How Do You Get Rid of Mould in Your Caravan or Boat?

How Do You Get Rid of Mould in Your Caravan or Boat?

, by Aussie Pharma Direct, 7 min reading time

Whether it's a leisurely caravan trip through the Outback or a serene day sailing along the stunning Australian coastline, caravans and boats serve as beloved retreats for many Australians. We spend countless hours within these mobile havens, reading under the awning, enjoying meals with loved ones, or simply gazing at the passing scenery.

But amidst all that, when it comes to maintaining our vehicles, we often prioritise the mechanical aspects—the engine, the hull, or the tires—while overlooking the interior spaces where we actually spend our time.

Unlike our permanent homes, the insides of caravans and boats are susceptible to unique challenges. They face fluctuating temperatures, condensation build-up, and limited ventilation, creating an ideal breeding ground for a silent enemy – mould.

And this is where we’re going to be guiding you on mould removal in caravans and boats, answering every question you might have about identifying, tackling, and preventing them.

What are the signs of damp in a caravan or boat?

Here are some common signs to watch out for:

1. Musty odour

A musty smell is often the first indication of dampness. The enclosed nature of boats and caravans can exacerbate odours, making it easier to detect any moisture-related issues.

2. Visible mould or mildew

Keep an eye out for any visible signs of mould or mildew on walls, ceilings, floors, or furnishings. Mould typically appears as black, green, or brown patches and can grow in areas with high humidity or moisture levels.

3. Water stains

Look for water stains on walls, ceilings, or upholstery. These stains may indicate leaks or condensation problems that contribute to dampness.

4. Damp or wet surfaces

Check for damp or wet surfaces, particularly in areas prone to moisture buildup such as corners, around windows, or near plumbing fixtures. Moisture on walls, floors, or furnishings suggests an underlying issue that needs attention.

5. Peeling or bubbling wallpaper or paint

Moisture can cause wallpaper or paint to peel, bubble, or crack. Examine the walls and ceilings for any signs of deterioration, as these may indicate water damage and potential dampness.

6. Soft or spongy floors

Dampness can weaken the structure of the caravan floor, causing it to feel soft, spongy, or uneven in certain areas. It can also weaken the structural components of a boat, leading to soft or spongy areas on decks, cabin floors, or bulkheads. Walk around the caravan or boat and pay attention to any changes in floor texture or stability.

7. Condensation on windows

Condensation buildup on windows or portholes, particularly in cold weather or humid conditions, is a common sign of poor ventilation and excess moisture inside the caravan.

How do you get rid of mould in your boat or caravan?

When it comes to combating mould in enclosed spaces like boats or caravans, natural and eco-friendly solutions have gained popularity for their effectiveness and safety. While bleach is often the go-to solution, it's essential to understand its limitations. While bleach can remove visible mould stains, it doesn't effectively kill the mould spores, leaving behind potential for regrowth.

In contrast, plant-based and enzyme-based mould removers offer a more comprehensive approach by both removing visible stains and killing mould at its source. Plant-based mould removers harness the antimicrobial properties of essential oils and botanical extracts to kill mould spores and inhibit growth, while enzyme-based cleaners break down mould stains through biological processes. These non-toxic alternatives offer a safer and more environmentally friendly approach to mould remediation. 

Now, here’s a guide for effectively cleaning and killing mould in your boat or caravan:

  1. Before you begin, make sure to wear protective gear such as gloves, a mask, and goggles to prevent any contact with mould spores.
  1. Open all windows and doors to allow fresh air to circulate through the caravan or boat. This helps in reducing the concentration of mould spores in the air.
  1. Take out any removable items from the caravan or boat such as cushions, curtains, bedding, and clothing. These items may have mould growth and need to be cleaned separately.
  1. Use a vacuum cleaner with a HEPA filter to remove loose mould spores from surfaces and fabrics. Pay special attention to areas where mould is visible.
  1. Consider using natural solutions like vinegar or baking soda to clean mould. Alternatively, you can use SAN-AIR™ Surface Mould Remover so you don’t have to go through the hassle of measuring or mixing solutions together to save time. 

We’ve mentioned before about natural solutions to effectively kill mould at its source. SAN-AIR™ Mould Remover products are made with 100% natural actives that are highly effective in killing mould, mildew, bacteria, and germs.

To clean with SAN-AIR™ Surface Mould Remover:

  • Spray surface mould remover evenly to coat the mould-infected area.
  • Allow the solution to sit for 15 minutes.
  • After the waiting period, use a clean, dry cloth to wipe off the mould. Ensure thorough cleaning, and do not reuse dirty cloths to prevent the spread of mould. For each wipe, use a clean area of the cloth until it is used up, then continue with a new clean cloth.
  • If any mould residue remains, repeat the application and wiping process until all traces of mould have been completely removed from the surface.
  • Give the cleaned surface a final spray with a fine mist of SAN-AIR™ Surface Mould Remover. Allow it to air dry naturally.

How to prevent mould regrowth in your caravan or boat?

Preventing mould regrowth in your caravan or boat involves a combination of regular cleaning, moisture control, and proper ventilation. Here are some tips:

  • Use dehumidifiers or moisture absorbers to maintain low humidity levels inside your caravan or boat. Fix any leaks promptly to prevent water buildup.
  • Proper ventilation is essential for preventing mould. Ensure that your caravan or boat is well-ventilated by opening windows and hatches regularly, especially after cooking, showering, or any activity that generates moisture.
  • When renovating or furnishing your caravan or boat, opt for materials that are resistant to mould, such as mould-resistant paints, fabrics, and flooring. Check with your local hardware store for these products. 
  • Check seals around windows, doors, hatches, and vents regularly for any signs of wear or damage. Repair or replace seals as needed to prevent water intrusion.
  • Store clothing, bedding, and other items in airtight containers or vacuum-sealed bags to prevent moisture buildup. Avoid storing damp or wet items inside your caravan or boat.
  • Whenever possible, expose your caravan or boat to sunlight. Sunlight helps to inhibit mould growth and can help dry out damp areas.
  • Consider using mould inhibitors or treatments specifically designed for marine or caravan use.

Need to close your caravan or boat for a long time until your next adventure?

You can actually use mould inhibitors like the SAN-AIR™ Caravan, Boat & Storage Reactive Gel. This stuff is made from natural ingredients and has a smart formulation that cuts off mould's oxygen supply, stopping it from coming back. The best part? You don't have to keep going back to your caravan or boat for constant cleaning. Just apply this gel, and it'll keep things mould-free for up to 3 months, perfect for those long stretches between road trips or vacations.
