When it comes to making your own cleaning products, beauty products and household helpers, one thing that is often called for is liquid castile soap like Dr. Bronner’s. Usually people are shocked by the price of it and get turned away from buying it and thus, give up on doing things themselves, While it is true that Dr. Bronner’s is often expensive, it is kind of relative. Since Dr. Bronner’s goes a long way and is concentrated, it really is, use-for-use, very low cost compared to what you would spend on store bought cleaners and beauty products.
However, if you are like me, you just know there is a cheaper way to do just about anything and castile soap is no different. Turning a bar version of castile sopa into a concentrated liquid is very easy and take little time or extra ingredients.
I found the cheapest way to do this is using Kirk’s Castile Soap. It is around $1.25 a bar and is often bought in packs of three. I found mine at Fred Meyer for just over $3 for all three bars so this had me all kinds of giddy.
You can also order Kirk’s Castile Soap online if you cannot find it in a store near you for a bit of an increase in price, but still much cheaper than Dr. Bronner’s. This soap concentrate can be used in any recipe that calls for liquid castile soap, but since it is so concentrated, use a little less. For instance, if you are making my soft scrub recipe, use only 2 tbsp as opposed to 3 1/2.
Kirk’s Castile only contains a couple ingredients so I love how natural it is and it smells great, too!
How to Turn Bar Castile Soap into a Concentrated Liquid
- 1 Bar Kirk's Castile Soap
- 3 Cups water
- 2 Tbsp Glycerin
- Start by boiling the water in a tea kettle.
- On a cutting board, cut up the bar into small chunks. You want them as small as possible. You could also grate it, but I find cutting to be much faster. It cuts really easy and is not hard.
- Place the soap in a glass bowl or container. When the water boils, measure out just under 3 cups and pour over the soap.
- Give it a good stir and let it sit, covered for about 20 minutes. Every once in a while, go give it another gentle stir to make sure the chucks all melt.
- At this point, add the glycerin. The glycerin will help it stay more liquified as opposed to a gel.
- When all chunks are melted, pour into a glass mason jar, label it and you have your liquid castile soap!
