• VENTILATION! Air circulation is the key when it comes to preventing mold in your trailer. Open all windows, doors and vents to ventilate as much as possible. Even if you are using furnace, keep your roof vents at least halfway open.
  • Fix any water leaks in pipes, roof leaks, and damaged caulking.
  • Check if you have any air leaks and fix them.
  • Keep all surfaces dry and clean.
  • When cooking, washing dishes and taking shower, make sure to use vent fan and open window whenever possible.
  • Cover pots and pans when cooking.
  • Do not dry your clothes inside your trailer, especially towels and swimming suits.
  • Avoid carpets or consider removing your existing carpeting.
  • I HIGHLY suggest that you use a dehumidifier to remove all the excess moisture. This Ivation DehumMini Dehumidifier from Amazon is powerful and quite at the same time and will work great for RV- it is great for spaces up to 1,100 cubic feet.
  • Keep the humidity levels between 30 and 50 %. Use indoors humidity monitor to control the humidity.
  • DampRid Hanging Moisture Absorber is great to eliminate excess moisture in small spaces such as RV bathrooms, closets, storage compartments etc. It will not only collect all the excess moisture, but will also help against musty odors and keep the air fresh. It is especially useful when you are storing your travel camper away. It lasts up to 60 days. Just hang it and replace when the water bag is full. Great product to prevent unwanted mold and mildew.
