One of the really fun things I get to do is mess around with DIY cleaners.  The inner chemist in me comes out and I play around with different formulas until I get something just right.  My bloopers not withstanding, I can usually muddle my way through a recipe and make it work with minor adjustments here and there.

Today I would like to show you how to make your own liquid castile soap for pennies.  Well not really pennies but two full quarts of liquid castile soap for less than $1.50.  Compare that to Dr. Bronner’s at $14 or $15 dollars per quart and you will see why I am excited.

What is Castile Soap?

Castile soap is wonderful stuff.  It is made from 100% plant oils – typically olive oil or coconut oil – and it includes no animal fat and no mysterious chemicals. It’s a true soap, not a chemical detergent, making castile soap completely biodegradable and very earth-friendly. This means it is also skin friendly unlike traditional soaps which can be extremely drying.

fThe big kahuna in castile soaps is Dr. Bronner’s which makes a great product that simply grows on you.  It comes in many wonderful fragrances (I like the Rose and the Peppermint) and the liquid version is concentrated so that a little goes a long way.  The downside is that at $14 or $15 for 32 ounces, it is expensive.  Dr. Bronner’s also makes a bar soap that sells for about $4 to $5 per bar.  I will tell you why all of this is important in a moment.

There is another brand of of castile soap that is widely available.  Kirk’s Castile Soap has been around since 1839.  Here are the ingredients: Coconut Soap, Water, Vegetable Glycerin, Coconut Oil, Natural Fragrance.  There is also an unscented version.

Being a relatively new fan of Dr. Bronner’s, and of course wanting a bottle in every single one of the luscious scents, I realized there had to be a better way.  Enter Liquid Castile Soap “Wonderful”.

The Master Recipe

This is so easy it is a wee bit embarrassing but stay with me.

Ingredients:

1 bar of castile soap
2 quarts (8 cups) of boiling water  (I used filtered water)

Equipment:

A large kitchen or vegetable grater
A bowl or pot large enough to hold 2 quarts

Directions:

1.  Using your kitchen knife, slice and dice the bar of soap into small chunks.  Or, if you are so inclined, grate it up with a vegetable grater instead.  Castile soap in inherently soft so there is no reason to drag our the food processor or blender to do this.

2.  Measure out your boiling water and place it your bowl, pot or do as I did and use a large Pyrex measuring cup.

3.  Add the chunks or flakes and walk away.  Go do something else.  Walk the dog. Catch up on Backdoor Survival.  Just do something. When you come back in an hour or so, most if not all of the soap will be dissolved into a nice concentrated liquid.  At this point, transfer your liquid castile soap to some mason jars, a squirt bottle or other container and you are ready to go.

Notes:

Within 24 hours, my batches of liquid soap turned gel-like and semi-solid.  A quick run under hot water brought them back to liquid form.  In a way, this makes sense because coconut oil does not liquefy until it reaches 76 degrees.  Given the tremendous cost savings, this was something I could deal with.

I tried both cutting the bar soap into chunks with a knife and grating it with my vegetable grater.  I felt that the vegetable grater resulted in a better end product.  I believe the soap dissolved more quickly and for some reason the resulting liquid was smoother.  I don’t know – hard to describe.

As will all castile soaps, there will not be an abundant amount of sudsing.  The suds in most soaps comes from sodium lauryl sulfates, a known irritant that does nothing but make suds. Be aware that you may get a few bubbles with this, but not many. Odd as it seems, it still clean very well and does not feel at all oily even though it is an oil based soap.

Those of you familiar with my Dirt Cheap Soft Soap will notice some similarities although there is no added glycerin in liquid Castile Soap Wonderful.  Castile Soap Wonderful has a completely different texture plus it is highly concentrated.

Castile Soap Wonderful

This is the fun part.  With a simple dilution and the addition of essential oils, I was able to make up multi-purpose household cleaners just like I do with Dr. Bronner’s.  The addition of 1/8 to 1/4 teaspoon of essential oils results in such a useful cleaner that I started calling them “You Name It” Wonderful.  I now have Tea Tree Wonderful, Lavender Wonderful, Orange Wonderful and Peppermint Wonderful.  This is so fun.

After much trial and error, I came up with the following dilution:

3 TBL Liquid Castile Soap
1 quart (4 cups) filtered water
1/8 to 1/4 TSP Essential Oils

Shake everything together in a repurposed bottle or juice jug and use your premade brew to fill individual spray bottles  (These spray bottles I purchased at Amazon work great.)

