How to Make Soap Using Leftover Soap Pieces was something that my husband and I wanted to try. We were constantly tossing out those little soap pieces and soap is expensive. We played around with our soap making skills and finally found this simple way of making soap.
In this tutorial, I’m going to show you how to make bar soap from these little pieces. So start saving all of your leftover soap.
Step 1: Throw all of the soap you have in your blender.
Continue to blend it until your soap is in tiny pieces.
Step 2: Over medium heat add a 1/2 cup of water and dump all of your soap into a medium sauce pan
Step 3: Stir your soap. At this point depending on how much soap you used, you may need to add more water. Continue to add some more water until the soap starts dissolving and becomes a cake like batter.
Step 4: Reduce heat to low and cover. Stir frequently until soap thickens.
Step 5: Using a muffin pan, spray the tin with oil. (Any oil is fine) Then pour the soap batter into the muffin tin. Or use a fancy soap mold.
Step 6: Using a spoon, smooth out the soap batter.
Step 7: Let sit overnight, or place in freezer for a few hours until soap hardens and when done your soap should look like this. Then wrap your soap with plastic wrap and that’s it.
You can decide how big you want your soap by using various containers. We actually preferred our muffin tins because these soap pieces actually fit right into the palm of our hand.

Love the step by step photos for making your own soap from all those little bits! We mostly use body wash, but if I do use bar soap, I’m a bit obsessive about using every last bit. I can see this being very handy!
Wow man this is lovely can’t wait to try this thanks so much
You could even turn it into liquid soap by adding more water. I do love this idea of turning them back into bars though. I found you via I Should be Mopping. I would love for you to visit my little cleaning blog here.
Angela that’s so funny you mentioned that because I’m currently making body wash with our left over soap to show what else you can do with left over soap pieces.
OMG that looks so easy! Thank you I’m gonna try this! Sharing too!!
It was so simple. Making Body Wash from it was easy too. I’ll have post up soon on how to do that.
What a great way to recycle. I am going to start saving my left over soap and give this a try. Thanks for sharing.
I don’t go to all that trouble. I just put the left over pieces in an old liquid soap container with some water. The soap will eventually melt, just shake it before you use it.
Nice! What a great and simple tip!
I have made soap a slightly different and easier way, I take left over small bath soap pieces and put them in a sandwich bag and crush them with a meat tenderizer hammer, then place the soap pieces in a paper cup half way up, fill with water half way up, put the cup in the microwave for a minute, then place cup in freezer for an hour…then take out and run under cold water, the cup separates out from the soap.
Thanks for sharing! I love your technique and how everything you use (besides the meat hammer) is disposable.
Using water always makes the soap crack for me i just melt and mold
I learned a long time ago that soap sticks to soap if both pieces are wet. Every time I get to the last small sliver of a bar of soap, I get a new bar of soap wet and somewhat warm by being used in the shower or tub, then I take the old bar remnant and press it to the surface of the new bar. I try to fill in the edges of the old remnant by rubbing with my hands until some soap fills the joints. Then I leave it to dry until my next daily shower and the two soap pieces have become one. I can then use up the remnant on the back of the new bar.
Oh what a clever, I did do that many years ago, but I didn’t press the old bar remnant firm enough and only used a dab of water no wonder, thanks for the tip BB
Finally I can use my soap pieces. Thank you for this Tutorial.
I have done this for several years… rarely have to buy soap any more. Tip …get it really hot when cooking or add a bit of bleach, in order to kill any germs. Also, let it dry well and there is no need to wrap it, and the soap keeps longer, l keep it in a box in a drawerwith a face cloth under and over it. Nice to see other people doing this.
Hello, Finally! After browzing Pinterest for leftover soap ideas I came to yours. I don’t have to buy anything but spray oil but I’m going shopping today. I want to make these homemade soaps for my family who my daughter lives in Florida, my son and his family in Texas. I’m excited:)
I have wanted to do something with my leftover soap for a while now. Finding this sounds great but I do have a concern. This may sound silly but could there be an issue with bacteria with previously used soap?
I’m not sure. I would think that cooking the new batch will kill existing bacteria.
I followed this but after freezing it and taking it out, it gets really soft within minutes. I can’t get it to harden. Suggestions??
You might want to try using less water. Hope that helps!
Wow way cool, I had been thinking for some time now (1-2yrs lol) to make me some soap from my left-over bars, I thought of it again this afternoon, so put fingers to keyboard and hustled up this site, it was the first on the list .. I’m not using my blender no way, I have another way to hack them to bits and I ain’t using my cookie trays either Oh I went back to take a look what tray is it well I don’t make muffins but I should thanks for the idea Lol;P, I’ll make my own moulds, when I thought about it today how to make soap, I knew a mild heat would be involved, just so simplistic and straight forward, thanks for the heads-up on how to make a cake of soap ..
bacteria are everywhere, hell they’re even on our sandwich when we take a bite, the Heat kills them so there’s no real concern, however if one has sensitive skin and or is allergic, then .. Simple don’t make cakes of soap
