The simplest way to disinfect most baby toys that go in the mouth is a quick soak in diluted bleach: one tablespoon of unscented bleach per gallon of water, with at least two minutes of contact time. That’s the method the CDC recommends for childcare settings, and it works at home too. But the right approach depends on what the toy is made of, since plastic, silicone, wood, and fabric each need different handling to stay safe and intact.
Why Cleaning Matters More Than You Think
Bacteria like Staphylococcus aureus can survive on plastic surfaces for over 40 hours. Research from the University of Tennessee at Chattanooga found that on PVC, roughly 20% of staph bacteria were still alive after 20 hours, and measurable amounts persisted at the 40-hour mark. Babies mouth toys constantly, and those toys touch floors, shopping carts, and other kids’ hands. Regular disinfection, not just a rinse under the tap, is what actually reduces the germ load your baby encounters.
Hard Plastic and Rubber Toys
Most hard plastic teethers, rattles, and bath toys can be cleaned using one of three methods, depending on what you have on hand.
Bleach soak: Mix one tablespoon of plain, unscented bleach into one gallon of water. Submerge the toys and let them soak for at least two minutes. Rinse thoroughly with clean water and let them air dry completely. This is the CDC’s standard for early care and education settings, and at that dilution the residual bleach is negligible after rinsing.
Dish soap and hot water: For routine cleaning between deeper disinfections, scrub toys with warm water and regular dish soap. Pay attention to seams, crevices, and any holes where water (and mold) can get trapped. Bath toys with squeeze holes are notorious for growing mold inside. If you can’t clean the interior thoroughly, it’s worth replacing them.
Dishwasher: Many hard plastic toys are dishwasher safe. Place them on the top rack to keep them away from the heating element, and run a hot cycle. Skip the detergent pods with added fragrances if you can. Check the toy’s packaging first, since not all plastics hold up to high heat, and thin or cheaply made items may warp.
Silicone Toys and Teethers
Silicone handles heat extremely well, which makes it one of the easiest materials to sterilize. Bring a pot of water to a full boil, submerge the silicone toys, and let them boil for about three minutes. Remove them carefully and set them on a clean towel to cool and dry. This method kills bacteria, viruses, and fungi without any chemicals.
Silicone toys can also go in the dishwasher or be cleaned with the bleach soak described above. For day-to-day cleaning, warm soapy water and a good rinse are enough. The advantage of silicone is that it’s nonporous, so bacteria can’t embed into the surface the way they can with wood or fabric.
Wooden Toys
Wood is porous, which means it absorbs water and can harbor bacteria or mold if it stays damp. Never submerge wooden toys in water or put them in the dishwasher.
Instead, dip a clean cloth in a solution of warm water mixed with either a few drops of dish soap or equal parts water and white vinegar. Wipe down the entire surface of the toy, getting into any grooves or carved details. Then wipe again with a cloth dampened with plain water to remove any soap or vinegar residue.
Drying is critical. Let wooden toys air dry for at least 24 hours after cleaning. Moisture trapped in wood is a breeding ground for the very germs you’re trying to eliminate. Set them in a well-ventilated spot, not in a closed toy bin. If a wooden toy develops a musty smell, visible mold, or a rough, splintering surface, it’s time to throw it out.
Stuffed Animals and Fabric Toys
Plush toys that your baby mouths regularly need washing more often than you’d think. Most can go in the washing machine on a gentle or delicate cycle with a mild, fragrance-free detergent. Use warm or hot water if the care label allows it, since higher temperatures do a better job of killing germs.
For drying, low heat in the dryer works for most plush toys, though some with glued-on features or battery packs inside need to be air dried instead. Check for electronic components or music boxes before tossing anything in the machine. If a stuffed animal can’t be washed (some have internal mechanisms or delicate materials), wipe the surface with a damp cloth and soap, then let it dry completely in sunlight. UV light from the sun provides some natural disinfecting action.
How Often to Clean
Toys your baby mouths daily should get a soap-and-water cleaning a few times per week and a full disinfection (bleach soak, boiling, or dishwasher) at least once a week. Increase the frequency when your baby is sick, has been around other sick children, or when the toy has fallen on the ground in a public place. Toys used at daycare or playgroups deserve disinfection after every session.
If a toy hits the floor at home, a quick rinse with soap and water is usually fine. If it hits the floor at the grocery store or a doctor’s office, treat it like it needs a full cleaning before it goes back in your baby’s mouth.
What to Avoid
A few common mistakes can make toys less safe rather than more:
- Scented or antibacterial cleaners: These often contain chemicals you don’t want near your baby’s mouth. Stick with unscented dish soap, plain bleach solutions, or white vinegar.
- Skipping the rinse: Any cleaning solution, even a mild one, should be rinsed off thoroughly before the toy goes back to your baby.
- Putting toys away wet: A damp toy sealed in a bin or bag grows mold fast. Always let toys dry completely before storing them.
- Using the same sponge you wash dishes with: Kitchen sponges carry significant bacteria. Use a clean cloth or dedicate a separate sponge to toy cleaning.
Toys With Batteries or Electronics
Electronic toys can’t be submerged, boiled, or run through the dishwasher. Wipe them down with a cloth dampened in soapy water, then follow with a cloth dampened in your bleach solution (one tablespoon per gallon). Wring out the cloth well enough that no liquid drips into battery compartments or speaker holes. Wipe a third time with a damp, plain-water cloth to remove any residue, then air dry completely before giving it back to your baby.
