How to Make Natural Luffa Soap Bars

The Luffa Soap Sponge Bar

Also called: Loofah and loofa, the amazing luffa gourd can be made into bath and kitchen scrubbies! It makes sense, after all. Before man made sponges and scrubbies, our ancestors had to use something. They used hard gourds as food receptacles and luffas and ocean sponges for eating and scrubbing! (When they bathed that is). ?

A bath sponge you can grow!

This past Christmas was our first year to try making luffa soap, and it was fun, including some trial and error!

My mistake was to try to skip a step. Bad idea. The first batch looked good and smelled great but ended up too hard and scratchy for anything but scrubbing calloused feet. Which it’s actually great for that, so if you need a stiff foot scrubber, then skip the moisten-the-luffa step. Meanwhile, here’s our process.

We REALLY had fun growing and making soaps with this amazing vegetable, though not as excited about the food value, though you can eat luffa.

We saved seeds from our first batch and will definitely growth them again this year, which you can read about in another article linked at the bottom of this one. There you will also see pictures of our luffas growing.

The loofah sponge is great as a “scrubby” and will last through many uses. One particular enhancement is to infuse the sponge with soap. Not only practical, but a very artful and fun project to make your own custom colored, custom scented soap scrubbies.

How to Make Luffa Soap

You will need a pre-skinned dried luffa vegetable that you’ve grown or purchased. It’s a lot cheaper to grow, but it’s a climbing vine plant that can take up a lot of space, so if you want to try this first to see if you even like it enough to grow it, you can buy real luffa sponges on Amazon.

12 simple steps, and you’ll have your very own homemade luffa soap!

  1. Soak luffa in water for approximately 5 minutes
  2. Using a serrated knife, cut a 1 1/4 inch slice
  3. Place sliced luffa on a piece of parchment paper
  4. Spray with rubbing alcohol to help soap adhere to luffa
  5. Wrap the parchment paper around around to cradle the luffa
  6. Secure parchment paper around the luffa with rubber bands
  7. Please 6 oz of soap in a glass measuring cup and melt in microwave
  8. Add a drop or two of your choice of food coloring
  9. Add a few drops of essential oil or fragrance and stir
  10. Pour the soap blend into the loofah soap in the parchment “container” until the soap is covering the luffa. You will see all of the soap filling up the holes and porous areas
  11. Let is set up. This happens fairly quickly but you can speed it up by placing in fridge
  12. When set, remove from parchment paper and smooth off any loose flakes and pieces

Now get creative and use different fragrances and essential oil remedies. For example, you may want to make a peppermint version to have on hand for bathing with congestion, or a lavender version for soothing relaxation, or a citrus fragrance for morning wakefulness. Or you may prefer to focus on your favorite scents. Having grown up in Hawaii, my wife loves gardenia and plumeria fragrances, so I made one of those for her.

Natural Loofah Soap

We prefer to use all natural vegetable soap making materials for the base and the coloration.

Here’s our 2nd attempt at making luffa soap bars. Our first attempt we skipped the step of soaking the luffa, and that was a mistake as the luffa ended up way too scratchy for bathing, however it was perfect for scrubbing calloused feet!

Homemade soaps are especially beneficial for those with allergies to other soaps. For example, my wife and daughter are both allergic to soy, so I made sure to get a soy-free natural glycerine soap.

I really enjoyed making this and can see why some folks really get into soap making! If you’re interested in this kind of thing you might also enjoy this article on making lotion bars. Also, if you’re going to be making more of your own, you may want to grow your own medicinal and fragrant herbs.

Enjoy and if you make some, please share your photos via email or the GardensAll Facebook page. We love to see them!
