Removing Mold Smell From Your Camper: A Step-By-Step Guide

If you're struggling with a mouldy-smelling camper, there are several steps you can take to tackle the issue. Firstly, identify and fix any leaks, as they contribute to moisture buildup and mould growth. Increase ventilation by opening windows and vents, and use dehumidifiers to reduce humidity levels. Clean and dry upholstery, carpets, curtains, and cushions, as dirt and spills can provide a breeding ground for mould. Use natural odour absorbers like baking soda, activated charcoal, or coffee grounds, and consider deep cleaning your refrigerator and holding tanks. If mould is visible, use distilled vinegar or hydrogen peroxide to kill it, and repair any water damage to prevent future moisture issues.

Air it out

Airing out your camper is one of the easiest ways to get rid of a musty smell. Open all the windows, screens, doors, and roof vents to let fresh air circulate. You'll notice a difference right away.

If your camper has been closed up for an extended period, the air inside becomes stagnant, allowing odors to accumulate. Airing out the camper will help eliminate this stagnant air and reduce the musty odor.

If possible, leave the camper open for a while to allow for thorough ventilation. This is especially important if your camper has been in storage or closed up for a long time.

In addition to airing out the camper, you can also utilize fans to keep the air moving and prevent moisture buildup, which can contribute to mold and mildew growth.

While airing out your camper, you can also place bowls of baking soda, activated charcoal, or coffee grounds in different areas of the camper to absorb odors. These natural odor absorbers can help neutralize the musty smell.

If the musty smell is due to mold or mildew, it's important to address the source of the moisture and fix any leaks or water damage. Identify and repair any leaks, and consider using a dehumidifier or moisture absorber to reduce humidity levels and prevent future mold growth.

By combining airing out your camper with other odor-removal strategies, such as cleaning and odor absorbers, you can effectively eliminate the musty smell and create a fresh and inviting space.

Clean fabrics and porous surfaces

To get rid of mould in your camper, you'll need to clean fabrics and porous surfaces. The first step is to identify and fix any leaks, as leaks can contribute to moisture buildup and mould growth. Inspect your camper for any signs of leaks and repair them promptly. Remove and wash any fabrics that can be washed, such as mattress covers, dinette covers, and curtains. Use a sports detergent that is specifically for removing tough odours.

For fabrics that can't be washed, use a steam cleaner or spray them with an odour eliminator. You can also try sprinkling baking soda on the fabric, letting it sit, and then vacuuming it off. If the fabric is outside in the sun, this can also help to get rid of the smell.

Mattresses and cushions can be hosed down and soaked with a vinegar solution, as vinegar is an effective cleaning agent for killing mildew and mould. You can also place items in direct sunlight, as the sun does wonders for getting rid of a musty camper smell.

If the smell persists, you may need to replace some items. For example, if your dinette table still smells after a good scrub, you can buy or make a new tabletop.

Use vinegar and baking soda

Vinegar and baking soda are a powerful combination to get rid of mold and mildew smells. While vinegar is an effective mold killer, baking soda is a natural cleaner that can be used to kill mold and neutralize odors. Here is a step-by-step guide on how to use vinegar and baking soda to get rid of mold and mildew smells in your camper:

Step 1: Identify the Source of the Odor

Before you start the cleaning process, it is important to identify the source of the mold or mildew smell. Check all areas of your camper, including the bathroom, kitchen, closets, windows, walls, doors, cabinets, floors, and roof. Look for any visible signs of mold, discoloration, or stains. Common areas for mold growth include windows, walls, doors, cabinets, and floors.

Step 2: Gather the Necessary Supplies

To clean mold with vinegar and baking soda, you will need the following supplies:

• Undiluted white vinegar
• Baking soda
• Spray bottle(s)
• Water
• Cleaning cloths or paper towels
• Protective gear (dishwashing gloves, protective goggles, and an N-95 or equivalent mask)
• Vacuum cleaner (optional)

Step 3: Prepare the Vinegar and Baking Soda Solutions

You can prepare two separate solutions of vinegar and baking soda, or you can mix them together to create a fizzing reaction. Here are the steps for both methods:

Method 1: Using Separate Solutions

• Fill one spray bottle with undiluted white vinegar.
• In a separate spray bottle, mix one-quarter tablespoon of baking soda with one cup of water. Shake the bottle to combine the mixture.

Method 2: Combining Vinegar and Baking Soda

• Add eight tablespoons (120 grams) of baking soda to a large mixing bowl.
• Pour in four tablespoons (60 milliliters) of white vinegar and allow the mixture to foam up.
• Stir the mixture together into a thick, gritty paste.

Step 4: Apply the Solutions to the Affected Areas

Once you have prepared your solutions, it's time to apply them to the affected areas in your camper. Here are the steps for both methods:

Method 1: Using Separate Solutions

• Spray the vinegar directly onto the moldy surfaces. Allow it to sit for about an hour.
• After the vinegar has dried, spray the baking soda solution onto the pre-treated areas. Ensure that you dampen the entire surface.
• Wipe off the baking soda spray with clean, damp cloths or paper towels.

Method 2: Combining Vinegar and Baking Soda

• Smear the vinegar and baking soda paste onto the moldy surfaces.
• Let the paste dry on the mold for about an hour.
• Wear protective gear, including dishwashing gloves, protective goggles, and a mask, during this process.
• Once the paste is dry, scrub it with a scouring pad or stiff brush to remove the mold and paste.
• Vacuum or bag up the removed mold and dispose of it immediately.

Step 5: Prevent Mold Regrowth

To prevent mold from regrowing in your camper, follow these tips:

• Dry out your camper thoroughly by opening windows and doors, and using a dehumidifier to remove excess moisture.
• Repair any leaks or sources of moisture, and improve ventilation in your camper.
• Regularly clean your camper, paying special attention to areas prone to moisture, such as windows, walls, and floors.
• Use moisture absorbers, such as silica gel packets or activated charcoal, to help absorb excess moisture in the air.
• Consider using commercial mold remediation products or a dehumidifier to prevent mold regrowth.

Increase ventilation

To get rid of a musty smell in your camper, you should increase ventilation. Open windows and roof vents to improve air circulation inside the camper. You can also use fans to keep the air moving and prevent moisture from settling. If your camper has been closed for an extended period, the air inside can become stagnant, allowing odors to accumulate.

If your camper has been in storage, open the windows and vents if possible. If you are camping, use ceiling vents or fans to promote air circulation and reduce moisture buildup.

Dehumidifiers or moisture absorbers can also help to reduce humidity levels and prevent mold and mildew growth. Desiccant dehumidifiers, for example, use specialized crystals to remove moisture without electricity. If your storage spot has electricity, you can run a small plug-in dehumidifier continuously while your RV is in storage.

Another way to increase ventilation is to run a range fan when cooking to remove excess moisture and heat.
