I’m sure you’ve seen how much money you can save when you make your own products using liquid castile soap.  Or that you can make so many homemade products with liquid castile soap that you’ll stop buying hand soap, dish soap, laundry detergent or even shampoo at the store. 

While there are so many benefits to using liquid castile soap, it can come with a larger price tag than I would like to pay.  I know over the long run that it’s cheaper than buying store bought items to make your own.  But, I also know that you can buy castile soap bars really cheap online or in grocery stores.

Making hard soap into liquid

I started searching online to see if there was a way to easily turn bar soap into liquid soap.  Turns out, there were multiple ways to do this.  I wanted it to be simple and easy, with kitchen equipment that I have on hand (not the immersion blender that I don’t own).  I read several articles about the “right” way to do it and decided to try it my own way.

The hard soap needs to get hot enough to melt, then hot water is added to it.  The two are blended together and then allowed to cool before being put into a storage container. 

The soap gets hot the fastest when chopped up into smaller pieces.  To do this, I grated my bars of soap using the large holes of my cheese grater. I grated them directly into my crock pot.

Once in the crock pot, I added six cups of HOT water.  Like, steaming hot water.  Then I cranked my crock pot on high.  After an hour, the soap was melted.  I stirred the two together with a whisk and turned my crockpot off.  I pulled the pot out of my crockpot and let it cool on the counter for about an hour. 

I wanted to make sure that it was really going to stay liquid before I poured it into my gallon plastic jug that I was planning on storing it in.  After an hour, it was cool enough to handle and was still completely liquid.

Using a funnel, I carefully poured the newly liquid castile soap into the plastic jug.  A week later, and it’s still completely liquid! 

Why use liquid castile soap?

As I mentioned before, there are a ridiculous amount of recipes online for making household cleaners, detergents and even products like shampoo or body wash using liquid castile soap. Castile soap is made from olive oil.  There aren’t harsh chemicals in it, and it’s way more natural than over the counter cleaners.

Dr. Bronner’s is the brand that comes to mind when I see liquid castile soap.  This is the brand that usually comes with the more expensive price tag.  Don’t get me wrong, Dr. Bronner’s liquid castile soap will last a long time and is a good value, but if I can make it myself and save a little money, I’m going to.

That’s when I noticed that you can purchase hard bars of castile soap cheaply and make liquid castile soap at home. The hardest part about making the liquid soap was grating it.  I grated three bars and, even though it grated easily, my arms got a workout!  You could definitely chop the pieces up with a knife and just put them into your crockpot.

Putting the soap in the crockpot was easy and didn’t lead to a huge mess. The crockpot was super easy to clean afterwards, I guess from all of that soap! 

Spend a few bucks and buy some castile soap bars.  Turn them into liquid and start having fun making your own cleaners, foaming hand soaps, laundry detergents and shampoo.  You’ll save money and feel better about the products you’re using on yourself and your home.
