Ingredient Notes

Top Tips

You may also add other fragrance oils, such as bergamot, mint, lavender, and ginger, to the mix. These best complement grapefruit fragrance.
Only pick one (to avoid overpowering scents) and ensure the fragrance oil you'll use is safe for the skin.
Pouring at a medium temperature avoids premature solidification and ensures smooth and even bars.

Frequently Asked Questions

Can I add coconut oil to the recipe?

Yes, it can enhance the soap’s moisturizing properties and boost its cleaning power, helping to create a richer lather and more bubbles.

Can I use a microwave to melt the soap base?

Yes, you can, but use a moderate heat setting to melt the soap in short intervals. Heat the soap in 20 to 30-second bursts. After each interval, stir the soap base to help it melt evenly and to check the consistency.

What's better, liquid soap, cold process soap, or melt and pour dish soap?

Each type has advantages, whether you’re looking for ease of use, customization, or a particular aesthetic.
Liquid dish soap is highly convenient but often contains harsh chemicals, such as sodium lauryl sulfate, which can cause skin and eye irritation.
Cold process soap is typically designed for skincare, not dishwashing, and will lack degreasing power.
Melt-and-pour soap is the safest option because you have complete control over the ingredients and ensure that no lye is added.

Storage Tips

DIY dish soap bars can become mushy and hard to use if not stored properly. Make sure to dry your soap bar completely after using it. Keep your dish soap away from water and direct sunlight.

For easier storage, you can use a soap dish with proper ventilation and drainage. Look for ones with small holes and ridges.
