Do you know which essential oils are best for cleaning? Or what about for disinfecting?
I used to work as a massage therapist, and in fact taught in an accredited massage therapy course years ago, before I had children. Ever since that time I have always had a selection of essential oils in the house, not just for cleaning, but for home treatment of various ailments. I even still use them in the occasional massage!
Essential oils can enhance your cleaning products by helping them clean, by acting as disinfectants, and of course by creating that lovely “clean” smell many of us are used to. Of course, essential oils are also very concentrated and some are safer than others. There are some oils that should not be used during pregnancy or around young children, or only with great care.
Here’s the low down on seven essential oils to use for good effect. (See notes at the bottom of the list regarding safety.)
Lime, orange & the other citrus oils
The method of soaking citrus peel in vinegar to increase vinegar’s cleaning properties works because of the d-limonene in citrus peel, which is an excellent grease cutter. Citrus essential oils likewise contain this cleaning agent. Grapefruit and orange generally have the highest levels of d-limonene, but all citrus fruit have some (source). They are also effective anti-bacterials, in the this study, for instance lime oil was one of the most effective antimicrobial of the 21 oils studied, though lemon and orange were not far behind.
I typically use lime oil in my disinfectant cleaning wipes and sometimes add it to my DIY spray ‘n’ wipe. I also use it in my “Faux Four thieves” blend that I tend to spray around when there are nasty bugs in the house, as a general anti-microbial. (This is the same as the EO based vinegar disinfectant spray on my non-toxic cleaning printables, only Faux Four Thieves is a much better name, don’t you think?)
Who doesn’t love the smell of Eucalyptus oil? Okay, maybe not everyone does, but I do. I use it in my wool wash and in fact in my ordinary laundry liquid too. It’s the main reason I like to make the liquid, even though the powder is effective for longer. I just love the smell J Eucalyptus oil is also reputed to have disinfectant properties, and to kill dust mites.
Pure eucalyptus oil (ie not the essential oil, though it would probably work too, but at greater cost) makes a good laundry spot stain remover for unknown stains. Pour a few drops onto the stained area and leave for a minute or two. You can also use it to get sticky substances like chewing gum and glue out of clothes, and sticky labels off bottles.
Tea tree oil
Tea tree oil is generally considered to be a good anti-bacterial, anti-viral and anti-fungal. I always keep a bottle around as a general antiseptic, and to as a mosquito repellent. I also use it in my disinfectant cleaning wipes, and it could certainly be used in a four thieves blend. Tea tree oils is also said to be good against mould, but I generally prefer to use clove leaf oil if I have it.
Tea tree oil has been studied relatively extensively, and in particular has been found to be similarly effective against antibiotic resistant strains of bacteria to other strains. Whether bacteria can also become resistant to tea tree oil is unclear, but the balance of the evidence suggests maybe not – though not all the evidence is in agreement here. (source)
Clove leaf oil (also called oil of cloves) is very effective against mould. Clove bud oil, which is more often found in aromatherapy, is less effective against mould, because it has a lower eugenol content (though presumably it has other benefits when used therapeutically). Clove oil was also found to have the second most effective antimicrobial activity in the same study mentioned above, after cinnamon oil, though it’s not clear whether they used leaf or bud oil.
I use clove oil in my faux four thieves spray (with a vinegar base), which I use to clean mould, or a little in the washing machine if I have mouldy smelling (but not stained) clothes. But, I find the smell overpowering, so I tend to use it quite sparingly.
Cinnamon oil gets a mention because it came out as number one in antimicrobial activity, both in the study mentioned above, and in this study, which looked at the efficacy of oils in vapour, rather than liquid form.
Again, it has quite an overpowering smell (though I personally like it better than the smell of clove oil), so I use it sparingly. It does make it into my four thieves blend though. Wild Thyme oil also showed to good effect in that second study, but I really don’t like the smell of it, so I mostly use it only in my faux four thieves spray.
Rosemary also has antimicrobial properties, and as a bonus is often a good remedy for headaches, plus it has that invigorating scent that you probably need if you’re busy cleaning right?
