Cleaning a WubbaNub feels simple until you realize the plush is sewn on for good. If you've wondered how to clean wubbanub without soaking the fabric or trapping water inside, you're not alone. You can't toss the whole thing in the wash.
The answer comes down to treating the nipple and the plush as two separate jobs.
Manufacturer care guidance for the standard 0 to 6 month WubbaNub points to surface cleaning and thorough air drying, not machine washing. Per U.S. pacifier safety rules under 16 CFR Part 1511, the nipple also needs regular integrity checks. Get those two habits right and the rest of the routine falls into place.
How to Clean Wubbanub
Wipe the silicone nipple with warm water after every use. Spot clean the plush with a damp cloth and mild soap. Never soak or machine wash the sewn-in plush.
Blot it dry, then air dry completely before use. Replace the unit if the nipple tears or the plush smells musty.
Why a WubbaNub Is Harder to Clean Than a Regular Pacifier
A regular Soothie pacifier is one piece of silicone. You can rinse it, boil it, or run it through a sterilizer without a second thought. A WubbaNub adds a plush animal and a sewn-in ribbon, and that changes everything.
That's why the cleaning routine has to be gentler than what you'd use on a bare pacifier.
The sewn-in plush problem
The plush is attached permanently on standard models. There's no zipper, no removable cover, no way to separate fabric from silicone. Every cleaning decision has to protect both materials at once.
Hot water that's fine for silicone can shrink or warp the fabric. Soap that's safe for the plush can leave residue on the nipple your baby sucks on.
What the manufacturer's care label actually tells you
WubbaNub's own care guidance leans on surface cleaning and air drying. The sewn-in tag usually shows a hand wash symbol and a line dry symbol, not a machine wash icon. In our research, that label is the single most reliable starting point.
Follow it before you try any hack you saw online. If the tag is missing, default to the gentlest method possible.
Silicone Nipple vs. Sewn-In Plush: Two Different Cleaning Jobs
Think of a WubbaNub as two items sharing one body. The nipple needs the hygiene you'd expect from any pacifier. The plush needs the care you'd give a favorite stuffed toy.
Mixing those two jobs is where most cleaning mistakes start. Get the split right and cleaning becomes predictable.
What's inside the plush (and why that matters)
Inside the fabric shell is fiberfill, and some models add weighted pellets near the base. Both materials hold moisture far longer than silicone does. A plush that feels dry on the outside can still be damp at the core.
Squeeze gently and you'll often feel cool dampness even after a full day of air drying. That trapped moisture is what feeds mold and the faint musty smell parents complain about.
Where water gets trapped
Water sneaks in through seam gaps, the ribbon attachment point, and any small opening near the pacifier base. Once inside, it has almost nowhere to escape. Airflow is limited, and the fill acts like a sponge.
If you submerge the plush even once, plan on days of drying, not hours. That's why surface cleaning beats soaking every time.
The Daily Routine: Cleaning After Every Use
Daily cleaning is mostly about the nipple. The plush only needs attention when it actually gets soiled. Keep the routine short and you'll actually stick with it.
Two minutes of care after each use saves you a much bigger job later.
Cleaning the nipple
Rinse the silicone nipple under warm running water after each use. Rub it gently with clean fingers to lift milk residue. If it feels tacky, add a drop of mild fragrance-free soap, then rinse thoroughly.
Shake off excess water and let it air dry before the next feed or nap.
Spot-cleaning the plush
Mix a small amount of mild baby soap with lukewarm water. Dampen a soft cloth, wring it out well, and wipe the fabric surface. Work from the center outward so you don't push dirt into the seams.
Follow with a clean damp cloth to lift soap residue, then blot with a dry towel.
On-the-go cleanup that doesn't leave it damp
Pacifier wipes work for quick nipple cleanups in a diaper bag. For the plush, a barely damp cloth is safer than a wet wipe. Skip anything that leaves the fabric visibly wet.
A damp WubbaNub stuffed back into a bag is a mold risk waiting to happen.
The Deeper Clean: Washing the Plush Without Soaking It
Once a week, or after any spit-up or milk spill, the plush needs more than a quick wipe. The goal is to clean the fabric without pushing water inside. Slow and gentle wins here.
This is the step most parents rush, and it decides how long the WubbaNub lasts.
What you need
A soft microfiber cloth, mild fragrance-free baby soap, a bowl of lukewarm water, a clean dry towel, and a well-ventilated drying spot. Skip harsh detergents, bleach, and fabric softener. They leave residue and break down the fabric.
Step-by-step
- Mix a few drops of soap into lukewarm water. 2) Dampen the cloth and wring it until it's barely wet. 3) Wipe the plush surface in small circles, avoiding the seam gaps. 4) Rinse the cloth in clean water and wipe again to remove soap. 5) Blot with a dry towel. 6) Air dry completely, turning the toy every few hours. The cloth should be damp, not dripping.
