Owning an RV often means countless adventures and cherished family memories, but dealing with mold is a far less enjoyable experience. Mold is unsightly and damaging to your vehicle. Worse yet, it can impact the health of your loved ones.
Fortunately, with a bit of preparation and the right strategies, you can prevent mold in your stored RV and feel ready for the next trip.

1. Use Dehumidifiers To Control Moisture
Moisture and mold go hand in hand. A portable dehumidifier or two, depending on your RV’s size, is a smart investment for anyone storing their vehicle in humid climates. Regularly empty and clean your dehumidifier so it works at full capacity.
Alternatively, use moisture-absorbing products like silica gel packets, which work wonders in enclosed spaces like RV cabins. Place the packets in high-risk areas like the sitting area, bathroom, and kitchen.
2. Inspect and Maintain Seals To Prevent Leaks
Even the tiniest leak causes big problems, so routine inspections are a must. Weather has an impact on stored RVs, especially in the form of rain that leads to moisture infiltration and promotes mold growth.
Check the seals around your windows, doors, roof, and vents for signs of wear or cracks. Replace or refresh weather stripping and caulking as needed so they’re watertight. Don’t forget to examine your roof for damage after heavy weather or prolonged exposure to the sun.
3. Store Items Strategically To Allow Airflow
Storage is a pivotal part of any RV experience and determines how well you can prevent mold growth. Avoid cramming cabinets from wall to wall with belongings; leave some breathing room for air to flow. Use plastic bins or vacuum-sealed bags to keep clothing, linens, and other fabrics dry.
Incorporating multipurpose furniture for storage and style is a budget-friendly RV upgrade. If you have mattresses or cushions, consider propping them up so air circulates underneath. A little organization goes a long way—plus, it makes unpacking for your next trip so much quicker!
4. Stick to a Regular Cleaning Routine
Maintaining a clean RV is one of the easiest and most effective steps to keep mold in check. Before storing your motorhome, thoroughly clean it, paying special attention to damp-prone areas like the bathroom, kitchen, and under-sink cabinets.
Wipe down hard surfaces with a mild bleach solution or a commercial anti-mold spray to kill existing spores. Don’t forget to clean and dry the carpets, curtains, and air-conditioning vents, as these often trap moisture. Follow this up with a quick monthly check while your RV is in storage.
A little preparation now saves you a lot of time, effort, and money later on. Use these tips to prevent mold in your RV. These simple steps will protect your investment so it’s always ready for your next big adventure.
