5 Common Soap Making Mistakes and How to Fix Them

Soap making is a fun and rewarding craft, but even experienced soap makers run into problems from time to time. Whether you’re new to the process or troubleshooting an unexpected issue, knowing how to fix common soap-making mistakes can save your batch. Here are five common mistakes and how to avoid them.

1. Soap Won’t Trace

Problem: Your soap mixture remains thin and refuses to thicken, even after extended blending.

Fix: Check your ingredients—using incorrect oil ratios, expired lye, or insufficient lye concentration can prevent trace. Make sure your lye is fresh, your measurements are accurate, and you’re blending thoroughly with an immersion blender rather than stirring by hand.

2. Soap is Too Soft

Problem: Your finished soap is too soft and takes too long to harden.

Fix: Soft soap is often caused by too much soft oil (like olive or castor oil) or too much liquid. Increase hard oils like coconut or palm oil, reduce water content, or add sodium lactate to help harden the bars.

3. Soap is Crumbly or Brittle – Common Soap Making Mistakes

Problem: Your soap crumbles or breaks apart when cut.

Fix: This often happens due to too much lye (a lye-heavy soap) or insufficient water. Double-check your lye calculations using a lye calculator. If the soap is already made, you can rebatch it by grating and melting it down with additional oils.

4. Soap Has White Streaks or Spots

Problem: White spots or streaks appear throughout your soap.

Fix: This is often caused by undissolved lye or improper mixing. Always ensure your lye is fully dissolved before adding it to the oils. Using a stick blender for full incorporation can help eliminate this issue.

5. Soap is Sticky or Won’t Unmold

Problem: Your soap sticks to the mold or feels tacky to the touch.

Fix: Sticky soap is often due to excessive water or an insufficient curing time. Allow more time for the soap to harden, or pop it in the freezer for a few hours to help it release from the mold.
