Silicone bakeware develops a persistent greasy film with repeated use that standard washing doesn't fully remove. The same properties that make silicone non-stick also cause it to repel dish soap and retain oils. A targeted approach clears it completely.
Removing the Grease Film
- Sprinkle baking soda generously over the entire interior surface of the silicone item
- Add a few drops of dish soap and work it into a paste with your fingers or a cloth
- Let sit for 10–15 minutes
- Scrub with a damp cloth or non-scratch pad
- Rinse thoroughly in hot water
- Rub your fingers across the surface — if it still feels slippery or waxy, repeat
Dishwasher
Most silicone bakeware is dishwasher safe — place on the top rack and run a hot cycle. This handles light grease well, but the persistent waxy film often requires the baking soda method regardless.
Removing Odours
Silicone absorbs cooking odours (garlic, fish, spices) over time:
- Soak in a solution of 1 part white vinegar to 3 parts water for 30 minutes
- Rinse well
- Place in a 175°C oven for 10–15 minutes — the heat drives off absorbed odour compounds
- Allow to cool completely
Removing Stains
Silicone stains from strongly coloured foods (tomato, turmeric, berries) over time. Sunlight naturally bleaches silicone — rinse the item and leave in direct sun for a few hours. This fades most staining without chemicals.
Tips
- Avoid cutting or piercing silicone with sharp utensils — small cuts harbour bacteria that can't be cleaned
- Store silicone flat or loosely rolled — sharp folds crease the material over time
- Replace silicone bakeware if it tears, has persistent odour after cleaning, or shows significant discolouration that won't fade
