How to find mold in your RV and what to do about it

How do you know if you have mold in your RV? You can detect mold both by smell and by sight. Once you become familiar with what mold smells like – and if your sniffer is functioning – you can follow your nose to find mold. Oftentimes, it is hard to see as it may be hidden under carpets, flooring, or hidden away in lockers where water pipes are found. 

A mold test kit is another way to tell if there is something growing in the coach. There are a number of brands available and are available at

If mold is found, there are steps which can be taken to remediate the infestation. First and foremost is to find the source of moisture and stop it. In humid tropical climates, mildew and mold are commonplace, and you don’t even have to have a leak to get it. Most of us, however, usually find the fungus growing where there has been some sort of leak. Once the leak is stopped, the area has to be dried and cleaned. If the leak involves the inside of a wall or concealed space, it has to be opened up to air dry or the mold and rot will continue.

Amazon has a number of products and resources for mold remediation, and you can look them over here. Note that a hypochlorite solution (e.g., Clorox bleach) works very well, but can damage certain surfaces and materials, so be careful if you plan to use it.

    The only time I detect mold is when the prinary AC in my fifth wheel first cycles on. After a minute or two, the mold smell is not noticeable.

    Any suggestions as to why this is happening and what corrective action should I take?
