Eradicating Mold From Your Camper Trailer: A Step-By-Step Guide

If you're an RV owner, you've probably already experienced the dreaded mould, mildew, and dry rot. These issues, if left untreated, can quickly take over your vehicle, leaving you with serious and costly problems. Mould can form on the inside and outside of your RV, and while exterior mould is not as urgent, it should still be addressed as soon as possible. Mould can cause serious health issues, such as respiratory illnesses, and can compromise your health if not dealt with. In this article, we will discuss how to get rid of mould in your camper trailer, as well as prevention methods to keep your RV mould-free.

Identify the source of the moisture

To identify the source of moisture in your camper trailer, you should start by inspecting the interior and exterior for any signs of mould growth or structural problems. Look for black or green discolouration on surfaces, bulges or bumps under the drywall or paint, and musty or earthy smells. These are all indicators of mould growth.

Next, check for any cracks or leaks that may be allowing moisture inside. Pay close attention to pipes, roof, plumbing, sinks, toilets, and ceilings. If you find any damage, fix it as soon as possible to prevent further moisture intrusion.

Another way to identify the source of moisture is to use a moisture meter, which can help you detect areas of high humidity or water intrusion. Open up suspected wall sections to inspect for moisture and ensure that all seals, including door, window, and vent seals, are intact and functioning properly.

Additionally, consider investing in a hygrometer to monitor the humidity levels in your camper trailer. Humidity levels should ideally be maintained between 30% and 50%.

By regularly inspecting your camper trailer, fixing any leaks or damage, and monitoring humidity levels, you can effectively identify and address sources of moisture, helping to prevent mould growth and maintain a comfortable and safe environment.

Clean with a DIY solution of hot water, dish soap, and vinegar

To get rid of mold in a camper trailer, you can create a DIY solution of hot water, dish soap, and vinegar. Here's a detailed, step-by-step guide on how to effectively clean and remove mold using this method:

Step 1: Prepare the DIY Cleaning Solution

Mix a gallon of hot water with a cup of powdered dishwashing detergent and a dash of vinegar. The hot water will help to dissolve the soap and create an effective cleaning solution. Dish soap is a great option for cleaning as it cuts through grease and grime, while vinegar is a natural disinfectant and mild acid that can help kill mold and mildew.

Step 2: Apply the Solution to the Affected Areas

Using a spray bottle, generously apply the cleaning solution to all moldy surfaces in your camper trailer. Make sure to wear protective gear, such as rubber gloves and a face mask, to avoid direct contact with the mold. If the mold is on the walls, start from the top and work your way down to prevent dripping and streaking.

Step 3: Let the Solution Sit

Allow the cleaning solution to sit on the surfaces for at least 15 minutes. This gives the solution time to penetrate and break down the mold and mildew. The vinegar in the solution will also help to eliminate any unpleasant odors caused by the mold.

Step 4: Scrub and Rinse

After the waiting period, use a moderately stiff-bristled brush or a damp cloth to scrub and wipe away the mold. Rinse the surfaces with clean water to remove any residue from the cleaning solution. For more stubborn mold stains, you may need to repeat this process until the stains are completely removed.

Step 5: Dry the Camper Trailer

Once you've finished cleaning, it's important to dry the camper trailer thoroughly. Use towels or cloths to wipe down all surfaces and speed up the drying process. You can also open the windows and doors of the camper trailer to allow for proper ventilation and airflow. If possible, park the trailer in direct sunlight to help inhibit further mold growth.

Additional Tips:

• It's important to address the cause of the mold to prevent it from returning. Check for any leaks, cracks, or areas of moisture buildup and make the necessary repairs.
• Regular cleaning and maintenance of your camper trailer will help prevent mold and mildew from taking over.
• If the mold problem is extensive or difficult to access, consider seeking professional help to ensure thorough mold removal and remediation.

Use bleach for nonporous surfaces

Bleach can be an effective way to remove mold from nonporous surfaces in your camper trailer. Here's a step-by-step guide on how to use bleach to get rid of mold:

Step 1: Identify the Mold

Before you begin the cleaning process, it's important to identify the extent of the mold problem. Look for signs of mold growth, such as black or green discoloration, musty odours, or bulges on surfaces. Inspect walls, ceilings, floors, and areas around windows, doors, and vents, as these are common entry points for mold spores.

Step 2: Prepare the Cleaning Solution

For this method, you'll need to mix a solution of bleach and water. The ratio of bleach to water may vary depending on the severity of the mold problem. As a general guideline, mix one part bleach with three parts water. Always exercise caution when handling bleach, and ensure the area is well-ventilated during the cleaning process.

Step 3: Protect Yourself

When working with bleach, it's important to take the necessary safety precautions. Wear protective gear, including rubber gloves, safety goggles, and a respirator mask. If possible, open windows or use fans to improve ventilation and reduce the concentration of bleach fumes.

