How to make Hand Milled Soap

Not long ago, I finally took the plunge into making my own soap. I was so nervous about using caustic materials like lye: what if I spilled it and burned my skin?! Eventually I got comfortable enough with the process that it’s really not a big deal any more.

I even shared my soap making secrets with you a few weeks ago! Hot-Process soap is my go-to for ease and quick use. The recipes are simple and there is a lot of room for creativity!

One of the reasons for getting into soap making was to start selling quality herbal soaps. The other was to limit the chemicals we use on our bodies and to save some money in the process.

There is a little bit of investment on the front end, but handcrafted soap can be a huge money saver. And I’ve got another idea for you to stretch your dollar a little farther.

Have you ever heard of Hand-milling? Hand-milling is the process of melting down soap scraps and creating an entire new loaf of soap!

You know those little scrappy pieces of soap that no one really wants to use up and get stuck to the corners of the bath tub? Save them and make new soap!

The hand-milling process is very simple and very frugal. Keep reading and I will walk you through it.

The Hand-Milling Process

If you want to make a full loaf, you need about 1 lb of scraps. When your soap reaches scrap level, remove it from the shower and let it dry completely. Store it in a container with your other scraps. It doesn’t need to be air-tight, the air will just continue to dry it out a little more.

Also, if you make your own hot-process soap, save the scraps from your crock-pot. Those are perfect for making hand-milled soap! I use a dish scraper to get the bits out of my crock-pot after it’s cooled down. The scraps go into recycled jars until I have enough to make a new loaf.

Once you have enough soap scraps, chop them up or grate them into small pieces. The smaller the better so they will melt quickly. (I did not quite get mine small enough the first time and it took quite a while.)

Set up your double boiler (or two pots stacked together) with water in the bottom and add your soap to the top. Add about 8 ounces of water per 1 lb of soap. If you are using less soap reduce the amount of water.

Get the bottom boiler water at an easy roll, not raging; you don’t need the soap to get too hot. Stir occasionally as the soap melds together and the water is absorbed.

While the soap is melting, line a loaf pan or soap mold with parchment paper. You don’t want to put soap in a mold without a liner. Its crazy hard to remove! (Trust me I know!)

Once the soap is melted, you can add in some essential oils if you would like a new scent. My old bars consisted of Peppermint and Rosemary scent so I added in some Cedarwood which paired nicely with those two.

Scoop the melted, scented soap into your mold and press down with the back of a spoon so the top is somewhat smooth. Place your mold into a cardboard box and cover with a towel. This ensures that it doesn’t cool too quickly causing cracking on the top.

Leave your soap in the mold for 24-48 hours. (Sometimes it needs more time if you live in a humid climate.) Once you remove the soap from the mold slice into bars. If the bars seem soft, store in the cardboard box with the bars standing up with some space in between. This gives them air flow to dry them out a little bit.

Since this soap was already cured the first time it was made, it is ready to go! You now have fresh bars of soap made completely from old bars! You didn’t waste your handcrafted soap, and you were super frugal by utilizing resources you already had on hand.

Even if you don’t make your own soap or shampoo bars, this method works great for any type of soap. Handcrafted soaps are often the best for you since they won’t contain any harmful chemicals, but they can be pricy. Being frugal in your use and reuse makes an impact on your budget!

I love using my handcrafted soap and am very excited to make it last even longer.
