Mildew and Humidity Guide for Florida Boats, RVs and Aircraft

Humidity is the biggest year-round challenge for anything with a closed interior in South Florida. This guide explains why mildew happens and how to keep it away from your boat, RV or aircraft.

Why Florida is so humid on the inside

Warm, moist air gets into closed cabins and settles on soft surfaces like cushions, carpet and canvas. Without airflow it stays there, and mildew follows.

Boats and yachts

Check behind cushions, in lockers and along window tracks. Ventilate when it is safe, use moisture absorbers and wipe up condensation.

RVs

Run the air conditioning, open vents when you can and keep bathrooms and kitchens dry. Use moisture absorbers in cabinets and storage areas.

Aircraft

Air out the cabin when possible, wipe up moisture and keep the interior clean. Follow your manufacturer’s guidance for any moisture products.

Habits that help

Cleaning small mildew spots

Clean light mildew early with a product suited to the surface, and let the area dry completely. Test first and follow the label. Never mix cleaning chemicals.

When to look for the source

If mildew keeps returning, a leak or ventilation problem may be the cause. Cleaning removes the symptom, so have the source checked by a marine, RV or aircraft professional.

Frequently asked questions

Why does my boat cabin smell musty?

Moisture and little airflow let mildew grow on soft surfaces. Ventilate, dry and clean the area.

Does cleaning remove mildew?

Cleaning removes surface mildew. If it returns, look for the moisture source.

Can you clean mildew in my RV or boat?

We clean surfaces affected by mildew. We do not do repairs, so persistent leaks need a specialist.
