There is an episode of the Simpsons where Lisa, in an attempt to save her family money takes all the little leftover bits of soap and creates a chimerical ball of soap. Not only is it a funny joke, but it is a good way to save money and reduce waste.

How to Make New Soap from Old Soap


To recycle your soap scraps into new bar soap, place 2 cups of grated soap scraps in a saucepan and cover them with water. Let them soak for 24 hours, giving them a stir every now and then. Next, bring the pan to a boil, remove it from heat and add a tablespoon of vegetable oil for each cupful of soap soup. Pour the mixture into molds?milk cartons work great. After they've hardened, you can cut them into smaller bars, but let them cure for two weeks before you use them.

Perhaps you don't have the time or the energy to create a Frankensoap. So I'll offer up a few more suggestions.

Other Ways to Reuse Those Leftover Soap Bits

1. Mix the old soap with glycerin. Melt in the microwave. Use as hand soap.

2. Put the soap bits in an old sock or a cloth bag. Hang the cloth bag from the shower head. Wash yourself with it like soap on a rope.

3. Soap can be used as tailor's chalk.

4. Make laundry soap

The recipe I have calls for 16 cups baking soda, 12 cups borax, 8 cups grated castile or glycerin soap flakes, 3 tablespoons essential oil. Use 1/8 cup per load. I thought I'd save my old bits of soap to make my own soap flakes?save up until I had enough to grate 8 cups in my food processor.