How to Use your Liquid Castile Soap

For the past three weeks I have been keeping a list of how I use my various castile soap wonderfuls.  Amazingly, I have I found that a single dilution, poured into a spray bottle, does it all.  So far I have not found any reason to use the soap undiluted or in a stronger or weaker dilution.

Household Cleaner:  Depending on your mood, pick your favorite version and spray away.  I use in on my black granite counters, wood floors, stainless appliances, everything.  The Orange Wonderful seems to work best on really greasy things which makes sense because orange essential oil is made from orange peels and we all know what a good solvent orange can be. (By the way, a drop or two of orange essential oil neat – right out of the bottle – works just as good as petroleum based goo gone.)

Window and Mirror Cleaner:  For some reason, my castile soap wonderful cleans windows and glass just fine and without leaving a residue while Dr. Bonner’s tended to streak on me.

Washing Hands:  Instead of using soap in the pump bottle, spray your hands with a generous amount of Tea Tree Wonderful, rub your hands together and rinse.  The tea tree serves as an effective anti-bacterial and sanitizer.

Body wash:  Spray your favorite scented wonderful on a washcloth and give yourself a “sponge” type bath.  (Does anyone even use that term anymore?)  Anyway, for extra moisture, you could add a bit of vitamin E oil or even olive oil to your spray bottle – just make sure you mark the bottle “body wash”.  While you are at it, add a few extra drops of essential oil so you smell heavenly.

Facial cleaner/facial wipes:  Spray your Lavender Wonderful on to a microfiber cloth or plain old washcloth and use it to clean off every bit of makeup, even mascara.  Your face will feel nice and soft afterward.

Toothpaste:  I kid you not.  Spray some Peppermint (or other) Wonderful onto a toothbrush and brush away.  I do prefer regular toothpaste but if there were non available, this would work just fine.

Eyeglass Cleaner:  Castile wonderful will make your eyeglasses sparkle.  Because you are cleaning with soap, you do not have to worry about ruining your Transitions lenses (never use a vinegar solution on them).

Clean fruits and veggies: Spay and wipe to remove gems and pesticides from non-organic produce.

Doggie Shampoo:  I used a combination of Peppermint and Lavender Wonderful for Tucker’s bath this weekend.  After wetting him down, I got out the spray bottle and sprayed away.  Are you detecting a common theme here?

Clean Your Shoes:  Spray and scrub.  My 5 year old Clarks sandals came out looking nice and fresh and ready for another summer.

Clean Makeup Brushes:  For those of you that wear makeup, spray your brushes every few days then wipe them clean with a microfiber cloth.  The bristles stay nice and soft and smell great.  No more built up makeup goo.

Dusting Spray:  I have been using this spray for three weeks on my wood furniture and most notably my desk which get very grimy.  I have also used it on my iPad and laptop screens and almost anything else you can think of.

One thing I did not try (but want to) is making a homemade soft scrub by combining 1 tablespoon liquid Castile soap and 1/3 cup baking soda in to a scrubbing paste.  Just thinking about it, it seems to me I could sprinkle some baking soda on my crusty pan or gunky sink and just spray and scrub without making the paste.  Even though it only costs pennies, using an undiluted tablespoon seems wasteful.  Again, I have not tested this.

I am sure there are lots and lots of other uses – these are just the ones I have tried.

Magic versus Wonderful

In the past I have referred to “Rose Magic” and “Peppermint Magic”.  The only difference between Peppermint (or other) Magic and Peppermint (or other) Wonderful is that “Magic” uses Dr. Bronner’s and “Wonderful” uses the DIY liquid soap make with Kirk’s.  Same dilution, no difference.

Credit Where Credit Is Due

There are lots of websites that have similar instructions but as you will find, everyone has their own dilution and their own way of doing things.  This is my way and it works for me so I have a high degree of confidence that it will work for you too.

The Final Word

Shop around and you might find a deal on Kirk’s bar soap.  I initially picked some up at Safeway when I was in the Seattle area but by far, the cheapest place I found online was at drugstore.com.  I paid $3.79 for 3 bars and since I also purchased some other products, shipping was free.  I am told that some Wal-marts carry Kirk’s at a similar price so it is worth checking locally.

