Is Mould on a Pram Dangerous? (And How to Remove It)

You've pulled the pram out of the cupboard, opened it up, and there it is — dark spots on the fabric, a musty smell, and that sinking feeling. Mould on a pram is more common than you'd think, especially in the UK, and the first question every parent asks is the same: is it actually dangerous for my baby?

Is mould on a pram dangerous for babies?

The short answer: it can be, and you shouldn't ignore it.

Mould produces spores that become airborne when disturbed. For adults, occasional exposure to household mould is usually manageable. But babies and young children are more vulnerable for several reasons: their immune systems are still developing, they breathe faster than adults (inhaling more spores relative to their body size), and they're sitting with their face inches from the mould in a pram.

The NHS notes that mould exposure can cause respiratory symptoms including coughing, wheezing, and worsened asthma. For babies with developing lungs, this is a genuine concern — particularly with prolonged or repeated exposure.

Our honest advice: don't put your baby in a mouldy pram. Either clean it properly first, or get it professionally treated. The risk isn't worth it.

What causes mould on prams?

Mould needs three things to grow: moisture, warmth, and organic material to feed on. A pram provides all three:

• Moisture — from rain, damp storage, condensation, or not drying the pram after cleaning. Even residual dampness from a wet school run, folded away overnight, is enough.
• Organic material — food crumbs, milk spills, dribble, and sweat soaked into fabric give mould exactly what it needs to feed on.
• Poor ventilation — a folded pram stored in a cupboard, shed, or under a cover traps humidity and creates the perfect environment.

The most common scenario we see: a pram used in the rain, folded away slightly damp, stored in a cupboard or against an outside wall, and left for a few weeks. By the time it comes out, mould has established itself in the fabric, straps, and sometimes the foam padding inside.

Types of mould you might find on a pram

Not all mould on a pram looks the same:

• Black spots on fabric — the most common. Usually Aspergillus or Cladosporium. Appears as small dark spots, often on the hood, seat fabric, or around seams where moisture collects.
• White or grey fuzzy patches — often Penicillium. Usually found on stored prams, especially on fabric that was damp when put away.
• Green patches — often Aspergillus. Can appear on fabric and rubber/plastic components. More common in very damp conditions.
• Musty smell without visible mould — this usually means mould is growing somewhere you can't see, often inside foam padding or behind fabric panels. Just because you can't see it doesn't mean it's not there.

How to remove mould from a pram at home

If the mould is limited to surface spots on the fabric, you can try removing it at home. Here's the safe method:

1. Take the pram outside. You don't want to disturb mould spores indoors. Work in a well-ventilated area.
2. Brush off dry mould first. Use a soft dry brush to remove surface mould before wetting anything. This prevents the mould being pushed deeper into the fabric.
3. Make a cleaning solution. Mix warm water with a small amount of mild detergent. Do NOT use bleach — it damages pram fabric, fades colours, and the fumes are harmful for babies even after drying. White vinegar diluted 50/50 with water is a safer alternative that kills most mould species.
4. Scrub gently. Apply the solution with a soft cloth or brush. Work the affected areas without soaking the fabric through to the padding.
5. Rinse thoroughly. Wipe over several times with clean water to remove all cleaning residue.
6. Dry completely in sunlight. UV light is a natural mould killer. If you can, dry the fabric in direct sunlight for several hours. This is the most effective free mould treatment available.
7. Inspect after drying. If the stains remain or the musty smell persists, the mould has likely penetrated deeper than a surface clean can reach.

Important: This method works for surface mould only. If mould has grown into the foam padding, around seams, or behind panels you can't access, a surface clean won't eliminate it — it'll come back.

What about mould in foam padding?

This is the difficult one. Foam padding inside pram seats, headrests, and bumper bars is where mould does its worst damage — and where it's hardest to treat at home. The foam is porous, holds moisture, and once mould has grown inside it, surface cleaning won't reach it.

Signs that mould has reached the padding: a persistent musty smell even after surface cleaning, dark discolouration that shows through the fabric from behind, or mould spots that reappear within days of cleaning.

At home, your options are limited. You can try removing the padding (if possible), soaking it in a mild detergent solution, and sun-drying it for a full day. But honestly, if mould has penetrated foam padding, professional treatment with specialist products is the most reliable way to eliminate it completely.

How to prevent mould on your pram

Prevention is always better than treatment. Most pram mould is entirely avoidable:

• Never store a damp pram. If the pram got wet, open it up and let it air dry fully before folding and putting away. This single habit prevents 90% of pram mould.
• Clean regularly. Wipe down fabric and remove food crumbs after use. Mould needs organic material to feed on — a clean pram is much less likely to develop mould.
• Store properly. Keep in a dry, ventilated space. Avoid damp sheds, garages with poor airflow, or against external walls that get cold. Read our full guide on how to store your pram safely.
• Use a breathable cover. If you must cover the pram for storage, use a breathable fabric cover — not a sealed plastic bag, which traps moisture and accelerates mould growth.
• Consider fabric protection. A fabric protector spray (applied after cleaning) creates a barrier that repels moisture and makes future cleaning easier. We offer this as a £15 add-on to any clean.

When to replace your pram instead of cleaning it

In most cases, a mouldy pram can be saved with proper cleaning or professional treatment. But there are situations where replacement makes more sense:

• Structural mould damage — if mould has caused fabric to rot or weaken, especially on harness straps (this is a safety issue)
• Mould keeps returning despite professional cleaning — this suggests the mould has penetrated components that can't be adequately treated
• The pram was already near end of life — if it's heavily used and the mould is extensive, the cost of professional treatment may not be worth it versus replacing

For most prams though — especially premium brands like Bugaboo, Silver Cross, or iCandy — professional mould treatment is significantly cheaper than replacing a £500–1,200 pram. A professional clean with mould treatment costs £85 including collection and delivery.
