A major cause of mold and mildew is long term storage. Keeping a trailer or camper locked down or under a tarp, can create a very efficient mold and mildew incubator.
Even an RV that is used year round and never put into storage is not immune from mold and mildew. This is because full-time RVers tend to follow the sun to warmer climates which encourages endless mold and mildew growth – especially for those touring Florida and Texas.”
For RV owners these three steps can help keep the problem under control:
1) Inspect – Look for early signs of mold and mildew in places such as shower areas, underneath sinks and stoves, gel coat exteriors, storage compartments, caulking and molding (around windows, doors and sunroofs) ceilings, ceiling vents, vinyl awnings, water and sewerage hook-ups, and refrigerators, dishwashers and washing machines that have not been used for extended periods.
2) Repair – Fix plumbing leaks, drain clogs, roof leaks, damaged caulking or molding and poor bathroom ventilation that can encourage mold and mildew growth.
3) Remove – Treat emerging mold thoroughly with a multi-purpose stain/mildew remover.