I have now stocked up on Kirk’s and will put some in deep storage.  At this price, having the ability to make my own scented liquid castile soap any time I want to sounds like a good proposition.  Not only that, I am convinced that being armed with vinegar, castile soap, spray bottles and microfiber cloths, I can clean anything!

Enjoy your next adventure through common sense and thoughtful preparation!

Bargain Bin:  Below you will find many of the items mentioned in today’s article.  As always, check your prices and for heaven’s sake, don’t get tricked into buying a single bar of of Kirk’s castile soap for $5.

Kirk’s Original Coco Castile Bar Soap:  This is a great price at $3.79 for 3 bars from drugstore.com. iconAmazon also sells Kirk’s here – Kirk’s Castile Soap Original (3pk) .

Amazon Basics Microfiber Cleaning Cloth, (Pack of 36): I just noticed that Amazon is selling their own brand of Microfiber cloths.  They are not as “fuzzy” as the Z-wipes.  I have both types.  Whatever you choose, they will last for years and will allow you to replace paper towels forever.  I color code using green for glass and windows and the other colors for everything else.

NOW Foods Peppermint Oil: I favor peppermint essential oil (okay, I like Lavender essential oil  too) so this is what I get.  There are many types of essential oils to choose from.  Take your pick.  One thing you will find is that a little goes a long way.

Soft ‘N Style Clear Spray Bottles I happen to like these smaller bottles and you can not beat the price for a set of 6.  Likewise for these Pump Dispensers.

Box-style Hand Grater:  As easy as it was to use a kitchen knife, it just felt “better” to grate the bar soap by hand using an old fashioned grater.

  1. I made this this morning. Bought distilled water for this but used tap water we have a water softner. It is milky but the consistency of water. Hoping it will thicken up by tomorrow. Havnt recieved the essential oils in the mail yet but dilluted this cleaned the living room windows the tv screen my glasses the range hood ect. Seems to work well. Ill be glad when i get my sweet orange oil for a degreaser. How would yuo use this as shampoo? Our grandson has gotten head lice at school and I’m going to make teatree and peppermint just use about a tea spoons worth?

  2. Oh my goodness….I love this stuff!! I made this today and used lemongrass essential oil. I am using it as laundry aid for my hubby’s stinky biking jerseys. I just spray the underarm/neck areas really well, throw it in the laundry and BAM! Smell is gone!!

    • I checked and each bar is 4 ounces. Hope this helps and that you find something comparable. If the bar you find in a difference size, you can always adjust the amount of water. I will also respond online.

      One suggestion is that you can use a bar of Dr. Bronners Soap. I have not tried it but that should closely mimic the liquid.

  3. I use Kirk’s Original Coco Castille soap as a body bar & just ordered more today from Walmart online. It’s $3.28 for a 3 pack of 3 oz. bars. Tough choice – Dr. Bronner’s at $14-$16 / qt. or approx $1.09 per 1/2 gal.! I do keep an ongoing Walmart list & wait until I can spend more than $50.00 to get free shipping. In fairness to Dr. Bronner’s, it is VERY concentrated & lasts a long time but I like to DIY where I can. Thanks again – perfect timing for me!

  4. I heard that Tea Tree oil should not be stored in plastic, that it will eat it, including the lid. Is that true? Maybe in such a diluted amount, it’s not a big deal?

    • Pure essential oils that are not diluted should be stored in glass but if used in a potion, salve, or cleaning product, they will be fine. I have never had a problem and do it all of the time.

  5. I have a bar of goat milk soap (olive oil, coconut oil, Palm oil, mango butter, fresh raw goat milk, sodium hydroxide, fragrant oils). It smells like lilacs. Since it is primarily made of oils like a castile soap, but lacks the glycerin of Kirks, I wondered if it would work to make liquid Castile. Has anyone tried this recipe with Castile soap other than Kirks and had success? Or should I stick with the dirt cheap liquid soft soap? Please let me know!

  6. Hi I want to make body washing gel for bathing yet there is no castille soap in my neighborhood in Kenya… Please help. What is a substitute for this soap?.

    • Agnes – Try this “recipe” that uses any type of soap that you wish. (I used those small bars you get when staying in hotels. It makes a lovely soap.)

