Cleaning mildew from a fabric RV awning is different than cleaning mildew from an acrylic awning. Both offer a range of advantages and disadvantages. Vinyl RV awnings are typically crafted from premium marine quality vinyl while fabric RV awnings are usually acrylic fabric that is solution-dyed. The RV awning material type has a dramatic effect on how easy it is to remove mildew from the surface and if replacement will inevitably be required. Fabric awnings have a high tolerance for UV rays and tend to dry quickly. This can help prevent mildew before it has a chance to set it, but sometimes mildew is able to develop anyway. Removing mildew from fabric is a bit more difficult and in some cases, impossible. Vinyl awnings are mildew resistant, which makes it hard for mildew to develop, but it can happen when the surface is not cleaned properly or when there is too much humidity in the air. Removing mildew from vinyl takes a bit of elbow grease but in most cases, is easier to clean when compared to fabric.

You should clean your RV camper awning at least twice a year to prevent mold and to keep it looking its best. Sap, dirt stains, and water stains can easily leave your RV awning looking worn down, and improperly cared for awnings can develop mold or mildew if left unchecked. It is a good idea to do a light cleaning each time you clean the exterior of your RV. A gentle wash with your hose is often enough to clear away debris and dust that can encourage mildew growth on the top and underside of the awning.

Make sure to allow the awnings to dry completely before closing them to prevent mold and mildew from developing.

For those who use their RV full time or who travel often, a deep cleaning is required at least once every three months. This will allow you to catch stains, mold, mildew, or any other damage early on. Always use gentle detergent or a proper awning cleaner when caring for your camper. Pair the cleaner or detergent with a soft-bristled brush for the most effectiveness. 

Tips For Preventing Mildew From Forming on the Awning

Preventing mildew formation is the best way to ensure your RV awning will serve you and your family for years to come.

Dry Them Before Storage

The number one rule to prevent mildew on both fabric and vinyl RV awnings is to always make sure they are completely dry before they are stored. Improper or incomplete drying is the main cause of both mildew and mold on both sides of the awning surface.

Following a light rain shower or after your regular cleaning, make sure it is dry before rolling it up. This also applies to awnings that were used in humid environments.

Limit Exposure to UV Rays

When you are not using your RV awnings, make sure they are dry and then roll them up. Too many UV rays can weaken the material and cause the protective layer to wear down much quicker than normal. The protective layer not only helps keep your awning in good condition, but it also protects it from water damage. Anything that damages that layer can result in the development of mold or mildew.

Adjust Awning During Heavy Rains

Pay attention to the weather as well. An awning will protect you from the sun and rain, but when there is heavy rain, make sure the awning is positioned in a way that allows the water to run off. Pooling water in the center can cause excessive wear and tear in addition to encouraging mildew to develop.

Treat Your RV Awning

Treat your RV awning with protective sprays or rubs to help prevent mold and mildew damage. For fabric RV awnings Better Boat is a highly effective option.

For vinyl RV awnings, you can use Star Brite Vinyl Guard to keep mildew from damaging the surface.

Final Note on Protecting An RV Awning

RV awnings are an essential part of your vehicle that can make your leisure time much more comfortable. Proper maintenance will keep them in good working order so that you can enjoy the benefits of owning an awning for years to come. Make a point of cleaning your awning at least four times a year and treat any mold or mildew you find right away. With these tips, your awning can last for years to come.
