The Best Way to Clean Silicone Kitchen Utensils

By

 Silicone spatulas, baking mats, and cooking spoons are essential in modern kitchens—they are durable, heat-resistant, and won't scratch your cookware. However, over time, these utensils can develop a sticky grease film, white cloudy spots, or lingering food odors that regular dish soap just can't seem to shake.

If your silicone utensils still feel slippery after washing or carry the sharp scent of garlic, onion, or spices, you aren't imagining it. Silicone has a surface structure that naturally attracts and retains cooking oils.

This guide covers simple, food-safe methods using everyday household items to restore your silicone kitchen tools so they feel and smell brand new.

Quick Reference

  • Daily Method: Hot water + grease-cutting dish soap

  • For Sticky Grease & Odors: Soak in warm water with baking soda (30–60 mins)

  • For Deep Odor Removal: Use gentle heat only if the silicone manufacturer's instructions allow oven use.

  • Total Time: 15 to 60 minutes (Difficulty: Easy)

Clean silicone kitchen utensils on a modern kitchen countertop.

Always start with a thorough basic wash. Using comfortably hot water can help loosen grease and make silicone utensils easier to clean.

  1. Fill your sink or a large bowl with very hot water.

  2. Add a few drops of grease-cutting dish soap and mix until bubbly.

  3. Submerge the silicone items and let them soak for 10–15 minutes.

  4. Scrub gently using a soft sponge.

  5. Rinse thoroughly under warm running water and allow to air dry completely.

Tip: Avoid using steel wool or abrasive scouring pads. They create micro-scratches on the silicone, making it even easier for oils to get trapped in the future.

Method 2: Baking Soda Soak (For Sticky Residue)

When standard dish soap leaves behind a tacky or slippery feel, baking soda is your best solution. Its mild abrasive and deodorizing properties can help loosen residue and reduce lingering odors.

  • Ingredients: 2 tablespoons baking soda + 4 cups (1 liter) hot water

  1. Dissolve the baking soda completely in hot water.

  2. Fully submerge your silicone utensils and let them soak for 30 to 60 minutes.

  3. Wipe them down with a non-abrasive sponge.

  4. Rinse thoroughly and let dry completely.

Method 3: Heat Treatment (For Strong Garlic & Spice Odors)

If your spatulas still smell like onions or curry after soaking, heat works wonders. Gentle heat may help loosen some persistent odors, but silicone products have different heat limits, so always check the manufacturer's instructions before using an oven.

  1. Check the manufacturer's instructions to confirm that the silicone item is oven-safe.

  2. If oven use is allowed, use a temperature within the manufacturer's recommended range.

  3. Place the clean silicone tools on a baking sheet and heat them according to the product instructions.

  4. Allow the utensils to cool completely, then wash them with warm water and dish soap.

Method 4: White Vinegar Soak (For Mineral Deposits)

If you notice a cloudy white film on your utensils, it is usually caused by hard water minerals rather than grease.

  • Ratio: 1 part white vinegar to 2 parts warm water

  • Steps: Soak the utensils for 15 minutes, then rinse thoroughly.

Note: Avoid combining vinegar and baking soda in the same soaking step. Mixing an acid and a base neutralizes both, reducing their overall cleaning power.

How to Fade Tomato & Turmeric Stains

Discoloration from tomato sauce, turmeric, or berries doesn't mean your utensil is dirty or unsafe. To lift deep pigments:

  1. Make a thick paste using baking soda and a few drops of water.

  2. Rub the paste onto the stained area and let it sit for a few minutes.

  3. Wash off the paste, then place the utensil in direct sunlight for a few hours.

Sunlight may help fade some food stains over time, although the results can vary depending on the type and age of the stain.

Common Mistakes to Avoid

  • Storing tools while damp: Moisture trapped in drawers can cause mildew or stale smells.

  • Using sharp blades: Never use knives directly on silicone surfaces, as cuts cannot be repaired.

  • Letting grease sit for days: The longer oil remains on silicone, the deeper it settles into the surface texture.


Frequently Asked Questions

Are silicone utensils dishwasher safe?

Many silicone utensils are dishwasher safe, but you should check the manufacturer's care instructions first. For stubborn grease buildup, soaking the item in warm water with dish soap or baking soda can provide additional cleaning.

Can baking soda scratch silicone?

Baking soda is generally gentle enough for silicone utensils when used with a soft sponge and light pressure. Avoid aggressive scrubbing, especially on damaged or textured silicone surfaces.

Is bleach safe for silicone tools?

It is generally better to avoid bleach unless the manufacturer's instructions specifically recommend it. For routine cleaning, dish soap, warm water, and baking soda are usually sufficient for removing grease and odors.

Taking a few minutes every few weeks to deep-clean your silicone utensils can help keep them clean, fresh-smelling, and in good condition for longer.
