How to Make Liquid Soap From Leftover Bar Soap Slivers

If you use bar soap, you know what happens when the bar soap wears down to a small sliver; it usually gets thrown away. You do not have to waste these soap slivers though; you can save these to make liquid soap. This is a great way to utilize the leftover soap that usually gets thrown in the garbage.


  1. Save all of the slivers of bar soap that you have. Once the bar soap gets to a small and unusable size, place it somewhere to dry out.

  2. Place all of the bar soap slivers that have been allowed to dry out into an airtight baggie until you have saved enough of these to make a batch of liquid soap. You will need to have at least six to twelve slivers to make a decent sized batch of liquid soap.

  3. Place the slivers of your bar soap that you have saved into your blender. You should add them a couple at a time and then blend in between so that the slivers are properly blended.

  4. Add a small amount of water to the bar soap that has been blended, and then blend it together with the soap for about 15 seconds.

  5. Add another small amount of water and repeat the process until it has reached the desired consistency.

  6. Empty the now liquid soap that you have made into an empty liquid soap container. If there is more than enough to fill a standard liquid soap container, you can store the excess in an airtight container until you are ready to use it.

  7. Wash out your blender thoroughly so that you remove all of the soap residue from the blender. You do not want you next milkshake to have the aftertaste of your bar soap. You may want to wash it out more than once to ensure that it is thoroughly cleaned.
