Soft silicone ice cube trays have become increasingly popular due to their flexibility, durability, and easy release. However, maintaining their cleanliness and longevity requires proper care and cleaning techniques. Here are comprehensive tips to help you keep your soft silicone ice cube trays in pristine condition:

Pre-Use Preparation

Before using your soft silicone ice cube trays for the first time, it is essential to prepare them properly to eliminate any potential impurities or manufacturing residue.

– Wash with Soap and Water: Thoroughly wash the trays with warm water and a mild dish soap. Use a soft sponge or cloth to avoid scratching the silicone surface.

– Rinse Thoroughly: Rinse the trays repeatedly with clean water to remove any soap residue. Allow them to air dry completely before filling them with water.

Regular Cleaning

Regular cleaning is crucial to prevent bacteria and mold growth while maintaining the hygiene of your ice cubes.

– Wash Weekly: After each use, wash the trays promptly with warm and soapy water. Avoid using abrasive materials that can damage the silicone.

– Rinse Well: Rinse the trays thoroughly to remove all soap residue. Allow them to air dry completely before storing or reusing.

– Disinfect Occasionally: To eliminate any lingering bacteria, disinfect the trays with a diluted bleach solution (1 tablespoon bleach per quart of water). Soak the trays for about 15 minutes and then rinse thoroughly.

Stain Removal

Over time, food particles or beverages may leave stains on your silicone ice cube trays. Here’s how to effectively remove them:

– Baking Soda Paste: Create a paste by mixing baking soda with a small amount of water. Apply the paste to the stained areas and let it sit for a few hours. Scrub the paste away with a soft sponge and rinse the trays thoroughly.

– Vinegar Solution: Fill the ice cube trays with an equal mixture of vinegar and water. Let it soak for several hours or overnight. Rinse the trays thoroughly and air dry.

– Hydrogen Peroxide: If other methods fail, try using hydrogen peroxide. Pour hydrogen peroxide into the stained area and let it sit for a few hours. Rinse the tray thoroughly and allow it to air dry completely.

Odor Elimination

Ice cube trays may occasionally develop odors due to bacteria or food residue. Here are some effective odor-eliminating techniques:

– Baking Soda: Sprinkle baking soda into the ice cube trays and let it sit overnight. Baking soda absorbs odors, leaving the trays fresh and clean.

– White Vinegar: Fill the ice cube trays with white vinegar and let it soak for several hours. Vinegar neutralizes odors and disinfects the trays.

– Lemon Juice: Squeeze fresh lemon juice into the ice cube trays and let it sit for 30 minutes. Lemon juice has antibacterial and deodorizing properties.


Proper storage is essential to maintain the cleanliness and longevity of your silicone ice cube trays.

– Dry Thoroughly: Always ensure that the trays are completely dry before storing them. Moisture can promote mold and bacteria growth.

– Store Upright: Store the trays upright to prevent water accumulation and ensure proper ventilation.

– Avoid Direct Sunlight: Keep the trays away from direct sunlight, as it can degrade the silicone material over time.
