DIY – Making a gallon of liquid soap for $4

Things I love:

Saving money
Yummy smelling things
EASY projects

This DIY project was perfect for me! I took 2 bars of soap and made them turn into more than a gallon of liquid soap! So awesome. The two bars of soap were $2.99 together and the glycerin was $1.19.

What you need:

A grater
2 bars of soap (I used pomogranite rose… so good!)
2 tablespoons glycerin (get it in the medical aisle. weird, I know! here’s some online)
1 gallon water
A big ole pot


What to do:

1. Grate all the soap
2. Put all “ingredients” in the pot. (2 bars grated soap, 2 tablespoons glycerin, 1 gallon water)
3. Put stove on medium until all the soap is dissolved
4. Turn off stove and let it be for 10-12 hours. After a couple of hours it will harden a bit and turn cloudy
5. Pour it into an empty milk carton, an old “refill” soap container, reusable soap dispensers, a beer growler (WHO would do that?! Oh right, we did.)

All soaps are made differently – if yours is too runny, remelt with more grated soap. If it’s too hard, add more water.

And you’re done! Super fast and now you’ll have soap forever. Enjoy your soap!

    I have made this twice and it has comes out witht his goopy texture and it does not really foam when you use it. Any ideas how to make is smoother and more foamy

    Is this recipe for hand soap or body wash? Or, both? I noticed one person’s recipe said to use dish soap – I can’t imagine using dish soap on my body. Just wondering. I’m interested in alternatives and want to learn. Thanks!

    I use the same recipe basically, but I always boil my water first to remove bacteria and other nasties in tap water. The soap disolves more quicky too. I have used the off brand at K Mart for the Dove unscented, and it came out fantastic! Now I can add EO to individual bottles, and have total control over scent and ingredients. I have also had good luck using Kirk’s Castile, but it took 2 days to thinken up! Worth the wait tho! Thanks for posting this!

    Do I cover the pot while it is “sitting”?

    CINDY!!! Guys, Cindy is a genius. My family and guests complained about my watery, stringy, homemade liquid soap, but Cindy’s idea about a bar of Dove and 2 cups of water is PERFECT. I got a lot of Dove bar soap on sale once, and now I can make hand soap everyone loves for only 5c per ounce. This is much more expensive than the glycerin recipe, but for something homemade to work in my house, it actually has to function as a good replacement for its store-bought counterpart. You don’t even need to let it sit for hours before pouring the luxurious creamy soap into soap dispensers. Bravo, Cindy, for a savings experiment my whole family will thank me for!
