31938111 uses for castile soap

I’m all about streamlining, consolidating, multi-purposing and simplifying, so when I find a product that fits that bill I get really happy. Enter castile soap. Behold people, here is a product you can use to wash your face AND your toilet AND keep bugs off your plants. Noice!

just a really cool bathroom that doesn't have much to do with this post. Check out more cool design ideas on my pinterest page. image via digsdigs.

It means I don’t have to buy 281 different products for personal care and household duties. Double noice!

I mention it a fair bit in my Natural Beauty Guide, which you can grab a copy of for nothing HERE.

what’s castile soap?

Saponified olive oil usually mixed with other plant oils like coconut, palm or hemp oils. It comes in a liquid or solid form. It’s super mild because it doesn’t have any of the harsh surfactants or other animal or petroleum-derived additives that feature in other types of soap. It’s mild enough for use by people with sensitive skin, and also good for babies and kiddies. You only need to use a tiny amount, which is a bonus. And because it’s a truly natural soap, not a chemical detergent, it’s completely biodegradable and won’t harm the environment.

Use it in place of shampoo
Use liquid castile soap straight up to wash your hair, or mix it with essential oils for a bit of aromatherapy action and/or to help scalp conditions. Use a ratio of 100ml castile soap to 20 drops essential oil. Alternatively make a herbal shampoo by mixing 70ml castile soap with 30ml herbal infusion in a reusable bottle or glass jar. My Natural Beauty Guide has some ideas for which herbs and essential oils are good.

P.S If you’re switching from shampoo, I recommend de-gunking your hair with bicarb soda first, for at least two weeks. Shampoo contains ingredients like silicone that build up on your hair over time. You want to get rid of all that so your hair can benefit fully from using all natural ingredients. Castile soap can also build up a little on your hair – if this happens just use a weekly or fortnightly bicarb wash.

Wash your face and body with it
Yep, castile soap is so mild you can wash your face with it. You only need a tiny squirt.

Use it as a dishwashing liquid
Use it straight out of the bottle or mix it with some distilled white vinegar. A safe dishwashing liquid for you and the environment!

Wash your clothes with it
Use it to wash your delicates by hand or try this recipe for home made washing detergent. 

Wash your dog with it
Safe and mild enough for puppy skin too.

Use it as a multipurpose cleaning spray
Almost fill a 1L spray bottle with water, then add 1-2 tablespoons castile soap and a few drops of essential oil if you like. Shake well. Use it as a bench spray, window or shower cleaner.

Clean your toilet with it
Pour a little liquid soap into the toilet bowl and scrub with a brush. I like to add a few drops of eucalyptus oil as this kills bacteria and deodorises.

Make an organic pest spray for your plants
Use this spray to ward off aphids, caterpillars, mites, scale or whitefly. Almost fill a spray bottle with water then add 1 teaspoon liquid castile soap. Shake well and spray on plants.

Make your own white oil spray with it
Use this one for stubborn mites, scale or whitefly. Pour 500ml vegetable oil and 100ml liquid castile soap into a large jar or bottle with a secure lid. Shake well until blended. Store it in a cool spot. To use, shake well and add 1 tablespoon of concentrate to 1 litre of water. 

Clean your floors with it
Fill a bucket with warm water. Add 2-3 tablespoons of castile soap and mix. You can add a few drops of essential oil for aroma if you like.

Use it in place of toothpaste
I just tried this one. Squirt a tiny amount onto your toothbrush and brush as usual. Make sure you rinse really well. The taste is okay, but I might add some peppermint oil next time.

where can I buy castile soap?

From most health food shops. Look for brands that list olive oil at or near the start of the ingredients list, which indicates it’s made mainly with olive oil (which makes for a gentler soap). Go for one that is locally made. There’s often soap makers at farmers’ markets also. I buy mine – Robyn’s Soap House - from my local market.

You might have to try a few different brands until you find the one you like. I’ve had mixed results with the various brands. The one made in the US I find too drying for my skin and hair. There’s one made in NZ that is okay, but Robyn’s is the best one I’ve found, by far.

Cool tip: the soap maker I buy from told me you can thicken castile soap, which is normally quite runny, by adding a tiny bit of salt and shaking the bottle every day until it’s dissolved. I tried it. It works!

Are you a castile soap fan? Got any swanky uses for it not listed here?


  1. I love liquid castile and use it for washing dishes. I mix 500mls of liquid castile with 500mls of warm water and add some essentiall oils (sometimes lavendar, sometimes lemon). A small amount goes a long way.

    I wash my hair with bi-carb and rinse with ACV. Could I mix a few drops of castile in with the bicarb paste??

    1. Haven't tried doing that... not sure how it'd go. Let us know if you try it!

  2. I use castile soap as a body wash and shampoo. it leaves the skin lovely and soft. I love it. Very expensive though.

    1. That's true, it is dearer than regular soap but the quality is much better and seeing as you don't have to buy other cleaning products, it makes up for it.

  3. We make our own castille soap and we use it for all of the above except toothpaste. Great stuff! Works really well as a shampoo.

    1. Hi Kim, how do you make it? Do you purchase lye or use something else? Would love to know your recipe!

  4. I love Robyn's Soap House too!

  5. Tea tree soap is a fantastic soap I use it. After using this soap remove my spot and darkness.To get more information http://www.vegantreeowl.com.au
