10 Powerful Tips on How to Clean Silicone Bakeware Without Ruining It

How to Clean Silicone Bakeware in the Dishwasher (And Why It Often Doesn’t Work)

If you’re tossing your silicone bakeware into the dishwasher and wondering why it still feels greasy or smells weird afterward, you’re not alone. Many people assume that because silicone is labeled “dishwasher-safe,” it doesn’t need special attention. But when it comes to how to clean silicone bakeware, the dishwasher isn’t always enough.

The biggest issue is grease. Silicone tends to hold on to oil more than metal or glass, and standard dishwasher cycles often can’t fully break down that buildup, especially if you’re using cooler water or eco modes. That oily film you feel afterward? It’s not your imagination. It’s leftover fat that has clung to the surface and survived the rinse cycle.

Another factor: food particles and sugar. If you’ve baked something sticky, like brownies or cinnamon buns, small bits of residue can get trapped in the corners of silicone molds or trays. The dishwasher’s spray arms might not reach those tight areas effectively, especially if the bakeware is bent or folded inside the rack.

Plus, dishwashers don’t always dry silicone well. Trapped moisture can cause a musty smell or contribute to that slightly tacky texture you feel after cleaning. Left unchecked, this buildup can make your bakeware less nonstick over time.

So while silicone is technically dishwasher safe, the best approach to clean silicone bakeware includes a few extra steps, like pre-rinsing, degreasing, and the occasional deep clean. We’ll get into that next.

How to Clean Silicone Bakeware Safely: Step-by-Step Guide

Knowing how to clean silicone bakeware the right way makes all the difference in keeping it nonstick, odor-free, and long-lasting. Whether it’s your first clean or a routine scrub, follow this safe and effective cleaning process:

1. Let It Cool Completely First

Never clean hot silicone bakeware straight from the oven. Let it cool naturally to avoid warping and to make the cleaning process easier. Plunging hot silicone into cold water can cause stress on the material.

2. Rinse Off Any Loose Debris

Rinse your bakeware under warm running water to remove crumbs or food particles. This prevents sticky bits from drying onto the surface during cleaning.

3. Wash With Warm Water and Mild Dish Soap

Use a non-abrasive sponge or soft cloth with warm, soapy water. Dish soap that cuts grease — like Dawn or Seventh Generation — works well to lift oil. Avoid using scouring pads or steel wool, which can damage the silicone’s surface over time.

4. Focus on Greasy or Sticky Areas

If the bakeware still feels slick, make a paste of baking soda and water and gently scrub the surface. This helps break down baked-on grease without harsh chemicals.

5. Rinse Thoroughly and Let It Dry Completely

After scrubbing, rinse with clean water to remove all soap or baking soda residue. Then, air-dry the bakeware or use a soft towel. Make sure it’s completely dry before storing to prevent mold or odor buildup.

This method works for both hand-washing and as a follow-up after a dishwasher cycle that didn’t do the job. Taking a few extra minutes to clean silicone properly extends its life and keeps it performing like new.

How to Clean Silicone Bakeware When It Still Feels Greasy or Smells Bad

Sometimes, even after a regular wash, silicone bakeware still feels slick or smells like garlic, butter, or last week’s banana bread. In that case, it’s time for a deep clean — and yes, it’s totally doable without damaging your bakeware.

Here’s how to clean silicone bakeware that’s developed stubborn grease or odors:

1. Try a Baking Soda Scrub

Sprinkle baking soda directly onto the silicone surface. Add just enough water to form a paste, then gently scrub using a soft sponge or cloth. Let it sit for 15–20 minutes before rinsing thoroughly. This breaks down grease and helps remove lingering smells.

2. Soak in White Vinegar or Lemon Water

For strong odors, fill your sink or a large bowl with hot water and add a splash of white vinegar or fresh lemon juice. Soak the silicone for 30 minutes to an hour. Vinegar neutralizes odor while lemon adds a fresh scent. Rinse well afterward.

3. Use the Oven Method (With Caution)

To remove stubborn oil buildup, place your silicone bakeware on a baking sheet and “bake” it in a cool oven (around 350°F / 175°C) for 10 minutes. This process helps burn off leftover oils. Be sure to monitor it closely — never leave it unattended, and don’t use this method too frequently.

4. Run Through Dishwasher After Deep Clean

After soaking or baking, run the bakeware through a full dishwasher cycle for one final rinse. This removes any loosened residue or lingering odors.

These methods are safe, non-toxic, and effective for revitalizing old or greasy silicone. Just avoid using bleach, heavy-duty oven cleaners, or harsh scrubbers — they can degrade the material over time.

How to Keep Silicone Bakeware Clean and Odor-Free Long-Term

Now that you know how to clean silicone bakeware properly, the next step is keeping it that way. A few smart habits can prevent grease build-up, weird smells, and stubborn stains, saving you time and effort later.

1. Use Cooking Spray Sparingly (or Not at All)

One of the biggest culprits behind greasy silicone is excess oil spray. While it may seem helpful, most silicone bakeware doesn’t need greasing unless the recipe is exceptionally sticky. Overusing spray causes a buildup that gets baked in over time. If you do need to grease, use a light touch and wipe off the excess.

2. Rinse Immediately After Use

If you can’t wash your bakeware right away, at least give it a quick rinse. This prevents batter, oils, and sauces from drying onto the surface and becoming harder to clean later. It’s a small step that makes a big difference.

3. Store It Properly

Avoid tossing silicone bakeware into crowded drawers or folding it up tightly. Instead, store it flat or loosely rolled, especially mats or thin molds. This helps preserve the shape and prevents bending that can trap grease in creases.

4. Keep It Dry Before Storing

Silicone holds onto moisture, and if you put it away damp, it can develop a musty smell. Make sure your bakeware is 100% dry after washing, either by towel-drying or air drying on a rack.

5. Avoid Strong-Flavored or Dark Foods When Possible

Silicone can absorb odors and pigments, especially from garlic, onions, turmeric, or tomato-based sauces. If you’re using your silicone tray for savory or heavily spiced foods, give it a baking soda soak now and then to neutralize the effects.

With these habits, you’ll spend a lot less time wondering how to clean silicone bakeware — and more time actually enjoying the baking part.