I mostly keep rosemary around for when I have a cold and I add it to my shower disks, but you can also use it in your cleaning products for a lovely refreshing scent. Try cleaning your kitchen floor with a bucket of water to which you’ve added ¼ vinegar and 5-10 drops of rosemary oil.
Peppermint oil had similar microbial efficacy to lemon and orange oil in the first study mentioned above. It also did reasonably well in the second study, though it didn’t have a patch on cinnamon, lemongrass or thyme.
I always keep peppermint oil around for my cold & flu remedies, but it can be also used in cleaning. It’s also said to be a pest repellent, particularly for mice.
Safety & Cautions:
Always keep your essential oils out of the reach of children. Ingesting a couple of teaspoons of some oils could be fatal.
Generally, don’t use any oils on young children’s skin, and especially keep the eucalyptus and peppermint away from their faces, as they can cause some children to have difficulty breathing. Essential oils should also be used with caution by pregnant women: most oils are okay to use in a vapouriser, but not necessarily on your skin, so use gloves when cleaning with essential oils. In particularly, rosemary and peppermint should generally be avoided in pregnancy.
For more information on essential oil safety, the booklet Using Essential Oils Safely by Lea Harris is a good resource. It’s available here (for free).
Which brand of essential oil should you use?
Okay, firstly, let’s dispel a few myths.
1. While price is relevant, an oil that costs a whole lot more, is by no means necessarily a better oil. On the other hand, I personally tend to avoid brands that are significantly cheaper than the ones I find in my health food store.
2. Any oil brand that tells you it’s certified therapeutic is certified by itself. In other words, that is just marketing mumbo jumbo. Oils can be certified organic (look for a certifying body), and in Australia they can be listed with the Therapeutic Goods Association, which means they must be manufactured by someone holding a certification of Good Manufacturing Practice, but not that they have been tested by the TGA. Some essential oils may need to be registered with the TGA which involves more checks than listing, but, most are simply listed. However, registration costs a packet, and smaller companies generally won’t have it. That doesn’t necessarily mean they are shonky (it does mean they can’t legally make therapeutic claims for their oils – they can still sell them though).
3. All essential oils are pure oils, so telling you it’s pure is again, just marketing hype. After all, they’re hardly going to admit it’s not pure are they? That would be the same as saying it wasn’t actually an essential oil.
4. For aromatherapy purposes you want a quality oil, and it makes a difference where the plant was grown. So if the brand of oil you are looking at doesn’t tell you where the oil came from (eg Tasmanian Lavender vs Bulgarian), it mostly likely means it is just an amalgam, which means the outcomes are less predictable. This is certainly a quality signal, but on the other hand, if you are not a qualified aromatherapist, you won’t know whether you want Tasmanian or Bulgarian anyway.
5. Another quality signal is that they list the scientific name of the plant (since there are sometimes more than one plant with the same common name, eg Thyme oil), and where applicable the chemotype, but only some oils have multiple chemotypes (indicted by the letters ct. before a latin word I won’t know the meaning of).
6.If you want to, you should be able to get GC/MS test results from your company of choice, for any given oil. There are a limited number of oil distiller in the world, and most companies get their oil through them. But, if they care about quality, they will be testing them before they package them for you. (I don’t expect you to know how to read the test results, but if you can get them, that’s a good sign).
7. For cleaning purposes, I simply don’t worry too much. Because I’m in Australia I generally buy a TGA listed brand, and leave it at that.
8. If you are in the US, you might find this mini study interesting, in which several brands of tea tree oil were tested by an independent lab (they’ve also tested myrrh and are preparing to test peppermint oil). Most were found to be “compliant” with the norm for tea tree oil, including some brands that are relatively inexpensive.
Now over to you: Did you guess what my seven oils would be? Do you use essential oils at home? Do you have a favourite oil, or a favourite way to use them?
But wait, I have more questions: if you don’t already use essential oils, why not, and will you try some now? If you do use essential oils do you go by what smells good to you, or by the actual cleaning and disinfectant qualities? (Tip: There is no “right” answer to this question – I go by both!)
