nothing of it. Me? I was struck by the fact that the zoo worries about all that stuff making the stingrays sick and we walk around with it every day.
I’ve been on the lookout for a safe, natural, frugal laundry soap for a long time. I make so much from scratch, and I really didn’t want to crank out homemade laundry soap. I didn’t want to shell out lots of money for expensive natural laundry detergents either. I think I’ve finally found my winner!
What are Soap Nuts?
Soap nuts are actual fruits that grow on trees, rather like olives, then are dried. They are completely chemical-free, non-toxic, hypoallergenic, eco-friendly, unscented and gentle on clothing and skin. They contain a compound called saponin, which acts as a natural surfactant to clean your clothes (or anything else). A surfactant is simply a cleaner, something that lifts dirt off the surface of something else. Soap nuts can also be made into cleaners for other parts of the house, even the kitchen, but I’m so impressed with what they do in the washing machine (and was so direly in need of a natural laundry detergent) that I haven’t even tried them elsewhere yet.
To use soap nuts in the laundry, you simply put 5 of them in a little bag and toss them in the washing machine. They can be reused 3-7 times before their saponin runs out. For a cold water wash, they work best if you put them in a cup of hot water for a few minutes first to begin releasing the saponin. I thought this would be a pain, but it’s really not a problem. I just put them in an old detergent bottle cap while I loaded the machine or sorted the load, and then they were ready to go in. You also don’t need fabric softener or dryer sheets with soap nuts.
How I Put Laundry Soap Nuts to the Test
How can you tell when a laundry soap is doing its job? I think this is a tough product to review, because it seems like no matter how great your laundry detergent is, there’s always a stain or a grease spot that sneaks through here and there.
When I tested soap nuts, I tried to really pay attention to the job they were doing. I washed towels and sheets first, and I was pleased that they smelled so clean afterward. What does clean smell like? Nothing. My sheets smelled pleasantly like nothing. I would call it a fresh scent, but years of marketing has probably brainwashed you into thinking that “fresh” means “lemon” or “powder” scented (blech). In reality, a “fresh” smell is a lack of any negative odor, don’t you think? That’s what my first two loads smelled like.
I washed a warm load next and didn’t have any problems with it, but this is where laundry testing gets tough: how do I know the soap is working? Especially since soap nuts don’t have the sudsing action that we’ve all come to expect with commercial detergents, I didn’t have anything to trick me into thinking they were cleaning my clothing.
I decided to stretch the soap nuts a little and offer the challenge of a cold load. I took note of the food crusted on daughter’s bib, and I decided I had the clincher: my exercise clothes, fresh with sweat and rank with odor, in a cold load of laundry. I figured if the soap nuts could make them smell sweet, they definitely are doing something powerful in there! I tentatively lifted the wet exercise clothes to my nose, a little nervous that I was inviting noxious fumes up close and personal on purpose. I was amazed – they smelled fresh and clean. Soap nuts, score one, sweat, zero! Soap nuts work. They clean your laundry. Effectively. Even in cold water.
Score two for soapnuts: they also took smell out of a stinky towel that had been used to clean up a kefir spill. It smelled like puke. Now it doesn’t. Woo hoo, soap nuts!
My favorite part of using soap nuts? I can wash the whole family’s laundry together instead of separating out baby clothing to wash with the more expensive “natural” or “sensitive” laundry detergent. Soap nuts are ideal for sensitive skin (my kids have that) and leave no residue, so I don’t worry about them being exposed to X-something-or-other-chemical left in their clothing or on their sheets. And the stingrays are safe, too. 🙂
One major drawback is the tendency to push the soap nuts farther than they can go. Because there’s a range of loads (3-7) that you can use one batch of nuts for, I tend to try to use them as long as possible. Frugal, conservative momma. Sometimes I end up having to rewash a load, like the load of camping laundry that still smelled like smoke after being washed. I don’t like the waste of water there. To soap nuts’ credit, I may have pushed the size of that load a bit much for how stinky the clothing was, too, along with my nuts being on their last legs. (Soap nuts instructions say to use medium loads so that there is enough room to agitate the clothes with the saponin.)
Here are some tips (with pictures) on how to tell if laundry soap nuts still have any cleaning power left.