Step 4: Apply the Bleach Solution

Using a spray bottle, generously apply the bleach solution to the affected nonporous surfaces. Ensure that you thoroughly saturate the moldy areas. Let the solution sit for a few minutes to allow it to penetrate and kill the mold spores.

Step 5: Scrub and Wipe

After allowing the bleach solution to sit, use a scrub brush or a damp cloth to scrub away the mold. Pay close attention to corners, crevices, and other areas where mold may be stubborn. Continue scrubbing until all visible traces of mold are removed.

Step 6: Rinse and Dry

Once you've finished scrubbing, use clean water to rinse the surfaces. This will help remove any remaining bleach residue. After rinsing, use towels or a wet-dry vacuum to dry the surfaces thoroughly. It's important to ensure that the area is completely dry, as moisture can promote mold regrowth.

Step 7: Disinfect and Deodorize

To prevent mold from returning and to eliminate any lingering odours, use a disinfectant spray on the cleaned surfaces. Alternatively, you can use a natural disinfectant like vinegar or tea tree oil. Allow the disinfectant to air dry.

Step 8: Address the Source

Now that you've removed the mold, it's crucial to address the source of the problem. Look for any leaks, condensation issues, or areas of water intrusion. Repair any leaks, improve ventilation, and consider using a dehumidifier to reduce moisture levels in your camper trailer. Regular maintenance and inspections can help prevent future mold problems.

Seal and repair leaks

To prevent mould in your camper trailer, it is important to seal and repair leaks. This process can be done in several steps.

Firstly, it is important to inspect your camper trailer for any signs of damage or leaks. Check the interior and exterior for any structural problems, such as rust, discolouration, bubbling, or cracks that may allow moisture inside. Pay close attention to pipes, the roof, plumbing, sinks, toilets, and the ceiling. If you identify any damage, it is crucial to fix these issues as soon as possible.

Next, you will need to clean the existing seals. Wear gloves and use acetone to clean the seals, turning them from a dirty grey or black to a clean off-white colour. This step will help you identify any seal breaks or potential leaks. Test the sealant by pushing a blunt pencil end into it; good sealant will be pliable and soft, while bad sealant will be dry, hard, and brittle.

Once you have identified any problem areas, it is time to repair the broken seals. Carefully remove the old sealant using a putty knife or metal brush. Clean the area with acetone, and then reseal using a high-quality sealant like Sikaflex 715 or 521, which are recommended by industry experts. These sealants are flexible and able to cope with the structural movement of your camper trailer. Apply the sealant evenly with a caulk gun and then smooth it out with your fingers.

After repairing all the identified leaks, it is a good idea to test your work. One way to do this is by using a SealTech machine, which pressurises the interior of your camper while spraying soapy water on the seals to check for any remaining leaks. If you find any, simply repair them following the previous steps.

Finally, it is important to make seal inspection and maintenance a regular part of your camper trailer care routine. At least once a month, check the seals on your roof and side walls for any signs of damage or wear and tear. By being proactive and addressing any issues promptly, you can prevent mould and moisture problems in your camper trailer.

Use a dehumidifier

Using a Dehumidifier to Get Rid of Mold in a Camper Trailer

Using a dehumidifier is an effective way to prevent and get rid of mold in a camper trailer. Dehumidifiers work by reducing moisture in the air, creating an environment that inhibits mold growth and helps to dry out any existing mold.

Types of Dehumidifiers

There are two main types of dehumidifiers: electric and desiccant. Electric dehumidifiers are plug-in units that use electricity to power a fan and remove moisture from the air. Desiccant dehumidifiers, on the other hand, use specialized crystals to absorb moisture without the need for electricity. Both types can be effective in a camper trailer, but electric dehumidifiers may be more suitable if your storage location has access to electricity.

When to Use a Dehumidifier

Dehumidifiers are particularly useful if you often camp in humid locations or during the winter months when there is a higher risk of condensation. It is recommended to run the dehumidifier for a few days before putting your camper trailer into storage and to monitor the humidity levels using a hygrometer. The ideal humidity level in your camper trailer should be between 30% and 50%.

Benefits of Using a Dehumidifier

• Dehumidifiers help to reduce moisture in the air, preventing mold growth and inhibiting the spread of existing mold.
• They can be used during storage to maintain a dry environment and prevent mold from forming.
• Dehumidifiers can also be used after cleaning to aid in the drying process and prevent the return of mold.
• Portable dehumidifiers are lightweight and compact, making them easy to use in small spaces like camper trailers.

Considerations When Using a Dehumidifier

• Dehumidifiers consume a significant amount of energy, so it is important to keep an eye on propane levels if using an electric dehumidifier.
• Dehumidifiers can be costly in terms of fuel and electricity consumption, so consider your budget when deciding to use one.
• While dehumidifiers are effective in reducing moisture, they should be used in conjunction with other mold prevention techniques such as proper ventilation, wiping wet surfaces, and regular inspections.
