Bath time is supposed to wash everyone clean, not introduce mystery science experiments hiding inside your baby's favorite rubber duck.
The truth is, bath toys spend their lives in the perfect environment for mold: warm, wet, and humid. Fortunately, a few simple habits can help keep them cleaner, safer, and lasting much longer.

Why Do Bath Toys Mold?
Mold and mildew love moisture.
When water gets trapped inside bath toys, especially squirting toys, it creates the perfect breeding ground for bacteria and mold. Even clean bathwater contains soap residue, body oils, and naturally occurring microorganisms that can build up over time.
The longer moisture stays trapped, the faster mold can grow.
1. Dry Them Completely After Every Bath
This is the single best thing you can do.
After bath time:
- Shake off excess water.
- Squeeze squirting toys until no more water comes out.
- Leave toys where air can circulate around them.
Instead of leaving toys piled in the tub, use:
- Mesh storage bags (JoolBaby Storage Bag)
- Hanging baskets
- Drainable toy organizers
Airflow is your best friend.

2. Don't Let Toys Sit in the Tub
Even after the bath is over, the tub often stays damp for hours.
Leaving toys in puddles or wet corners gives mold another opportunity to grow.
Instead, move toys somewhere they'll dry quickly between baths.
3. Clean Bath Toys Weekly
Regular cleaning helps remove soap scum, bacteria, and buildup before they become a bigger problem.
Try one of these methods:
Warm Soapy Water
Wash toys with mild dish soap and warm water.
Rinse thoroughly and allow them to air dry.
White Vinegar Solution
Mix:
- 1 part white vinegar
- 3 parts warm water
Soak toys for about 15–20 minutes before rinsing well.
This helps remove mineral buildup and discourage mold growth.
4. Give Squirting Toys Extra Attention
Squirting toys are often the first to develop mold because water gets trapped inside.
After every bath:
- Squeeze out as much water as possible.
- Repeat several times.
- Let the opening face downward while drying.
If black specks begin coming out when squeezed, it's usually time to replace the toy.

5. Choose Bath Toys That Are Easier to Clean
Not all bath toys are created equal.
When buying new ones, look for:
- Sealed toys that don't allow water inside
- Toys that fully open for cleaning
- Smooth surfaces without hard-to-reach crevices
- Durable materials that tolerate regular washing
These designs typically stay cleaner and last longer.
6. Inspect Toys Regularly
Even with excellent care, bath toys don't last forever.
Check them often for:
- Cracks
- Tears
- Discoloration
- Sticky residue
- Mold inside squirting toys
If a toy can't be cleaned thoroughly, replacing it is the safest option.
How Often Should You Replace Bath Toys?
It depends on how often they're used and how well they're maintained.
Many bath toys can last for years with proper care, but squirting toys and toys that trap water may need replacing sooner if mold develops or cleaning is no longer effective.
When in doubt, trust what you see. If mold is visible inside a toy or continues to return after cleaning, it's time for a replacement.
The Bottom Line
Keeping bath toys in great condition doesn't require a complicated routine. A few minutes after each bath can dramatically extend their lifespan.
