Pick out a bar of soap to use.
You can make liquid soap from any bar of soap you have around the house. Use whatever leftover or half-used bars you have, or put some extra thought into your choice to create a liquid soap you can use for a specific purpose.
For example:
Use a bar of facial soap to make a liquid soap you can use on your face.
Use a bar of antibacterial soap to make a good cleansing hand soap to use in your kitchen or bathroom.
Use a bar of moisturizing soap to make a liquid soap you can use as body wash.
Use unscented soap if you want to add your own scent to create customized liquid soap.
Grate the soap into a bowl.
Use a fine cheese grater to grate the entire bar of soap into a bowl. Use the finest grater you have so that when it’s time for the soap to melt, the process goes more quickly.
You can cut the soap into chunks if that helps you grate it more easily.
You should end up with about 1 cup (229 g) of soap flakes.
If you have less, grate a second bar of soap.
This recipe can easily be doubled or tripled if you want to make a lot of liquid soap.
It makes a great gift, especially when it’s stored in pretty jars.
Blend the soap with boiled water.
Boil 1 cup (235 ml) of water, then pour into a blender along with the grated soap. Whip the water and soap until it takes on the consistency of paste.
Making soap in your blender may leave a residue that’s hard to clean out, so if you’d prefer not to use it, you can make your soap on the stove instead. Simply add the soap flakes to the water once it has started to boil on your stove.
Try making soap in the microwave as another alternative.
Place a cup of water in a microwave-safe dish, bring it to a boil in the microwave, add the flakes, and let them sit for a few minutes to melt.
Place the dish back in the microwave and heat it up in 30-second increments if it needs more heat.
