how to get smells out of silicone

3 min read 05-02-2025

Silicone is a fantastic material for many kitchen and household items – durable, heat-resistant, and non-stick. But its porous nature can sometimes lead to lingering odors. This comprehensive guide will show you how to effectively remove smells from your silicone items, from baking molds to baby bottles.

Why Do Silicone Items Absorb Smells?

Silicone's slightly porous nature means that odor-causing molecules can become trapped within its material. This is especially true after using it with strong-smelling foods like garlic, onions, fish, or strongly spiced dishes. The longer the smell is present, the more deeply it can embed itself.

How to Remove Smells from Silicone: A Step-by-Step Approach

The best method depends on the type of silicone and the intensity of the odor. Here's a tiered approach, starting with the simplest techniques and progressing to more intensive methods:

1. Simple Washing and Rinsing

For Mild Odors: Sometimes, a thorough washing with hot, soapy water is all you need. Use a dish soap designed to cut grease, and scrub gently with a non-abrasive sponge or brush. Rinse well with hot water and allow to air dry completely. This removes surface odors effectively.

2. Baking Soda Power

For Moderate Odors: Baking soda is a natural odor absorber. Make a paste of baking soda and water, and apply it to the affected silicone item. Let it sit for at least 30 minutes (or even overnight for stubborn smells). Then, scrub gently and rinse thoroughly. This method neutralizes many common odors.

3. White Vinegar Solution

For Moderate to Strong Odors: White vinegar is another effective natural deodorizer. Soak the silicone item in a solution of equal parts white vinegar and water for several hours, or even overnight. Then, scrub and rinse well. This tackles odors through its acidity. Remember to rinse thoroughly, as the vinegar scent can linger if not properly removed.

4. Dishwashing Detergent Soak

For Strong Odors: A soak in hot, soapy water with a powerful dishwashing detergent can help remove persistent odors. Let the item soak for at least 30 minutes, or even longer depending on the severity of the smell. Follow with thorough rinsing and air drying.

5. Boiling Water Method

For Strong Odors (Safe for Heat-Resistant Silicone): If your silicone item is heat-resistant (check the manufacturer's instructions!), boiling it in water for a few minutes can help release trapped odors. Ensure the item is completely submerged and boil for no more than 5 minutes. Remove carefully and allow to cool before rinsing.

6. Bleach Solution (Use with Caution!)

For Extremely Stubborn Odors (Use Sparingly): Bleach is a powerful disinfectant and odor remover, but it should be used sparingly and only as a last resort, as it can damage some silicone. Always dilute bleach heavily—a ratio of 1 part bleach to 10 parts water is a safe starting point. Soak the item for a short time, then rinse EXTREMELY well. Never leave silicone submerged in bleach for extended periods.

7. Activated Charcoal

For Persistent Odors: Activated charcoal is a highly porous material that effectively absorbs odors. Place the silicone item in a sealed container with activated charcoal for several days. The charcoal will draw the odors out of the silicone. This is a great option for items with intricate designs that are hard to clean thoroughly.

Preventing Odors in Silicone Items

Clean Immediately After Use: The quicker you clean your silicone items after use, the less likely odors are to set in.
Proper Storage: Store silicone items in a clean, dry place, away from strong-smelling substances.
Avoid Overcrowding: When using silicone baking molds, avoid overcrowding them, as this can trap odors and moisture.

Specific Silicone Items and Odor Removal

Silicone Baking Molds: Often benefit from the baking soda paste or boiling water method.
Silicone Baby Bottles: Stick to milder methods like soapy water and baking soda to avoid harsh chemicals.
Silicone Utensils: Usually respond well to simple washing and rinsing or a quick soak in vinegar water.

By following these steps, you can effectively remove smells from your silicone items and keep them fresh and odor-free. Remember to always check the manufacturer's instructions before using any cleaning method, especially those involving heat or bleach.
