Moldy bath toys? Why it happens, mold-free bath toys, and easy cleaning & storage

Ever squeezed a rubber duck and watched black specks come out? Bath toys live in a warm, wet room, so mold loves them.

Here’s why it happens, which toys stay mold-free, and the simple cleaning and storage habits that keep them fresh.

Why bath toys get moldy

Mold grows where there’s moisture, soap residue and warmth. Squirt toys suck in water, and the soapy water left inside lets mold grow where you can’t see it.

Choose toys with no holes

“Mold-free” bath toys with no holes or seams are the easiest fix: water can’t get trapped inside.

Daily care

After the bath, rinse off soap and shake off the water. Squeeze out any water from toys with holes and let them dry.

Now and then, dry them outside the bathroom where there’s good airflow.

If you use a cleaner or bleach, check the labels for the toy and the product, and rinse well. Never mix different cleaners (for example chlorine bleach and acidic cleaners) — it can be dangerous.

If black spots won’t come off, it’s time to replace the toy.

Storage that drains

Don’t leave toys sitting on the floor. A wall-mounted basket or net that drains lets them dry quickly and keeps slime away.
