Reforming Soap Scraps





Introduction: Reforming Soap Scraps

Many people buy bar soap in bulk, but the money you save often gets tossed when you stop using the scraps. Everyone does it. I got sick of throwing money in the trash and decided to start saving the scraps of bar soap. I melt them down once a quarter or so in a small saucepan and form a few new bars of 'mystery soap' that I then use just like normal soap. Beats ending up in a landfill. Here's how I did it.

Step 1: Collect the Soap

Save the soap scraps. I toss them into a drawer in my bathroom and wait until I have about 20 slivers of soap scraps. Personally, I use Ivory and Irish Spring, but you'll also find some Lava scraps in there too. Your preferences may vary, and you may want to separate them out if you're looking for consistency in the bars you make. Me, I don't really care.

Step 2: Break the Soap Slivers Into Small Chunks, Add Water

Break them into small pieces, about the size of a quarter, and then add about enough water to be visible at the level that the soap slivers are at. Turn on the burner to medium heat.

Step 3: Boil, Gently

Avoid boilovers, but simmer for a few minutes. The goal here is to get the water and the soap hot enough that they begin to stick together. They will, trust me. Stir often.

Step 4: Pour Into a Steel Colander

I put a frying pan underneath the colander so that the soap dribblings are captured and not wasted. Use a wooden spoon to push the soap mess around the colander so that the majority of the excess water is drained. You're trying to get a molten soapy glob, basically.

Step 5: Grease Two Small Glass Bowls

This makes it much easier to extract the soap 'bars' afterwards. Continue to let the soap mess cool and drain for a few minutes.

Step 6: Form Bars in the Bowls

Using a spoon, gather half the warm soap matter from the colander and stuff into a bowl. Repeat with other greased bowls as needed.  I dump the captured soap dribblings from the frying pan into one of the bowls that needs more soap matter - this one usually ends up being the 'fluffiest' soap. Clean up (this part takes the longest, in my experience), and place in the refrigerator overnight.

Step 7: Liberate the Soap From Bowls

Use a steak knife - slip it between the cooled soap matter and the glass bowl - it should pop right out with a little twisting. Use the recycled soap immediately or store it for the next time you (or mankind) runs out of soap.

    I used some of my candle molds and it worked great. Also used some of the candle making techniques, such as chunks of different color dropped into base soap, or swirled into another

    I just stick the used bar to a new bar of soap once it gets too small to use, no waste, no mess, no problem.

    I've tried sticking old small bars to a new soap and it doesn't stick too well for me.

    for those saying you just stick the old soaps to a new bar ....... get that we aren't stupid , but this is something people like to do when they want to mix a bunch of different ones together to create a very great smelling kick a** soap , especially when your scraps consist of so many variations like deodorant soap , glycerin bars , soaps with moisturizer (oil of olay) , samples from hotels or department stores many that when put together can turn out to be an amazing bar of soap!!

    I use a microfine grater (zester) to make soap dust. Then all you have to do is add a slight amount of water to the dust, stir it up, and put it into the mold. No heating involved.

    I really like this do you have a recommendation on the grater to use?

    Back in 2007 the MicroPlane brand was the only one that had a zesting quality blade. I believe there are others now. Look for the finest grater you can get at Bed, Bath, and Beyond.

    If you have or can get a meat grinder it works super well to grind the soap ends into powder. I have a manual one with a crank that I'd recommend over an electric one - more control and easier to clean since it completely disassembles. Thanks for the tip about powdering the ends!

    I've often wondered if you could remold soap. I was thinking of molding it in a mold with a custom family crest or something.
    If you just want to avoid wasting the soap, why not just put a few pieces in a cloth bag and use it to wash with?
