How To Make Castile Soap

I have been on a quest to make cheaper things for my house and it was on my list to learn how to make Castile soap – the liquid version.

Just in case you didn’t know, Castile soap is natural and free of toxins! Plus, it’s environmentally friendly. Now, who doesn’t love that?!! So I needed to find something just as natural on how to make Castile soap – the liquid version.

Normally, the liquid Castile soap bottle that I buy is $10+, and I really wanted to find something cheaper. $10 is a lot of money for one item!

As a busy momma, I needed the process for making Castile soap, easy and fast. My time is filled to the brim already.

How To Make Castile Soap


You’re going to be pleasantly surprised, how to make castile soap is very simple.

First, you need to grate the Castile bar soap. You can use a food processor or a cheese grater. I was tempted just to cut it up into small chunks, but it really needs to be more “flaky” so that it will melt quickly.

Add the grated soap to your glass bowl.

Then, add the almost boiling water into your bowl.

Stir until the flakes are dissolved with your metal or plastic spoon. It is important not to use wood as the wood would absorb the soap and then you would not want to use it for cooking.

Let the soap mixture sit to cool for about 4-6 hours.

Once the mixture has cooled, transfer your liquid castile soap to your glass or plastic container.

Make sure to label the container to prevent accidental consumption.
