Mould on a Pronto Stroller Wagon is usually caused by trapped moisture, poor airflow, and high humidity. Even a clean wagon can develop mould when stored in a garage, shed, or enclosed space for extended periods.
The good news is that mould is often preventable. By ensuring your wagon is completely dry before storage, improving ventilation, and managing moisture levels, you can significantly reduce the risk of mould growth and help extend the life of your wagon.
Why Does Mould Develop on Stroller Wagons?
Mould thrives in damp, poorly ventilated environments. In humid climates and many coastal areas of Australia, moisture can linger in fabrics and hard-to-reach areas long after a wagon appears dry.
Common causes of mould include:
- Storing the wagon while it's still damp
- Wet seat liners, blankets, or accessories
- Poor airflow in garages or storage areas
- Humid weather conditions
- Plastic covers that trap moisture
- Long-term storage on concrete floors
Understanding these risk factors is the first step toward preventing mould before it starts.
Store Your Wagon Completely Dry
The most important thing you can do is make sure your wagon is fully dry before putting it away.
Before storage:
- Wipe away rainwater, condensation, or spills
- Ensure there are no food or drink spills on the seats (kids can be messy little creatures)
- Remove any wet accessories
- Allow seat fabrics and canopies to air dry
- Leave the wagon open for several hours after use in humid conditions
Even small amounts of trapped moisture can create an environment where mould can develop.

After Beach Trips and Rainy Outings
Salt air, wet towels, and unexpected rain showers can leave hidden moisture behind. Whenever possible, open the wagon and allow it to dry thoroughly before folding and storing it.
Avoid Plastic Covers
Many people cover their wagon to keep dust away, but plastic covers can do more harm than good. Plastic traps moisture and limits airflow, creating ideal conditions for mould growth.
Instead:
- Use a breathable fabric cover
- Store the wagon in a well-ventilated area
- Avoid sealing it completely unless the space is climate-controlled
A little airflow can make a big difference.
Improve Airflow in the Storage Area
Good ventilation helps moisture evaporate before mould has a chance to develop.
Simple ways to improve airflow include:
- Leaving a gap between the wagon and surrounding walls
- Storing it partially unfolded if space allows
- Opening garage doors on dry days to encourage air circulation
- Avoiding overcrowded storage spaces
The goal is to prevent moisture from becoming trapped around the wagon for extended periods.

Use Moisture Absorbers
If your garage or shed tends to feel damp, moisture absorbers can help reduce humidity levels. Place them near the storage area, following the manufacturer's safety instructions and keeping them out of children's reach.
For many, this simple addition can noticeably reduce moisture-related issues.
Keep the Wagon Off the Concrete Floor
Concrete naturally absorbs and releases moisture. Over time, this can increase humidity around anything stored directly on it.
Consider:
- Placing the wagon on rubber mats
- Using a storage platform
- Installing shelving
- Hanging it on suitable wall-mounted storage hooks
Raising the wagon off the floor can help improve airflow and reduce moisture exposure.
Inspect It Regularly
Even if the wagon isn't being used often, it's worth checking it every few weeks. A quick inspection can help you identify any issues before they become difficult to remove.
What to Check
- Seat pads and fabric folds
- Harness straps
- Storage baskets
- Canopy seams
- Fold joints and hinges
- Rain covers stored in pockets
If you notice any suspicious spots, clean them immediately using a manufacturer-approved cleaner or a mild vinegar solution where appropriate.

Consider a Small Dehumidifier
If your storage area regularly feels damp, a small dehumidifier can be a worthwhile investment.
Benefits include:
- Lower humidity levels
- Reduced risk of mould growth
- Better protection for baby gear and household items
- Improved storage conditions year-round
Many families find that a dehumidifier helps protect not only their wagon, but also bikes, tools, camping equipment, and other stored items.
Areas Most Commonly Affected by Mould
Mould often develops in hidden areas where moisture collects and airflow is limited.
Pay particular attention to:
- Under seat cushions
- Harness webbing
- Canopy stitching and seams
- Fold joints
- Storage baskets
- Rain covers and accessories
- Fabric folds around the frame
These areas are easy to overlook but are often the first places mould appears.
A Simple Reminder That Can Prevent Bigger Problems
Many parents assume mould only develops on dirty products. In reality, moisture is usually the main culprit.
A few simple habits can go a long way:
- Dry the wagon after wet weather
- Air it out after beach trips
- Avoid long-term storage while damp
- Check hidden areas regularly
- Improve ventilation wherever possible
Mould prevention doesn't require expensive products or complicated maintenance. In most cases, ensuring your Pronto Stroller Wagon is dry before storage, improving airflow, and checking it regularly will help prevent problems before they start.
A little preventative care can help keep your wagon looking its best and performing reliably for years to come.
