Keeping Your Caravan or Camper Looking Brand New (Mar 2026)

Aussie Conditions

Australian conditions are tougher than most—intense UV, red dust, coastal salt, and 40°C summers. European car care advice often doesn't cut it here.
Quick Summary

Look, I've spent 15 years cleaning everything from daily drivers to $200k off-road caravans, and let me tell you, a camper is a different beast entirely. This guide walks you through the exact process I use in my shop to get rid of that stubborn red dust, bird lime, and road grime. Whether you've just come back from the Gibb River Road or a weekend at the coast, I've got you covered with the right gear and techniques for Australian conditions.

01

The Reality of Keeping a Rig Clean Down Under

Right, let's have a chat about caravans. Most people buy their dream rig, spend a fortune on it, and then realize after the first trip to the Red Centre that the dust doesn't just 'wash off'. I learned this the hard way years ago when I tried to use a standard car soap on a mate's fiberglass camper that had been sitting under a gum tree for six months. I spent four hours scrubbing and barely made a dent. Truth is, between the UV levels we get in March and the sheer surface area of these things, you need a proper game plan. After 15 years in the trade, I've seen it all. I’ve seen brand new Jaycos with 'chalky' fiberglass because the owner used dish soap (don't ever do that, seriously), and I've seen aluminium cladding pitted by salt spray because it wasn't rinsed properly after a beach run. The Australian sun is brutal. If you aren't protecting your gelcoat or paint, it’s going to oxidize and look like rubbish within two seasons. Thing is, cleaning a caravan isn't just about making it look pretty for the next site. It's about maintenance. Those seals around your windows and roof hatches? If they're caked in grit and bird droppings, they're going to fail. And we all know that a leak in a caravan is the start of a very expensive nightmare. So, whether you've got a massive 24-foot tandem axle or a little forward-fold camper, the principles remain the same. You need the right chemicals, a bit of elbow grease, and the patience to do it right. I reckon if you follow this guide, you'll not only save yourself a few grand in depreciation but you'll also be the envy of the caravan park. Let's get stuck in.

The Gear You Actually Need

What You'll Need

0/13
A Proper Extendable Wash Pole — Don't buy the cheap $15 ones from the budget shops; the heads flip around and scratch your panels. Get a sturdy one with a soft-bristle head designed for vehicles.
Two 20L Buckets with Grit Guards — One for your soapy water, one for rinsing your brush/mitt. This is non-negotiable if you want to avoid swirl marks.
Dedicated Caravan Wash (pH Neutral) — My go-to is Bowden's Own Nanolicious or Meguiar's Gold Class. Avoid anything with high acidity unless you're stripping old wax.
Snow Foam Cannon — If you have a pressure washer, this is a lifesaver for getting into the nooks and crannies of the awning and window seals.
Degreaser or All-Purpose Cleaner (APC) — Essential for the drawbar, jockey wheel, and suspension components, especially after an off-road trip.
Bug and Tar Remover — The front of your van will be a graveyard for Aussie insects. You need something that breaks down the proteins without killing the shine.
Non-Acidic Wheel Cleaner — Caravan wheels get neglected, but brake dust can eat into the finish over time.
Rubber and Trim Dressing — To keep your window seals from cracking in the 40-degree heat.
Large Microfiber Drying Towels — I use the 'Big Green Sucker' or similar. You'll need about three for a full-sized van.
Soft Detailing Brushes — For cleaning around vents, door handles, and those pesky awning arms.
Clay Bar or Clay Mitt — For when the surface feels 'crunchy' even after washing, usually from fallout or sap.
UV Protective Sealant — Gtechniq or a high-quality ceramic spray sealant. This is your shield against the sun.
A Sturdy Ladder — Safety first. Make sure it's got rubber feet so it doesn't slip on wet concrete.

Pro Tip: The Reach Test

Before you start, check if you can actually reach the middle of the roof. Most people forget this and end up with a 'mohawk' of dirt right down the center of the van that they can't reach from the ladder. If your brush doesn't reach, you might need to carefully (and I mean carefully) get up on the roof, but only if it's rated for it!

