A caravan that spends its life in one climate is easy to plan for. A caravan in Western Australia is not. The temperature swings, the salt off the coast, the red dust inland and the damp of a Perth winter all stress different parts of the van at different times of year. That’s why a fixed monthly wash rarely covers everything. Building a seasonal rhythm keeps ahead of the damage, and while plenty of the work suits a home schedule, deeper restoration is where professional caravan detailing services in Perth fit into the yearly plan.
Here’s how to think about care across the four seasons, and how to turn it into a repeatable checklist by surface type.

Summer: UV, Heat and Oxidation
Summer is the harshest season for exterior surfaces. Long, intense UV exposure fades painted panels and slowly breaks down the gelcoat on fibreglass. Left unchecked, that shows up as a chalky, dull surface known as oxidation.
The main goal in summer is protection. Keep a fresh layer of wax or sealant on painted and fibreglass panels so UV hits the coating rather than the surface underneath. Wash in the early morning or late afternoon when panels are cool, because washing hot surfaces in direct sun leaves water spots and streaks that are hard to remove.
Check rubber seals and window gaskets too. Heat dries them out, and cracked seals let water in later in the year. A quick inspection now saves trouble in winter.
Salt Air All Year Round
Salt is not a seasonal problem in WA, it’s a constant one for anyone living near the coast or touring the beaches from Perth up north. Salt-laden air settles on the van, draws moisture and accelerates corrosion on aluminium trim, fasteners and any exposed metal.
If your van lives near the coast or has just come back from a coastal trip, rinse it thoroughly with fresh water. Pay attention to the underbody, wheel arches and any joins where salt collects. Regular rinsing is the single most effective habit for coastal owners, regardless of the month.
Autumn: Dust, Grime and Post-Trip Decontamination
Autumn is prime touring season in WA, and that means red dust. It works into every seam, vent and awning channel. Dust is abrasive, so wiping it off a dry panel can leave fine scratches.
After a trip, follow a proper decontamination routine rather than a quick hose-down:
- Pre-rinse to lift loose dust before you touch the paint.
- Wash top to bottom with a dedicated caravan or vehicle wash, using two buckets to keep grit out of your wash mitt.
- Clear dust from awning rails, window tracks and roof channels where it hides.
- Inspect and clean seals so grit doesn’t grind into them.
This is also the ideal window to reassess protective coatings before the wetter months arrive.
Winter: Damp, Mould and Roof Care
Perth winters are cooler and wetter, and the risk shifts from UV to moisture. Standing water, poor drainage and condensation create ideal conditions for mould, both inside and on external surfaces.
The roof deserves the most attention in winter. It takes the brunt of the rain, and its membrane or sealed joins are what keep water out. Clear debris, check that seams and sealant are intact, and make sure water drains rather than pools. Inside, keep the van ventilated on dry days to reduce condensation and the musty smell that comes with it.
Watch shaded, low-airflow spots like the bottom of walls and around seals, where mould takes hold first.
A Seasonal Checklist by Surface Type
Rather than remembering every task by month, it helps to organise care by surface. Each one has a different weak point:
- Roof: Check seals and membrane before winter, clear debris and dust year-round, and inspect after any hail or storm.
- Aluminium panels and trim: Rinse salt and dust regularly, watch for corrosion at joins and fasteners, especially near the coast.
- Fibreglass: Keep protection topped up through summer to slow oxidation, and wash gently to avoid scratching the gelcoat.
- Painted panels: Maintain wax or sealant against UV, wash cool, and decontaminate after dusty trips.
Rotating through these each season means nothing gets overlooked for long.
When to Call in Professional Help
A home wash handles routine dust, salt rinsing and general upkeep. Some jobs, though, sit beyond a driveway routine. If the paint or gelcoat already looks dull and chalky, if oxidation has set in, or if you want a durable protective coating applied properly before summer, that’s specialist work. The same goes for stubborn mould, roof sealing concerns or a full post-season decontamination.
A good approach is to keep up the weekly and seasonal basics yourself, then schedule deeper detailing once or twice a year, timed to the seasons that hit hardest.
Following this calendar keeps your van in good shape while it’s on the road. But every seasonal plan includes stretches where the caravan simply sits, sometimes for weeks or months between trips. Preparing a van the right way before it goes idle for an extended period is a discipline all its own, and it’s worth understanding well before you park it up for the long haul.
