How to Keep Bath Toys Clean and Mold-Free: A Step-by-Step Routine

Quick answer

Squeeze and drain every bath toy right after the bath, then air-dry them fully before storing them loosely. Once a week, wash them in warm soapy water and use a diluted vinegar soak for extra hygiene. The real secret is drying, not scrubbing: mold in bath toys grows in trapped water, so any toy that stays sealed and damp will keep coming back to it.

Bath toys only stay hygienic if they can dry out between baths. The black specks people find inside squirting toys are mold and mildew feeding on trapped water and soap residue, and no amount of surface rinsing reaches them once they are sealed inside.

That is why bath toy hygiene is a drying routine first and a cleaning routine second. The steps below cover how to clean bath toys, how to use a vinegar soak safely, and how to store toys so water does not sit in them overnight.

Why mold grows in bath toys

A bath toy becomes a tiny aquarium: warm water, soap film, and a dark interior. Toys with a hole and no way for air to circulate hold that moisture for days, which is exactly what mold needs. The visible surface can look clean while the inside stays wet.

This is a design issue as much as a cleaning one. Toys that float or drain freely, like the Waylon Bath book - Sea creature / Sandy, have fewer hidden cavities than a classic squirter, so water leaves instead of pooling. Choosing toys with fewer sealed spaces cuts the problem at the source.

• If a toy has a hole you cannot open, treat it as a high-risk item and squeeze it dry after every single bath.
• A faint musty smell is the first sign; visible black spots mean the growth is already established.

How to clean bath toys with vinegar

For a weekly deeper clean, mix one part white vinegar with three parts warm water in a bowl. Submerge the toys and let them soak for 15 to 20 minutes, then squeeze the solution through any holes so it reaches the inside. Rinse thoroughly with clean water afterwards, because vinegar left on the surface can irritate sensitive skin.

Vinegar is a practical household option, but it is not a steriliser. If a toy has heavy black growth inside and cannot be opened or replaced, it is safer to retire it than to keep soaking it. Never boil, microwave, or dishwash a toy unless the manufacturer explicitly says it is safe to do so.

• Skip vinegar on plush or fabric toys; spot-clean those with mild soap and water instead.
• Keep the soak short and always rinse, especially on toys your baby chews.

Drying: the step most people skip

After every bath, squeeze or shake out each toy over the tub, then lay them on a towel or a slotted drainer rather than dropping them straight into a closed bin. Air needs to move around and through them. A small mesh bag hung over the tap works well for this.

Bath toys drying properly takes hours, not minutes. If you store them at night while still damp, you undo the whole routine. In humid bathrooms, run the fan or leave the door open so the room itself dries out.

• Stand hollow toys upside down so gravity pulls the last drops out.
• Give every toy at least one full air-drying cycle before it goes back in the bath.

Bath toy storage that lets air in

Bath toy storage should be open, not sealed. A basket, caddy, or mesh bag that drains and ventilates keeps air moving; a lidded plastic tub traps the humidity you just worked to remove. Keep the container off the wet floor of the tub and somewhere it can drip dry.

Rotate toys rather than keeping the whole collection in the bath at once. Fewer toys in the water means each one gets squeezed, drained, and dried properly. A simple two-basket system, one in use and one drying, makes the habit automatic.

• Choose a storage container with holes or open sides so moisture escapes.
• Wash the storage basket itself monthly, since it collects soap scum and residue.

Your weekly bath toy cleaning routine

1. 1. Empty the bath and squeeze every toy: As the water drains, squeeze or shake each toy over the tub so the dirty bathwater inside comes out. Do this before toys sit anywhere. Common mistake: leaving toys in the tub overnight, where they refill with water and start growing mold again.
2. 2. Rinse in clean warm water: Rinse off soap film and residue under running warm water, working it through any holes so the inside is flushed too. Checkpoint: the water running out should be clear, not soapy or grey.
3. 3. Air-dry upside down: Lay toys on a towel or slotted drainer, hollow side down, and let them dry completely, ideally overnight with the bathroom ventilated. Common mistake: towelling the outside and calling it dry; the inside is still wet.
4. 4. Do a weekly vinegar soak: Once a week, soak toys for 15 to 20 minutes in one part white vinegar to three parts warm water, squeeze the solution through the holes, then rinse thoroughly. Skip boiling, microwaving, or dishwashing unless the manufacturer states the toy is safe for it.
5. 5. Store loosely in an open container: Return fully dry toys to a basket, caddy, or mesh bag that lets air circulate, and keep only a small rotation in the bathroom at a time. Checkpoint: if you can smell mustiness when you open the container, something went in damp.
6. 6. Inspect monthly and retire what you cannot clean: Look inside hollow toys with a torch. If black growth is established in a sealed cavity you cannot open, replace the toy rather than soaking it again. Next step: note which toys keep failing and swap them for designs with fewer sealed spaces.

Products that make the routine easier

• Waylon Bath book - Sea creature / Sandy: A floating bath book that changes colour when immersed in water, with a light filling so it floats. Because it floats and has no sealed squirting cavity, it drains and air-dries far faster than a classic squirter, which lowers the risk of mold in bath toys.
• WESTON Medium Storage Box 2-Pack - Dove blue: Foldable, stackable medium storage boxes made from 60% recycled PP, with cutout handles. Useful for rotating toys out of the bathroom and keeping the dry set separate from the ones still air-drying.
• Dorian Baby Sensory Balls - Beach blue multi mix: Five soft silicone balls in different textures that double as teethers and are easy for little hands to grip. Silicone has no hidden interior to trap water, so a quick wash and towel-dry is enough, making it one of the easiest bath toys to keep hygienic.

Mold in bath toys is a water problem, not a scrubbing problem. Squeeze, rinse, dry fully, and store with airflow, and the weekly vinegar soak becomes a light top-up rather than a rescue mission.
