Comfortable and supportive RV mattresses can ensure you enjoy a good night's sleep while traveling solo or with family and friends. However, since these mattresses may be vulnerable to mold buildup, it's important that you know how to protect them. Here's how to keep your bedding clean and sanitary. 

What Causes Mold Growth on RV Mattresses?

Mold consists of fungal spores that reproduce in damp areas. When you sweat at night, your RV mattress may absorb this moisture, which can create a favorable environment for mold growth. Temperature differences between your body and the interior of the mattress may cause condensation to form and absorb into the material.

RV bed bases also typically consist of a plywood sheet that might not allow excess fluids to drain or dry. Additionally, if the inside of your RV becomes too humid, moisture may seep into your bedding. Any combination of these factors can increase the risk of fungal growth. 

Why Is Mold a Problem?

Mold typically emits musty or rancid odors that can quickly make spending time in your RV unpleasant. Additionally, inhaling airborne spores may cause allergenic rhinitis, asthmatic reactions, or lung infections

Spores that make contact with the skin can lead to rashes and infections. Fungal growth may also leave unsightly black or gray spots and streaks that diminish the appearance of your mattress and make your RV interior less aesthetically pleasing. 

How Can You Protect Your RV Mattresses From Mold?

You can prevent moisture from accumulating at the base of the bed by insulating the frame with cardboard or a foam topper. These materials can absorb sweat and condensation to keep your mattress dry and clean. 

However, since mold might eventually grow on the cardboard or topper, you'll need to replace these materials every couple of months. Alternatively, you can use a hard plastic underlay, which keeps a pocket of air between the mattress and the base of the bed, allowing moisture to dry and disperse. 

Rotating your RV mattress every few months can prevent moisture produced by sweat from accumulating in the same areas of the material and causing mold to develop. You can also prop up the mattress on its side and use a box fan or heater to dry any residual wetness.

Additionally, you should remove excess moisture from your RV and keep indoor humidity levels within the ideal range of 30-50% by using portable dehumidifiers in sleeping areas. Installing a new HVAC system that provides more effective ventilation and climate control can also reduce humidity.
