How to Make Soap Filled Loofa Sponges

Updated February 21, 2017

A loofah is a vegetable that grows on a vine and resembles a large cucumber. When it has dried out, a loofah makes an excellent sponge. The resulting sponge can be used for gently skin exfoliation or to clean household surfaces. Loofah sponge soaps make an excellent addition to your skin care regimen and do not take a huge amount of time or money to make. Start with home-grown and dried loofah sponges, or buy them from the candle and soap aisle of any craft store.

Use the electric knife to slice an inch off each end of the loofah, exposing the inner chambers. Discard the ends or use them for another project.

Stand the loofah on one cut end, with the other cut end facing up. Cover the cut end that is facing up with a piece of cling film and secure with a rubber band.

Turn the loofah over and place it on a flat surface with the cling film side down.

Use the knife to chop the melt and pour soap into rough 1-inch chunks. Place the chunks of soap into the glass bowl and microwave for two minutes.

Stir the soap with the wooden spoon. If the soap is not all melted, microwave it for 20 seconds, then check it again. When the soap has all melted, add 6 drops of essential oil if desired. Stir with the wooden spoon.

Carefully pour the hot liquid soap into the loofah. Fill one channel of the loofah at a time. Most loofah sponges have three open channels that can accept soap, but some can have four or more.

Let the soap cool entirely. You should not feel any heat when you touch the top or side of the loofah.

Lay the loofah on its side and remove the cling film.

Cut the loofah into 1-inch slices using the electric knife. Let the slices cure overnight before using or packaging. Most loofahs will yield between five and seven finished soaps.


If the soap didn't make it all the way through to the very end of the loofah, turn the loofah over and fill in the missing parts with melted soap. Let cool completely before cutting. If you don't have an electric knife, you can use a serrated edge bread knife to slice the loofah. If you grow your own loofah sponges, you'll need to hang them to dry for about a month before you can use them for soap.


Don't spill the soap; it is hot enough to burn your skin. Make sure the soap is completely melted before pouring. Large lumps won't fill in the areas of the loofah.
