Luffa soap is one of the easiest exfoliating soaps you can make at home. The natural luffa sponge gently exfoliates your skin while the melt and pour soap cleans and moisturizes.

In this tutorial, I’ll show you how to make a simple luffa soap on a rope using melt and pour soap. The rope makes it easy to hang in the shower so the soap can dry between uses.

Why Make Luffa Soap?

Luffa soap combines two things in one bar:

• Natural exfoliation from the luffa sponge
• Gentle cleansing from the soap

The rope allows the soap to hang and dry between uses, which can help extend the life of the soap.

Step 1 – Cut and Weigh the Soap

Start by cutting your melt and pour soap base into small chunks and weighing out 100 grams.

Cutting the soap into smaller pieces helps it melt more evenly.

---

Step 2 – Prepare the Luffa and Rope

Cut a piece of twine long enough to create a loop for hanging.

Tie the twine securely around the luffa sponge.

Place the luffa inside your silicone mold, leaving the string hanging outside of the mold so it becomes embedded in the soap.

Step 3 – Melt the Soap

Place the soap cubes into a microwave safe container.

Microwave in 10 second intervals, stirring between each interval until the soap is completely melted.

Melting slowly helps prevent overheating the soap base.

Step 4 – Add Fragrance and Color

Once the soap is fully melted:

Add:

• 6 grams fragrance oil
• Mica powder

Stir gently until everything is fully mixed.

Tip

If the mica powder doesn’t want to mix in completely, spray a small amount of rubbing alcohol onto the surface of the soap to reduce surface tension.

---

Step 5 – Pour the Soap

Slowly pour the melted soap into the mold, covering the luffa sponge.

Once poured, spray the top of the soap with rubbing alcohol.

This helps pop any air bubbles that may form.

What to Do If You Run Out of Soap

When I first made this soap, I only used 50 grams of melt and pour soap.

It turned out that I didn’t have enough soap to fully cover the luffa.

To fix it, I simply:

1. Melted an additional 50 grams of soap
2. Sprayed the first layer with rubbing alcohol
3. Poured the additional soap on top

Spraying with alcohol helps the two layers stick together properly.

---

Allow the Soap to Cool

Allow the soap to fully cool and harden before removing it from the mold.

Once unmolded, your luffa soap on a rope is ready to use.

---

Prevent Soap Sweating

Melt and pour soap can sometimes develop small droplets on the surface called glycerin dew.

You can learn more about that here Soap Sweating or Glycerin Dew
To prevent this, wrap finished soap in plastic wrap if you are storing it.