Preparation: Setting Yourself Up for Success

Tap each step to mark complete
01

Park in the Shade

I cannot stress this enough. If you wash a caravan in the direct Aussie sun, the soap will dry before you can rinse it, leaving nasty streaks that are a nightmare to remove. If you don't have a big enough shed, do it early in the morning or late arvo.

02

Close Everything Up

Check every window, roof hatch, and door. Double-check the seals. A customer once forgot to close their bathroom hatch, and I ended up pressure washing the inside of their shower. Not my best day.

03

Disconnect Power

Unplug the 15A lead. Water and electricity don't mix, and you don't want to accidentally soak your inlet socket while it's live.

04

Pre-Rinse the Underbody

Before you clean the shiny bits, get under there with a hose. Get rid of the mud and salt from the chassis and suspension so you don't splash it back up later.

05

Set Up Your Two-Bucket System

Fill one with clean water and one with your soapy solution. Chuck your wash mitts and brushes in to soak.

How to Clean and Protect Your Caravan After a Big Trip (Mar 2026)

Watch Out

Be bloody careful with pressure washers around caravan decals and seals. If you get too close, you'll peel the stickers right off or blast water past the window seals into the wall cavity. Keep the nozzle at least 30-50cm away from anything delicate.
04

The Step-by-Step Deep Clean

Tap each step to mark complete
01

The Big Rinse

Start from the top. Use a hose to knock off all the loose grit. This is critical, if you start scrubbing while there's loose sand on the surface, you're basically using sandpaper on your paint.

02

Clean the Roof First

Always start high. If you do the sides first, all the filth from the roof will just run down and ruin your work. Scrub the solar panels gently, they lose efficiency if they're caked in dust.

03

Apply Bug Remover

Spray your bug remover on the front nose cone. Let it dwell for 3-5 minutes, but don't let it dry. Use a soft sponge to wipe away the bug guts.

04

Snow Foam (Optional but Recommended)

Coat the whole van in foam. Let it sit and pull the dirt down. This is the best way to get red dust out of those annoying aluminium 'checker plate' sections.

05

The Contact Wash

Work in sections, roughly 2 meters wide. Use your wash pole or mitt, starting from the top and moving down. Rinse your tool in the 'clean water' bucket frequently.

06

Focus on the Awning

Wind the awning out a bit. Clean the vinyl with soapy water and a soft brush. Don't roll it back up until it's 100% dry, or you'll get mold, and trust me, that's a whole different headache.

07

Clean the Windows

Most caravan windows are acrylic, not glass. They scratch if you even look at them wrong. Use a very soft microfiber and plenty of lubrication (soap). Never use Windex or ammonia-based cleaners; they'll cloud the plastic.

08

Wheel and Tyre Scrub

Use your wheel cleaner and a stiff brush for the tyres. Get into the arches, that's where the salt hides after a coastal trip.

09

Final Rinse

A thorough rinse from top to bottom. Pay attention to the 'gutters' and window tracks where soap suds like to hide.

10

The Drying Phase

Use your large microfiber towels. If you leave it to 'drip dry' in Australia, you'll get water spots from the minerals in our water. Pat it dry, don't just drag the towel.

11

Decontamination (If needed)

If the paint still feels rough, use a clay mitt with plenty of soapy water as lube. This pulls out the embedded iron filings and sap.

12

Sealant Application

Apply your ceramic spray or wax. This is your UV shield. I reckon a good spray sealant like Bowden's Bead Machine is brilliant for vans because it's fast to apply over such a large area.

13

Dress the Seals

Apply a rubber protectant to all window and door seals. This keeps them 'squishy' so they actually seal.

14

Tyre Shine

Last step, chuck some dressing on the tyres. It doesn't just look good; it helps prevent sidewall cracking from UV exposure.