Another Choice: Soap Nuts Extreme 18X Green Cleaner
I also got to try NaturOli’s somewhat processed product, a liquid made from soapnuts. It’s basically soap nuts “tea” with some preservatives so it doesn’t go bad in a week (you can make your own from the soap nuts themselves, but it doesn’t keep). It’s a funny feeling putting just a teaspoon of liquid into my cavernous washing machine with a whole load of clothes and expecting anything good to happen. I’ve found that the Soap Nuts Liquid Laundry Detergent Concentrate works just the same and just as well as the actual soap nuts. If you might have a tendency to “push” the nuts like I did, you may want to try the liquid. Think of the plastic you save buying something that concentrated! My sample bottle was supposed to last for 6 loads, but I’m pretty sure it’s gone farther than that – the kind of added bonus I just love!
But How Much Do Soap Nuts Cost?
It drives me nuts that the natural cleaning products always seem to cost double the regular ones. I am tickled pink with joy that this one doesn’t! As long as you buy in bulk, you could get the 32 oz. – 320 loads for $28.95, or the NaturOli Soap Nuts 48 oz gets you 480 loads for around $45.95. (I’m thinking about splitting a bag with my mom.) Either one works out to under 10 cents per load (plus the possibility of more if you make your nuts stretch by using cold water!). I figure my price point for All Free and Clear is $3.00 for 32 loads after a coupon and sale match-up, or 9.3 cents per load. Soap nuts are almost exactly the same price per load, and I don’t have to watch for a sale or cut the coupon. Love it!
Wondering about shelf life? Here is the answer from NaturOli:
Soap nuts basically have an endless shelf life if properly stored. If the user plans to have them around for several months, we recommend that they remove them from the muslin bag and store them in an air tight container. They should be stored in a cool, dry, dark location away from direct sunlight. Most laundry rooms are the perfect location!
Someday I’m going to try NaturOli’s Soap Nut Natural Shampoo Bar. I’m kind of in the market for a new chemical-free, natural shampoo. You don’t even want to know what I’ve been using for shampoo this summer!
You Can Also Use Soap Nuts for:
- cleaning carpets
- stove tops
- washing dishes
- all-purpose cleaner
- and more!
For most of these uses, you need either the 18x liquid OR you can make your own liquid using the nuts (directions come with the package). However, if you make your own liquid, because there isn’t a preservative it will only last a week and you have to keep it in the fridge (therefore, it’s not my deal because my fridge is always too full!).
Practical Tips for Soap Nuts in the Laundry Room:
- First, know that the shelf life of these buggers is very, very long. Just try to keep them out of moist air and in a cool place (like maybe…your laundry room).
- How to figure out if the soap nuts can handle another load: I mentioned that I was always tempted to overuse the soap nuts, since they can last for 3-7 loads. The gals over at NaturOli helped me out with this uber-tip:
“We recommend that if people aren’t sure about how much “juice” is left in the soap nuts after several loads that they take the bag with the soap nuts and let the water filling the washer run over it then squeeze the bag. If you see suds and or feel that slightly slipperiness of the saponins there’s enough for another load. Gauge amount of slippery feeling to how large a load. You can also add one or two new soap nuts to the bag of the used ones if you’ve already loaded a big load and you don’t get much of a feeling of slippery when you squeeze the wash bag.”
This is so easy to do! It’s much less subjective that trying to figure out when your soap nuts look “tan” or “soft” per the instructions that come with them. I tried the “sudsing” method with a bag of soap nuts that I was about to compost, and they still had suds. So just from this tip I got an extra freebie load of laundry out of my soap nuts. Love that!
- Soap nuts last longer if you wash in cold water. Just remember to “activate” them by soaking in hot water in a little cup while you sort clothes or something.
- If you can figure out when your rinse cycle starts and can make it to the washer in time (this is not a tip I will ever take advantage of!), you can pull the soap nuts bag out to make them last even longer!
- If you get the Soap Nuts Liquid Laundry Detergent Concentrate, it only takes a teaspoon for a whole load. Don’t try to guess. You’ll want to put an actual teaspoon with your bottle to make sure you’re not wasting the liquid by overdoing it.
- I just used the last of my liquid today (sniff!). That is sad, but the happy news is that there were DEFinitely more than 6 loads in there. In retrospect, I should have counted for you all, but I did not. I used a “scant” teaspoon in each load – of course – frugal Katie. Worked great for me!
- I like to make sure my soap nuts dry between loads by hanging the whole bag to dry. My washer has a little tab on the inside of the door that is perfectly convenient.
- Like with most laundry soaps or detergents, many stains (at least in families with children!) still need a pre-treatment or even a soak. Soap nuts do not claim to be superstars in the laundry room, just an environmentally friendly option. I have some tricks up my sleeve for pre-treating laundry stains.
- Something cool: soap nuts make towels fluffier!
