Why
The product is made of 100% platinum silicone, a thermoset elastomer that withstands temperatures up to 446°F (230°C) without melting or warping. Dishwasher heat (typically 120-160°F) and alkaline detergents do not degrade silicone; the material is inert and non-porous, so it resists staining and odor absorption. The specific failure mode for low-quality silicone is warping or becoming brittle over time, but platinum-grade silicone remains flexible and durable. Most manufacturers, including OXO and Silikomart, explicitly state their silicone ice trays are top-rack dishwasher safe. There are no separate parts (lid, gasket, etc.) — the tray is a single piece. However, avoid contact with the heating element to prevent localized overheating.
How do you wash Silicone Ice Tray?
- Remove any ice cubes and rinse the tray with cool water to loosen residue.
- Place the tray on the top rack of the dishwasher, ensuring it is not touching the heating element.
- Use a mild detergent; avoid bleach or abrasive additives.
- Run a normal or light cycle with heated dry turned off to minimize heat exposure.
- After the cycle, remove the tray and inspect for any trapped water in the cavities.
- Hand dry with a soft cloth or air dry completely before storing.
- For stubborn stains, soak in a 1:1 vinegar-water solution for 15 minutes before washing.
What happens if you put Silicone Ice Tray in the dishwasher?
If you put a 100% platinum silicone ice tray in the dishwasher, nothing harmful will happen after one wash — it will come out clean and intact. After repeated washes (50+ cycles), you may notice a slight haze or mineral deposit on the surface if you use hard water, but this is cosmetic and can be removed with vinegar. The material will not warp, crack, or degrade because silicone is chemically stable. However, if the tray is made of lower-quality silicone (e.g., filled with plasticizers), it may become sticky, brittle, or develop a white residue over time. The damage is cosmetic only; the tray remains functional. To avoid any risk, always place it on the top rack away from the heating element.
Frequently asked questions
- Can silicone ice trays go in the microwave?
- Yes, 100% platinum silicone is microwave-safe up to 446°F (230°C). However, never microwave an empty tray; always have water or food inside to avoid overheating.
- Can silicone ice trays go in the freezer?
- Yes, silicone remains flexible at sub-zero temperatures (down to -40°F/-40°C). The tray will not crack or become brittle.
- How do I remove odors from a silicone ice tray?
- Soak the tray in a mixture of equal parts white vinegar and warm water for 30 minutes, then rinse thoroughly. Baking soda paste also works.
- How often should I replace a silicone ice tray?
- High-quality platinum silicone trays can last for years. Replace if you notice stickiness, brittleness, or a persistent odor that doesn't wash out.