05

Dealing with the Dreaded Red Dust

Look, if you've just come back from the Oodnadatta Track, standard soap won't cut it. Red dust is oily and acidic. I've found that using a pre-wash like an alkaline foam (something like Bilt Hamber Auto-Foam) helps break that static bond it has with the paint. If it's really stuck in the checker plate, you might need a soft-bristled toothbrush and some serious patience. I once spent six hours just on the drawbar of a Bruder trailer because the red dust had basically baked onto the powder coat. Don't rush it, or you'll just swirl the paint.

Pro Tip: The 'Two-Person' Awning Trick

When cleaning the top of the awning, have someone slowly wind it in while you stand on the ladder with a wet microfiber. It cleans the vinyl much more evenly than trying to reach across the whole thing while it's fully extended.
06

Advanced Techniques: Restoring Faded Gelcoat

If your van has gone 'chalky' or matte, a simple wash won't fix it. This is oxidation. You'll need a dual-action (DA) polisher and a medium-cut compound. Gelcoat is much thicker and harder than car paint, so you can be a bit more aggressive, but you still need to be careful around corners. I usually use a wool pad on a rotary for heavy oxidation, but if you're doing it yourself, stick to a DA polisher to avoid burning the finish. Once you've got the shine back, you MUST seal it immediately. Polished gelcoat is porous, and if you don't seal it, it'll oxidize again in about three months under the Aussie sun. I'd go for a dedicated marine-grade ceramic coating if you want it to last.
07

What Works and What's a Waste of Money

I've tried every 'miracle' caravan cleaner on the market. Honestly? Most of the 'waterless' washes are rubbish for anything more than a light dust. They'll scratch your van if there's any real dirt on it. For soap, I'm a big fan of Aussie-made Bowden's Own. Their 'Snow Job' foam is great. For protection, I've moved away from traditional waxes, they just melt in 40-degree heat. Use a polymer sealant or a ceramic spray. Gtechniq C2V3 is a cracker for this, it's easy to use and lasts months. Avoid 'Truck Wash' unless your van is extremely dirty and you plan on re-waxing it immediately, as most truck washes are high-pH and will strip every bit of protection off the surface.
08

Aftercare and Long-Term Maintenance

Once she's clean, the job isn't quite finished. If you're storing the van outside, invest in a high-quality, breathable cover. Don't just use a cheap blue tarp from the hardware store; they trap moisture and the wind will make the tarp flap against your paint, scratching it to bits. Every couple of months, give the van a quick 'maintenance wash' with a wax-safe shampoo. This stops the dirt from building up and making the next big clean a nightmare. Also, keep an eye on your roof sealants. Every time you're up there cleaning, check for cracks in the Dicor or Sikaflex around the vents. Catching a crack early saves you five figures in water damage repairs down the line. I reckon a bit of preventative maintenance is the difference between a van that lasts 5 years and one that lasts 25. And yeah, that's pretty much it, keep it clean, keep it sealed, and it'll look after you.
09

Common Questions from the Campground

Can I use dish soap to wash my caravan?
No way. Dish soap is designed to strip grease from pans, which means it'll strip the wax and oils right out of your paint and gelcoat. It'll leave your finish 'dry' and prone to oxidation.
How do I get black streaks off the sides?
Those are usually caused by the rubber seals on the roof or windows breaking down. Use a dedicated 'Black Streak Remover' or a gentle APC. To stop them coming back, keep your roof clean and your seals dressed.
Is it safe to walk on the roof?
Check your manual! Most modern 'sandwich panel' roofs are okay if you stay on the internal cross-members or use a piece of plywood to spread your weight. If in doubt, stay on the ladder.
How often should I wax my caravan?
In Australia, I'd say every 3 to 4 months if it's stored outside. If you use a ceramic sealer, you can get 6-12 months out of it.
What's the best way to clean solar panels?
Just plain water and a very soft brush. Don't use harsh chemicals or abrasive pads, as you'll scratch the glass and reduce the power output.
Can I use a car polish on my aluminium cladding?
If it's painted aluminium (like most modern vans), yes. If it's raw 'mill finish' aluminium, you'll need a metal polish like Autosol, but be prepared for a huge job.
