Tackling Mould and Mildew in a Motorhome

Why Mould in Motorhomes Is a Problem

Anyone who owns a motorhome or camper van knows the ongoing challenge of tackling mould and mildew. It’s not just unpleasant to look at or smell – that musty odour can be difficult to live with – but it can also damage fixtures, fittings, and upholstery inside your vehicle.

More importantly, mould can cause health issues, especially for babies, young children, older adults, and people with underlying conditions.

Mould thrives in warm, humid environments, while mildew, a type of fungus, grows where there’s persistent moisture. That’s why both are common in kitchens, bathrooms, and enclosed spaces with poor airflow.

The good news is that there are straightforward steps you can take to prevent mould in a motorhome and keep your vehicle fresh and comfortable.

Improve Ventilation in Your Camper Van

Poor ventilation is one of the main reasons condensation builds up and mould appears. There are several ways you can reduce the risk of mould and mildew occurring through better ventilation.

• Keep windows open while cooking or showering, even during cooler months.
• Air your motorhome regularly if it’s in storage over winter.
• Check mattresses, cupboards, wardrobes, and under-seat areas for trapped moisture.
• Use dehumidifying sachets or moisture traps in storage spaces (replace them regularly).

Check for Leaks and Condensation

Even the smallest leak can create the perfect breeding ground for mould and mildew. 

• Stay on top of maintenance by inspecting sinks, taps, and pipes for corrosion or cracks.
• You should also check seals around windows, hatches, and roof vents, and resealing when needed.
• And remember to keep an eye on condensation inside the vehicle and wiping down wet surfaces promptly.

Regular checks can save you from costly repairs later.

Keep Your Motorhome Clean

A consistent cleaning routine makes it much harder for mould to develop.

• Give your motorhome a deep clean when bringing it out of storage.
• Clean up food spillages and disinfect kitchen surfaces.
• Empty and clean the fridge thoroughly before storage, and leave the door open if it won’t be used for a while.

Protect Soft Furnishings

Mattresses, cushions, curtains, and blinds all absorb moisture and are vulnerable to mildew. You can prevent issues by:

• Ensuring airflow around beds and seating.
• Checking fabrics regularly for damp patches.
• Washing and drying any items that show signs of mould before reusing them.

If mould does appear, treat it quickly with specialist cleaning products or safe household solutions like diluted hydrogen peroxide. Always wear protective gloves when handling strong cleaning agents.

How to Stop Mould Growth in Motorhomes

If you’ve spotted mould already, the priority is to stop it spreading. Taking swift action stops small outbreaks becoming a long-term issue that damages your motorhome.

• Identify the source 

Find and fix any leaks or areas of excess condensation.

• Remove visible mould

Use an appropriate cleaning solution, such as diluted hydrogen peroxide, white vinegar, or a proprietary mould remover.

• Dry the area thoroughly

Moisture left behind will encourage regrowth.

• Improve ventilation

Increase airflow to the affected area with open windows, vents, or a portable fan.

• Monitor regularly

Re-check problem areas every few days to ensure the mould has not returned.

Simple Steps for a Fresher Motorhome

By improving ventilation, tackling leaks quickly, and keeping your vehicle clean, you can minimise the risk of mould and mildew in your motorhome. With these preventative measures, your camper van will stay healthier, fresher, and ready for the next trip.
