How to Prevent Mold from Growing on Your Kids’ Toys

When it comes to our children, we pay attention to everything; what they eat, where they sleep, and how they play. But one common household hazard that often flies under the radar is mold growing on children's toys. While it might sound like something out of a horror story for parents, it’s an all-too-common issue that can pose health risks if not dealt with properly. Whether it's that beloved rubber ducky floating in the tub or the trusty teething ring your baby gnaws on daily, some toys can become prime breeding grounds for mold if not properly cleaned and maintained.  

Here we’ll explore why mold grows on toys, which types of toys are most at risk, how to prevent mold growth on toys, what to do if you do find mold, as well as some safer options for your child’s playtime.  

Why Does Mold Grow on Toys?

Mold thrives in warm, damp, and poorly ventilated environments, exactly the kind of conditions many children's toys are regularly exposed to. Bath time favourites like rubber ducks, squirt toys, and foam letters often trap water inside, creating a perfect habitat for mold to flourish. Similarly, teething toys and soft plush toys can absorb saliva, milk, or drool, adding moisture and organic matter that mold spores love.

In many cases, the problem isn't immediately visible. Mold can grow inside toys, especially those with small holes or hollow interiors, making it hard to detect until you squeeze the toy and something unpleasant leaks out, or you notice a musty smell.

Toys Most at Risk of Mold Growth

Some toys are simply more prone to mold than others due to their design and the materials they're made from. The biggest offenders include:

• Bath Toys: Especially rubber or plastic toys with holes (like squeaky toys or squirt guns). Water can get inside and stay trapped, even after drying the toy's exterior.

• Teething Toys: Soft silicone or rubber toys that babies chew on frequently can collect saliva and are often not cleaned as often as needed.

• Plush Toys: Stuffed animals can soak up moisture from spills, drool, or even humidity. Unless machine washable and fully dried, mold can take hold.

• Foam Toys: Foam letters, bathmats, and building blocks may retain water and are difficult to dry completely.

How to Prevent Mold from Growing in Toys

Prevention starts with awareness and a regular cleaning routine. Here are some practical tips to reduce the risk of mold on your child’s toys:

1. Avoid Toys with Holes for Bath Time: Or if you do use them, seal the holes with hot glue before use to prevent water from getting inside.

2. Clean Toys Regularly: Use a child-safe disinfectant or a solution of vinegar and water. For bath toys, a soak in white vinegar followed by thorough rinsing works well.

3. Dry Thoroughly: Mold thrives in moisture, so ensure toys dry completely between uses. Leave them in a well-ventilated area and avoid storing them in damp bathrooms or toy bins.

4. Use Mesh Storage: For bath toys, a mesh bag allows air circulation and helps them dry faster than plastic bins.

5. Rotate Toys: Giving certain toys a break not only helps with hygiene but also reduces constant exposure to moisture.

6. Check Labels: Some toys are dishwasher-safe or machine washable. Take advantage of that for a deeper clean.

What to Do If You Find Mold on Your Child’s Toys

If you spot mold on a toy, act fast. Here’s what you should do:

• Soft or Porous Toys (e.g., plush, foam): Unfortunately, if mold has penetrated the material, it's safest to discard the toy. Mold roots can go deep, and even washing might not fully eliminate it.

• Hard Plastic or Rubber Toys: If the mold is only on the surface or inside a hollow toy, you can often clean and salvage it. Use a mix of white vinegar and baking soda. Soak, scrub, and rinse thoroughly. Allow to dry completely before returning it to your child.

• Persistent Mold: If you’ve cleaned it and it still smells musty or shows signs of mold returning, it’s best to throw the toy away.

Also, keep in mind that some children are more sensitive to mold exposure than others. Mold can cause respiratory problems, allergic reactions, and skin irritation, especially in children with asthma or compromised immune systems.

Toy Materials Less Likely to Grow Mold

Some toys are inherently less prone to mold because of their materials or design. Look for:

• Solid Hard Plastics (without holes): Easier to clean and less likely to trap moisture inside.

• Silicone Toys (one-piece design): Especially when they're dishwasher-safe and don't have crevices.

• Wooden Toys (sealed and finished): Natural wood has antimicrobial properties, and when properly sealed, it resists moisture buildup. However, unfinished wood should be kept away from water.

• Machine-Washable Plush Toys: Toys labeled as fully machine washable (and dryer-safe) are easier to maintain mold-free.

Mold on children’s toys may be an unsettling discovery, but it's preventable with the right habits. Understanding why mold forms, and choosing the right types of toys, can go a long way in protecting your child’s health and keeping their playtime safe. Regular cleaning, proper drying, and smart storage make a big difference. And if mold does appear, knowing how to clean or when to toss a toy helps you act with confidence.

Ultimately, a little diligence goes a long way. Mold might be sneaky, but with the right approach, you can keep it far away from your child's favourite things.
