Cleaning silicone feeding gear, including bowls, bento boxes and placemats, is simpler than most parents expect. The best approach to cleaning a silicone air fryer liner or baby bowl is the same: rinse off food straight after the meal, wash with warm soapy water or place pieces on the top rack of the dishwasher, and air dry. That covers everyday use. But tomato stains, lingering smells and gear left sitting too long need a little more attention. Here is what actually works.

Your Daily Cleaning Routine for Silicone Feeding Gear
Speed matters here. The longer food sits on silicone, the harder it becomes to remove. A quick rinse under the tap right after a meal does most of the work before you even reach for the dish soap.
For daily cleaning:
- Rinse with warm water immediately after the meal.
- Wash with a small amount of dish soap and a soft cloth or sponge. Avoid abrasive scrubbers, which can scratch the surface over time.
- Place on the top rack of the dishwasher if you prefer. Silicone is dishwasher safe and handles the heat well.
- Air dry fully before stacking or storing. Trapped moisture can cause musty smells.
That routine covers most days. Bento boxes with multiple compartments take an extra thirty seconds to rinse properly, especially around the edges and lid seal. If your little one is eating a variety of snacks and finger foods, rinsing compartments separately makes sure nothing gets missed.
How to Deep Clean Silicone Bowls and Bento Boxes
A weekly deep clean keeps silicone in good condition and prevents build-up that daily washing misses.
Two methods work well:
- Boiling: Submerge the silicone pieces in a pot of boiling water for three to five minutes. This sanitises without chemicals and loosens stubborn residue.
- Oven method: Place clean silicone items in an oven at 180 degrees Celsius for around ten minutes. This burns off odours and any remaining grease.
Both methods are safe for food-grade silicone. Always check that your gear is labelled food-grade before using heat beyond a dishwasher cycle.
If you are unsure whether your bento box is the right fit for your child's age and appetite, the bib, bowl and bento sizing guide is a practical starting point before you replace anything.
Removing Stains and Odours from Silicone
Tackling Tomato and Curry Stains
Silicone is porous enough to absorb pigment from strongly coloured foods. Tomato-based sauces, curries and pureed carrot are the most common culprits.
- Make a paste with bicarbonate of soda and a small amount of dish soap. Rub it onto the stained area, leave for fifteen minutes, then scrub gently and rinse.
- For stubborn stains, soak the piece in a diluted white vinegar solution (one part vinegar to three parts water) for thirty minutes before washing.
- Sunlight also works. Leave clean, stained silicone outside in direct sun for a few hours. UV exposure fades food stains naturally.
Getting Rid of Lingering Smells
A silicone bowl that smells like last Tuesday's fish pasta is not damaged, just needs a reset.
- Soak in a bicarbonate of soda and warm water solution overnight.
- Use the oven method above. Heat breaks down the odour-causing compounds trapped in the silicone.
- Make sure the piece is completely dry before storing. Smell is almost always worse when moisture is trapped.
Can Silicone Go in the Washing Machine?
No. A washing machine is not suitable for silicone feeding gear. The agitation cycle can damage seals and warp edges, especially on bento box lids. Stick to the dishwasher, hand washing or the boiling method.
Silicone placemats with suction bases are best hand washed. The suction cups can lose their grip over time if put through a dishwasher repeatedly.
Habits That Make Silicone Last Longer
- Rinse immediately after every meal. Do not leave food sitting.
- Avoid sharp utensils directly on silicone surfaces.
- Store pieces flat or loosely stacked. Folding or compressing silicone repeatedly weakens the shape.
- Check lids and seals regularly. A warped lid will not keep food fresh or contained in a bag.
Well-maintained silicone feeding gear can last for years. If you are choosing new pieces, it is worth reading through what to look for in a kids bento box before buying, so you get something durable from the start.
