For convenience, most food-grade silicone molds are dishwasher-safe—place them on the top rack away from heating elements to prevent warping.

• Avoid High-Concentration Cleaners

  Do not use bleach, ammonia-based cleaners, or degreasers, as these can break down the polymer structure of silicone over time. Strong chemicals may also leave residues that could transfer to food. For stubborn stains or odors, use a paste of baking soda and water or a vinegar solution (1:1 ratio), then rinse thoroughly.

• Storage Guidelines – Prevent Deformation and Degradation

  Store molds in a cool, dry place away from direct sunlight and heat sources such as stoves or radiators. UV exposure and high ambient temperatures can accelerate aging, causing discoloration and brittleness. Avoid stacking heavy objects on top of molds to prevent permanent deformation. For long-term storage, lightly dust with cornstarch to prevent sticking, especially in humid environments.

• Oven Safety Checks – Inspect Before Use

  Before each baking cycle, inspect the mold for signs of wear such as cracks, tears, or surface pitting. Damaged molds can harbor bacteria and may release particles into food. Also, ensure the mold is placed on a flat baking sheet for stability—never place flexible silicone molds directly on oven racks without support, as they can sag or spill.

Pro Tip: To enhance release and protect your mold, lightly grease it with a food-safe oil (like coconut or canola) or use a non-stick baking spray—even though silicone is naturally non-stick, this extra step helps preserve surface integrity over time.

Additional Care Recommendations

• Replace molds showing persistent odors or discoloration, even after deep cleaning.
• Do not use sharp utensils inside molds to avoid punctures.
• Label molds used for food vs. crafts (e.g., candles, soap) to prevent cross-contamination.
• Rotate molds regularly if used frequently to ensure even wear.
