Cleaning silicone baby products is refreshingly simple: wash them in warm, soapy water or run them through the dishwasher (top rack is safest for small pieces), and sterilize occasionally with boiling water or a steam sterilizer since silicone handles high heat well. The main things to avoid are abrasive scrubbers, harsh solvent based cleaners, and letting oily residue build up over time.
That said, silicone has a few quirks, like the white cloudy film that can appear after dishwasher cycles and its tendency to hold on to smells like garlic or tomato sauce. Here is a complete routine, from everyday washing to deep cleaning, so your baby's feeding gear stays fresh through months of daily use.
Why silicone is easy to keep clean
Food grade silicone is nonporous, which means bacteria, mold, and stains have a much harder time settling in than they do with scratched plastic. It also tolerates temperatures well beyond what a dishwasher or pot of boiling water produces, so you can clean it aggressively without damaging it. A well cared for silicone plate, cup, or bib can genuinely last from one child to the next.
Daily cleaning: the basic routine
For everyday washing after meals:
- Rinse promptly. A quick rinse right after the meal prevents food from drying on and keeps strong smelling sauces from lingering.
- Wash with warm water and dish soap. Use a soft sponge or dish brush. Avoid steel wool and abrasive scrub pads, which can scratch the surface and make it look dull.
- Or use the dishwasher. Most silicone feeding products are dishwasher safe. Place small items like the First Cup 2oz on the top rack or in a basket so they do not flip and collect water.
- Dry completely before storing. Air dry on a rack, ideally with cups and bowls upside down. Storing silicone damp in a closed drawer is the most common cause of musty smells.
How to sterilize silicone baby gear
Sterilizing is most important for bottle parts and anything a young baby mouths frequently. Silicone gives you several easy options:
Boiling
Submerge items in boiling water for 3 to 5 minutes, then remove with tongs and air dry on a clean surface. This works well for bottle nipples, teethers, and small cups. Items like the GentleBottle are designed to handle boiling without warping.
Steam sterilizers
Countertop steam sterilizers and microwave sterilizer bags both work with silicone. Follow the sterilizer manufacturer's instructions for load placement and timing.
How often to sterilize
Many families sterilize bottle parts daily in the early months and taper off as baby gets older, while plates and cups usually just need regular washing. Guidance varies with your baby's age and health, so check with your pediatrician about the right sterilizing routine for your situation.
Deep cleaning: film, odors, and stains
White cloudy film
That chalky white residue that shows up after dishwasher cycles is usually mineral deposits from hard water, not damage. To remove it, soak the item in a mixture of equal parts white vinegar and warm water for 30 minutes, then wash normally. Wiping silicone dry after washing helps prevent the film from returning.
Lingering smells
Silicone can absorb odors from strongly flavored foods. Two reliable fixes:
- Baking soda paste. Mix baking soda with a little water, coat the item, let it sit for a few hours, then wash and rinse well.
- Oven refresh for solid silicone. For plain silicone items with no attached plastic, valves, or straws, bake on a clean sheet at 250 degrees Fahrenheit for about an hour. Heat releases trapped odor molecules. Skip this method for anything with mixed materials.
Sticky or greasy feel
A tacky surface usually means oil residue from foods or from low quality dish soaps has built up. Soak in very hot water with a grease cutting dish soap, scrub with a soft brush, and rinse thoroughly. If an item stays sticky after proper deep cleaning, or the silicone is tearing, it is time to replace it.
Special cases: straws, valves, and textured pieces
Straw cups need extra attention because milk and smoothie residue hides inside the straw. Use a thin straw brush after each use with milk or thick liquids, and disassemble every part that comes apart, including removable valves. The straw on the Training Cup with Straw 5oz removes fully so you can brush it end to end and confirm it is clear. For open cups like the Silicone Training Cup, there are no hidden parts at all, which is one of the quiet perks of open cup drinking.
What to avoid
- Abrasive scrubbers and scouring powders that scratch the surface
- Bleach soaks and solvent cleaners, which are unnecessary for silicone and can leave residue
- Cutting directly on silicone plates with sharp knives
- Storing items wet or stacked tightly before they are dry
FAQ
Can silicone baby products go in the dishwasher?
Yes, food grade silicone is generally dishwasher safe. Place lightweight items on the top rack or in a utensil basket so they stay put, and check the care instructions for any product that combines silicone with other materials. Hand drying afterward helps prevent hard water film.
Why does my silicone plate still feel oily after washing?
Silicone attracts oils, and standard wash cycles sometimes leave a thin greasy layer behind. Soak the plate in very hot water with a strong grease cutting dish soap, scrub with a soft brush, and rinse well. Repeat if needed; stubborn residue usually lifts within one or two hot soaks.
How often should I replace silicone feeding products?
There is no fixed schedule. Replace any item that is torn, permanently sticky after deep cleaning, or showing bite damage on parts that go in baby's mouth. With regular care, most silicone plates, bowls, and cups last for years.
