From roughly June through September, Central Florida gets an afternoon storm most days, followed by sun hot enough to dry the car in minutes. That cycle — wet, bake, wet, bake — is harder on a vehicle than a single dry season.
What the rainy season does
- Water spots, every day. Rain picks up airborne dust and pollutants; the droplets dry in the sun and leave mineral and contaminant rings on every horizontal panel.
- Reduced visibility. Oily road film on glass smears in rain; worn wiper edges chatter.
- Humidity in the cabin. Wet floor mats, damp seats and closed cars create mildew in carpet, headliners and door seals within days.
- Mold on soft tops and trim. Convertible tops and rubber seals under tree canopy grow mildew quickly.
- Mud and fertilizer runoff on the underbody and wheel wells from flooded roads and lawns.
Preparing for it
- Protect the paint before June. A sealant or ceramic coating makes rain sheet off and spots release with a gentle wash instead of etching.
- Treat the glass. A windshield rain repellent sheets water at speed and keeps film from building.
- Deep clean the interior. A steam and extraction interior detail removes the existing moisture and biology that mildew feeds on.
- Seal the soft top. Fabric and vinyl tops cleaned and re-proofed hold up through the season.
Maintaining through it
- Wash more often, not less. Rain is not a wash; it adds contamination. A deionized-water hand wash every week or two removes it.
- Dry the interior. Pull wet mats, crack windows in a garage, and address any damp smell immediately — it will not resolve on its own.
- Rinse the underbody after driving through standing water.
The membership argument
The rainy season is when a Weekly Wash Club or Signature Shine Plan earns its keep: the washes and interior maintenance happen on schedule, no matter what the sky did on Tuesday.
