How can I remold soap out of old soap scraps?

My former mother-in-law showed me how when she would get a really thin piece of soap left from a bar, she would wet the new bar and the small piece, while in the tub or shower, and stick them together firmly, then while still in the tub or shower, smooth the edges down all the way around the small piece of soap. You didn't get a new bar that way, but the small piece didn't go to waste either.

When I have a lot of soap scraps saved up, I grate them on a coarse grater into a bowl. Then I add just enough water or liquid soap to make it stick together like clay. Once you have done this you take a handful of it and form it into one or more bars of soap. I make mine an oval shape. Let it dry a few days and then it is ready to use.

Grate or cut the soap into small pieces and place in a microwaveable bowl about 3 times larger than the amount of soap. Add vegetable oil (abt 1 T to 1 cup of soap pieces). Sometimes I add cinnamon (about 2 t, other spices can be added such as basil, chopped bay leaf, etc.), oatmeal (about 2 T per cup) or cornmeal for texture, aroma, and to act as natural scrub.


Add about 1/4 water. Heat in 1 minute increments at 50% power (the soap expands and you don't want to make a mess in the microwave). Stir. Repeat until the soap is soft. Sometimes I leave coarse bits of soap in the mixture to act as scrub. If you accidentlly use too much water, add more liquid to create a liquid soap, or add more oatmeal for a more density.

For soap bars or balls, the mixture needs to be the consistency of playdough. Dump the soap onto wax paper and mold. Pull the wax paper off the top of the soap Let sit a couple of hours, then turn the soap over so the bottom can dry out. It should be ready to use the next day. Soap balls will take longer to cure.

I made new soap using scraps and some body oil. The soap is not setting. Any clues to fix the problem please?

Make sure you are giving the soap enough time to dry. Initial drying is a week, and secondary drying can be 3 weeks.

Normally, if you are trying to make new soap out of soap scraps, you shouldn't add oil to the mixture. This can prevent it from setting and drying. Furthermore, it can take several weeks for the soap to dry.

What is the easiest way to make a new bar of soap from all of my old soap scraps?

Making a Bar of Soap from Soap Scraps


I'd chop them all up just using a big chefs knife on a cutting board, then put them in a piece of fabric - just a cotton scrap. Then soak it in hot water for a minute and when you take it out, press it all together. Set it aside and let it dry. Once it's dry, just take the cloth off and you have a new bar. Of course, you could do this without chopping them up first - just mush them together in the cloth and hope they stay put. (03/12/2007)

Save up 11 ounces, making sure they are dry. Use your grater to grate them up. Put them in a sauce pan with 8 ounces of water and bring to a boil, stirring constantly. They should blend together like a smooth pudding. Pour into molds. Our daughter uses the bottom parts of water bottles to make a cute, flower-shaped one, or use any flexible plastic mold. This should make about 3-4 medium-sized bars.


After they are set up, pop the bars out of the molds. If they don't come out easily, stick them in the freezer for 4 hours or overnight, or until they feel dry when you touch them. Then they will pop out easily. Air dry them without their touching each other for 2-3 days. As Mammy Yokum would say, "Abber Ka Dabber." (03/13/2007)

I have an apothecary jar with the rubber seal lid that I drop leftover soaps in with water and they melt and become creamy. Then add mouthwash to it if the slivers aren't antibacterial so it will kill germs, and it will thin out enough to add to a pump bottle for use :) (03/13/2007)

I found the best way is to chop up and use a little water and form a new bar or any shape you want, but you must let dry or it will melt when you go to use it. (03/13/2007)

Making a Bar of Soap from Soap Scraps

Here's a really lazy way: find a pair of old clean knee-high hosiery; slip one inside of the other; drop in the old soap slivers; use to lather up a washcloth as you would a bar of soap. Hang in shower to drip dry. They also tend to "congeal" together after a few uses. (06/03/2008)

How can you make soap from old soap and soap left overs from soap carving?

By PETER from Loscoe, Heanor, Derbyshire


Making a Bar of Soap from Soap Scraps

Grate all of the soap leftovers. Slowly start adding small amounts of water until the mixture can be mixed into something very similar to sticky Play Doh. I haven't tried it, but have read that at this point you can add one drop at a time of essential oil until you get the desired scent.


When you reach sticky Play Doh consistency, form the soap into balls by rolling the desired amount between your hands or press into a cookie scoop. Set on a cookie rack to dry. If no cookie rack is available, put on wax paper and turn at least once a day until dry. (08/11/2010)