  7. This is exactly what I have been looking for! lol Everything I find wants to use this soap for washing hair or body but I was wondering about cleaning everything else. I love my Dr. Bronner’s and the company has such a good message I want to support them but I also love saving money. I think I will go forward as planned making Dr. Bronner’s bars into liquid castile soap. Thank you! <3 Since I am wanting mine farely liquid I am thinking 1 bar for 1 gallon of water and then I can put it right back into the bottle.

  8. I made this yesterday, using one 4 oz bar, and reverse osmosis water. 2 quarts of water. Boiled for 5 minutes and let sit undisturbed for 24 hours. It’s very clear and thin. I was curious why you said at the beginning that you get a quart of liquid castile soap for under $1.49, but your recipe calls for one bar of soap and two quarts of water. It doesn’t lather much, but if the dilution is more…..open for suggestions….

    • Lucinda – I tried to find my original notes but they are long gone. You are the first one to catch this. I will make another batch and try to figure this out. My guess is that 1 quart of water was not enough so I added another.

      Regarding the fact it is thin: How warm is your home? I keep my home very cool (65 degrees) which accounts to the gel-like texture. Also, the minerals in the water (or lack thereof) will result in differences in the final product.

      You can try adding another half bar of castile soap to thicken things up but I would attempt to use it as is first.

    • Don’t do a thing!! Just change your quart comment to TWO quarts. Let me tell you why….I poured my soapy “water” into a half gallon jar after 24 hours, shook it a little bit, and wrote my post above. Got up the next morning, and noticed my previously crystal clear half gallon jar was turning cloudy….gave it a little shake, and noticed it was thickening up a little bit. Fast forward another 24 hours, and I have a half gallon jar of opaque soap gel. Used my cookie scoop to plop a scoop into an empty foaming hand soap bottle, added a drop or two of citrus blend essential oils, shook them together, added water, leaving enough room to shake/blend together, and now have a very nice bottle of foaming hand soap. Time was all I needed to see it come together, and I am so very pleased! Thank you!!!

  9. I’ve made soap from scratch (for a science class I taught) using animal fat (hard soap)/vegetable oil (softer soap) and sodium hydroxide/wood ashes, using the ratio: 2 parts water:1 part lye, 0.38 parts lye water:1 part fat (by weight; ie. 6oz lye water to 16oz fat). Before you get started, you MUST wear gloves and goggles to protect yourself. You basically dilute your sodium hydroxide in a glass container by slowly adding the sodium hydroxide to the water while stirring (when diluting strong acids and bases, add the water to the container first then very slowly add the acid/base – this minimizes the chemical reaction because the excess water absorbs the heat that is generated, doing it the other way could lead to a violent reaction/explosion). Heat the fat while stirring (especially solid animal fat) at low heat to begin to dissolve and slowly add the alkali sodium hydroxide water solution. It is important to use the ratio above, if you add too much sodium hydroxide, there will be excess in your soap – which will irritate and damage your skin (the only way to remove acids/bases from your skin is to rinse your skin with a copious amount of water to remove most of the acid/base and then neutralize them with a mild counterpart base/acid; sodium bicarbonate (baking soda) works well for acid neutralization and vinegar/lemon juice works well for base neutralization. The mixture will eventually form a paste, at which point you can remove from the heat and store in fragrances and other oils, if you desire. Lastly, fill molds with your hardening soap to make bars. Have fun!

    On a completely separate topic, have you thought about making a backup copy of your website or compiling all of this useful information into a PDF or similar file, should we lose power for good/an extended time period? It would be great to be able to go back to this information via a laptop or other battery powered device. Thanks for all the useful information.

    • You are not the first to suggest a backup copy or even a DVD with all of the pertinent articles from Backdoor Survival. I have looked into authoring tools and as far as I can tell (and I am not an expert at such things), each article would have to be added to the archive individually. That would be a huge, time-consuming effort.

      As it stands, I try to spend an hour or two each week cleaning up old articles that need to be updated and reposted because they are lost in the archives. This is very slow process and I have been unable to meet my goal of 2 per month. I also need to go back and set up more relevant categories and then set up category archive pages.

      If anyone knows of tools that would allow me to easily put articles into a PDF or DVD, I would love to hear from you.

      PS – I would also like to put some of the DIY articles on YouTube but lack the time to figure it out.

    • Could you not just copy and paste the articles into Pages, and then select Export to PDF? Then you just save them in a folder on your computer.