Hard water and soap residue
Hard water leaves a mineral film that can make the fabric feel stiff. If you notice a chalky residue, wipe once more with distilled water. Soap residue is a bigger problem on the nipple than the plush.
Rinse the nipple longer than you think you need to.
Drying and Mold: The Step Most Parents Get Wrong
Drying is where a clean WubbaNub either stays safe or turns into a problem. Mold doesn't need visible water. It just needs a little trapped moisture and a few quiet hours.
Skip this step and you undo all the careful work from earlier.
How long it really takes
A surface-wiped plush usually needs 4 to 8 hours to dry fully, depending on humidity. In a damp bathroom or a rainy week, it can take overnight or longer. A plush that's still cool to the touch after a full day isn't dry yet.
A small fan or a sunny window speeds things up without adding heat.
The sniff test and what a musty smell means
A musty smell means moisture reached the fill and stayed there. You can't fix that with more soap. Trust your nose over how the fabric looks.
As of 2026, the CDC's mold guidance is clear that damp materials need to be dried or discarded. For a baby product, discarding is the safer call.
Why you can't clean mold out of fiberfill
Mold grows inside the plush, not just on the surface. Wiping the outside does nothing to the spores buried in the fill. Bleach or vinegar on the surface won't reach them either.
Once a WubbaNub smells musty, replace it. No cleaning method makes it safe again.
What Not to Do: Boiling, Dishwashers, Microwaves, and Machine Washing
Skip all four. Boiling, dishwashers, microwaves, and machine washing can each wreck a WubbaNub in one cycle. Manufacturer specs confirm the unit isn't built for heat or agitation.
The pacifier and the plush have different tolerances, and none of these methods respect either one.
Damage you can't undo
Boiling water softens the silicone nipple and can warp the shield. Dishwasher heat does the same, plus the detergent strips fabric dyes. A microwave heats unevenly and can melt the ribbon attachment.
Machine washing and drying beat up the fill, mat the fabric, and pull the plush out of shape. None of that is fixable.
| Method | What breaks | Verdict |
|---|---|---|
| Boiling | Nipple softens, shield warps | Never |
| Dishwasher | Heat plus detergent fade fabric | Never |
| Microwave | Uneven heat, melted tether | Never |
| Machine wash | Matting, shape loss, trapped water | Never |
| Damp cloth plus air dry | Nothing | Always |
Soaps and cleaners to skip near the nipple
Keep bleach, fabric softener, scented detergent, and disinfecting sprays away from the nipple. Residue there goes straight into your baby's mouth. If you use vinegar anywhere, keep it on the plush only and rinse it off fully.
Mild fragrance-free soap is all you need.
When to Replace It, and When to Just Throw It Out
Replace the whole unit when the nipple shows wear, and throw it out immediately if the plush smells musty. Those are two separate triggers, and both mean the same thing: it's done. WubbaNub guidance points to replacing a pacifier roughly every 4 to 6 weeks, sooner with heavy use.
The nipple pull test and wear signs
Gently tug the nipple away from the shield. It should hold firm with no stretching at the base. Look for tears, a tacky feel, cloudiness, or thinning.
Any of those means the silicone is breaking down. Retire it that day, not next week.
Replacement timing and pacifier rotation
Most families do well with two or three units in rotation. One gets used while another dries, and a third covers the wash day you forget. Rotating also spreads the wear, so no single unit hits the nipple failure point early.
Label them if you want to track which is oldest.
Pacifier safety standards
Per 16 CFR Part 1511, pacifiers must meet nipple strength and shield ventilation requirements. Per CPSC pacifier safety guidance, check regularly for cracks and never tie a pacifier around a baby's neck. For hand-me-downs, check CPSIA compliance and skip anything with unknown history.
Frequently Asked Questions
Can you put a WubbaNub in the dishwasher?
No. Dishwasher heat warps the shield, degrades the silicone nipple, and fades the plush fabric. The detergent is harsh on both materials too.
Hand cleaning with a damp cloth and mild soap is the only safe route. Air dry completely before the next use.
How often should you clean a WubbaNub?
Wipe the nipple with warm water after every use. Deep clean the plush about once a week, or right away after any spit-up or milk spill. In humid weather, dry it longer than you think necessary.
A musty smell means it's time to replace it.
Can you wash the plush part separately?
No, on standard models the plush is sewn on for good. There's no removable cover and no zipper. That's why surface cleaning and thorough air drying matter so much.
You're cleaning around a permanent attachment every single time.
How do you know a WubbaNub is fully dry?
It should feel room temperature and completely dry at the seams and ribbon base. Squeeze it gently. Any cool dampness means moisture is still inside the fill.
Give it a few more hours with airflow before storing or using it.
What if the WubbaNub already smells musty?
Throw it out. Mold grows inside the fiberfill where wiping can't reach it. Surface cleaners, vinegar, and sunlight only touch the outside.
No cleaning method makes a moldy plush safe for a baby again. Replacement is the only answer.
