In this article, we will answer the following question: How do I get black spots off my RV? We will explain how to get rid of black spots on your Rv once and for all, what are the best products to do and the next steps after cleaning the RV.
How do I get black spots off my RV?
Getting black spots off your RV is easy and it requires just a few ingredients and lots of patience. The black spots on your RV are nothing else but mould and mildew.
Mould in an RV can be the result of roof leaks that went unnoticed. Mildew – a type of mould that thrives best in heat and humidity – is easy to remove, but stains left can be stubborn. Proprietary household mould cleaners can bleach the colour of the fabric, so particular care must be taken when using the proper chemicals.
Things you will need to get black spots off your RV:
- Raise the extending section of a pop-up camper to a place where it can dry completely. Once the fabric has dried, brush vigorously with a clean, dry brush to remove as much mould as possible.
- Soak a sponge in water, wring it out and pour in alcohol, then wipe the cloth with the sponge to remove surface mildew.
- Use your stiff brush, this time soaked in an alcohol/water solution rubbing one part alcohol to nine parts water. Be very careful not to put so much unsupported stress on the canvas that you tear. It has an associated bracket inside the pop-up caravan, glueing the area you are working with by holding a flat piece of cardboard that can be pressed against
- Rinse the fabric thoroughly after scrubbing. It may be necessary to scrub then rinse sections of the top one pop-up at a time because the rubbing alcohol/water solution should not be allowed to dry again on the canvas. Use a garden hose for this process, not a pressure washer, pressure washers, because they can damage the fabric or stitching.
- Use a bleach solution to remove mildew and hard stains from interior and exterior surfaces. Dilute the bleach according to the instructions on the bottle and wipe the entire surface with a clean cloth.
Note: Wear suitable protective clothing, including goggles while cleaning mould from your RV.
How to remove black spots from the interior walls of your RV
If you are concerned about the musty smell and fungus on the walls, the first thing to do is remove the black or green stains from the wall, cleaning the area well. Try some of these effective techniques to do it:
- Lavandin: it is one of the best disinfectants.
- Sodium bicarbonate: makes the smell of humidity and confinement disappear.
- White vinegar: used to eliminate all types of mould.
- Hydrogen peroxide: it is very effective and also has disinfectant properties.
Mould and fungi are formed mainly by three factors: the humidity produced by those who inhabit the house, the poor ventilation of the environments and the water leaks (in general, from the pipes that go inside the walls).
The first factor refers to all those actions of our day to day in which we produce humidity inside our houses: bathing, cooking or simply breathing. When combined with poor ventilation of the environments, the second key factor for the formation of mould, the place becomes more prosperous for this organism to emerge.
The third factor that helps mould growth is water leaks. These produce even more humidity in the environment, very conducive to the formation of fungi and mould.
The best products to remove moisture and fungus off your RV
As we said before, there are several products and alternatives to remove moisture from the walls, that is: to clean mold. Let’s delve a little more into its ways of use.
- Lavandin: It is one of the most effective disinfectant and fungicidal agents. The good thing is that it is very easy to get it in any supermarket or online store. It is a very strong and corrosive product, so we recommend you to be careful when using it, with rubber gloves and always keeping the bleach out of the reach of children.
To use it properly, make a solution by mixing one part water with one-fourth bleach and pour it into a sprayer. Spray the area affected by mould and wait a few minutes for the wall to whiten. Then use a brush or sponge to clean the area and rinse with plenty of clean water. If necessary, repeat this procedure until the walls return to their original colour.
- Baking soda: Although it is a product that has many uses (for cooking, for canker sores or making toothpaste and natural deodorant), you may not know how useful it is when it comes to fighting mould stains.
Prepare a solution with a tablespoon of baking soda for half a litre of water in a bottle or diffuser. Beat it well until it is diluted. Then, apply the solution to the affected area and, with a sponge, rub. This process repeated until all kinds of fungi were eliminated.
- White vinegar: White vinegar or apple cider vinegar are two good allies that will not require a lot of preparation to use them. Just fill a sprayer with either of these two types of vinegar and spray the mouldy area. Let it work for at least an hour and then rinse it off with clean water.
The only downside is that you will have to wait for the vinegar smell to wear off as the wall dries. I opened the windows, curtains and doors. Let the light and the air run.
- Hydrogen peroxide: The preparation of hydrogen peroxide to eliminate mould is very similar to that of vinegar. Fill a spray bottle with hydrogen peroxide and spray it over the fungal area. Let it work for 10 minutes. Then scrub with a sponge and rinse with clean water. Finally, you have to wipe the area with a dry cloth to permanently eradicate the mould.
What to do after you got black sport off your RV
The next step to cleaning the mouldy area with any of the above methods is to repaint the affected wall. There are different types of paints for damp walls:
Interior anti-humidity paint: it usually comes in different colours so that you can choose the one that best suits your wall. Its function is twofold: it is antifungal and waterproofing. This means that it not only eliminates but also prevents the formation of mould.
Paint for antifungal bathrooms: for the bathroom and kitchen you can use the type of paint nicknamed “latex”. It can be mixed with a common paint to later coat the walls of the bathroom or kitchen. It is a very good option if you did not find the colour you wanted within the options of anti-humidity paints.
Some final (and useful) tips that we can give you to prevent fungus and mould inside your RV is that you always keep it illuminated (with sunlight) and ventilated.
Also, whenever cooking or after showering in your RV, make sure you open a window or two, and that you always properly clean and maintain your motorhome.
