How to Eliminate Fragrance Oil Residue from Silicone Molds

Silicone molds are a versatile tool in the world of crafting and DIY projects. They offer an easy way to create beautifully shaped candles, soaps, and other homemade items. However, one common challenge that crafters often face is dealing with the lingering scent of fragrance oil in their silicone molds. If you’ve encountered this issue and are wondering how to get rid of fragrance oil residue effectively, you’re in the right place. In this article, we will provide you with a comprehensive guide to banishing those stubborn scents and ensuring your silicone molds are ready for your next creative venture.

Understanding the Problem

Before we dive into the solutions, let’s take a moment to understand why fragrance oil scents tend to cling to silicone molds. Silicone is a porous material, which means it can absorb and trap odors over time. When you use fragrance oils in your molds, the oils can seep into the silicone’s tiny pores, leaving behind a persistent aroma that can interfere with your next project.

Materials You’ll Need

To effectively remove fragrance oil residue from your silicone molds, gather the following materials:

1. Dish Soap

2. Baking Soda

3. White Vinegar

4. Warm Water

5. Soft Bristle Brush

6. Plastic Wrap

7. Coffee Grounds

8. Freezer

Step-by-Step Cleaning Process

Now that you have your materials ready, let’s walk through the process of eliminating fragrance oil residue from your silicone molds:

Step 1: Preparing a Soapy Solution

Begin by filling a bowl or basin with warm water and adding a few drops of dish soap. Mix it until it forms a soapy solution.

Step 2: Soaking the Silicone Mold

Place the scented silicone mold into the soapy water. Ensure it is fully submerged, and let it soak for at least one hour. This will help loosen the fragrance oil residue.

Step 3: Scrubbing

After soaking, use a soft bristle brush to gently scrub the silicone mold. Pay close attention to any areas where residue is particularly stubborn. This should help dislodge the trapped oils.

Step 4: Rinsing

Rinse the silicone mold thoroughly with warm water to remove any soap and residue. Be sure to rinse both the interior and exterior of the mold.

Step 5: Vinegar Solution

In a separate container, create a mixture of equal parts white vinegar and warm water. Soak the silicone mold in this solution for another hour. Vinegar is excellent for neutralizing odors.

Step 6: Final Rinse

Give the silicone mold one final rinse with warm water to remove any vinegar smell.

Step 7: Coffee Grounds

To further eliminate any lingering odors, fill the silicone mold with coffee grounds. Coffee grounds are known for their ability to absorb and neutralize smells.

Step 8: Freezing

Cover the silicone mold filled with coffee grounds with plastic wrap and place it in the freezer for 24 hours. The cold temperature will help seal in the fresh, clean scent.


By following these simple steps, you can effectively remove fragrance oil residue from your silicone molds, ensuring they are scent-free and ready for your next creative project. Say goodbye to unwanted odors and hello to a fresh start for your crafting endeavors.
