What to Do if Your Silicone Dinnerware Smells After the Dishwasher

Silicone dinnerware has become a favorite in many homes—especially for parents, minimalists, and eco-conscious consumers. It's lightweight, durable, BPA-free, and super easy to clean… or so we think—until it comes out of the dishwasher smelling a little off.

If your silicone bowls, plates, or utensils are coming out of the dishwasher with a weird odor (think musty, sour, or like last night's spaghetti), you’re not alone. Here's why it happens and, more importantly, how to fix it and keep your silicone dinnerware fresh and odor-free.

 

Why Silicone Absorbs Odors

Silicone is non-porous, but it’s also a bit like a sponge when it comes to lingering smells—especially when exposed to high heat, strong foods (like garlic or tomato sauce), or certain dishwasher cycles. Over time, oils and food particles can cling to the surface, and the heat from the dishwasher can actually bake those smells in, rather than remove them.

 

What To Do When Your Silicone Dinnerware Smells

Here’s a step-by-step guide to deodorizing your silicone dinnerware:

1. Give It a Deep Clean (By Hand)

Start by washing your silicone pieces thoroughly with warm, soapy water and a non-abrasive sponge. Make sure to get into any creases or textured surfaces. Dishwashers often don’t scrub as well as we think, and leftover oils can trap odors.

2. Try a Baking Soda Paste

Mix baking soda with a little water to create a thick paste. Apply it generously to the silicone and let it sit for at least 30 minutes (overnight is even better). Rinse thoroughly. Baking soda is a natural deodorizer and helps draw out embedded smells.

3. Soak in White Vinegar

Fill a basin with a mixture of one part white vinegar and one part hot water. Soak your silicone items for 1–2 hours. Rinse well. Vinegar neutralizes odors and helps break down residual grease.

4. Bake It (Yes, Really)

If smells still linger, try placing your silicone dinnerware in the oven. Set the temperature to 250°F (120°C) and let the items bake for about 20 minutes. This can help “off-gas” the odors. Let them cool completely before washing and using again. (Always double-check the manufacturer’s max temp just to be safe.)

 

Preventing Odors in the Future

Once your silicone is fresh again, here are a few tips to keep it that way:

• Avoid high-heat dishwasher cycles — stick to the top rack and skip the drying cycle if it gets too hot.
• Rinse right away after meals, especially if the food was oily or spicy.
• Hand wash regularly to keep oils from building up.
• Dry thoroughly before storing—trapped moisture can contribute to musty smells.

 

Final Thoughts

Silicone dinnerware is built to last—but like anything we use every day, it needs a little TLC. If your dishes have picked up a stubborn smell, don’t toss them! With a few household ingredients and some simple tricks, you can refresh your silicone and get it smelling as clean as it looks.
