How to Clean Your Caravan and Get Rid of That Red Dust (Mar 2026)

Red dust, creek crossings, and corrugated roads don't just test your 4WD—they test your cleaning game. Most people get it wrong.

Cleaning a caravan isn't just about a quick hose down. Between the baked-on red dust from the interior and the salt spray from the coast, you need a solid plan to protect your investment before the weather turns.

How to Clean Your Caravan and Get Rid of That Red Dust (Mar 2026)

Aussie Conditions

Aussie red dust is iron-rich and bonds to paint. A regular rinse won't cut it—you need proper pre-wash and pH-neutral soap to avoid scratching.
Quick Summary

Look, we've all been there, you come back from a three-week stint up north and the van looks like it's been through a blender with a bag of Cheetos. This guide is for the weekend warriors and the grey nomads who want to keep their rig looking schmick without spending three days scrubbing. I'll show you how to tackle everything from those nasty black streaks to that stubborn red outback dust that gets into every single crevice.

01

Keeping the Home on Wheels Fresh

Right, so you've just got back from a cracker of a trip. Maybe you hit the Gibb River Road or just spent a fortnight down at the coast. Either way, your caravan is probably looking a bit worse for wear. I've been detailing for over 15 years now, and let me tell you, caravans are a different beast compared to cars. You've got aluminium, fibreglass, plastics, and heaps of sealant all living together, and they all react differently to the Aussie sun. I learned this the hard way when I used a harsh degreaser on a mate's older Jayco and it practically melted the window seals. Never again. Now that we're heading into Autumn, it's the perfect time to get the grime off before the UV really starts to bake it in. If you leave that red dust or bird muck sitting there over the cooler months, you're asking for permanent staining. Let's get stuck in.

What You'll Need in the Driveway

What You'll Need

0/9
A decent telescopic wash brush — Get one with soft bristles. If it feels like a broom, don't let it near your paint.
Two 20L buckets — One for soapy water, one for rinsing your mitt. The 'two-bucket method' is non-negotiable.
Quality pH-neutral wash — I reckon Bowden's Own Nanolicious is great, or Meguiar's Gold Class if you're on a budget.
Black streak remover — Specifically for those annoying vertical lines under the windows.
Microfibre wash mitt — For the lower sections where the brush can't get the fine grit.
A sturdy ladder — Make sure it's on level ground. I've seen more blokes end up in A&E than I care to count.
Pressure washer (optional) — Great for the chassis, but keep it away from the vents and seals.
Large microfibre drying towel — The Gyeon Silk Dryer is a ripper, saves you ages on a big van.
UV Protectant/Sealant — Something like Gtechniq C2V3 or a good marine-grade wax.

Before You Pick Up the Hose

Tap each step to mark complete
01

Check the seals

Give all your window and door seals a quick look. If they're cracked or peeling, high-pressure water will find a way inside and ruin your missus's favourite cushions.

02

Close everything up

Double-check the roof hatches, vents, and windows. I once started washing a customer's Winnebago only to realise the skylight was cracked open. Not a fun conversation to have.

03

Move it to the shade

If you try to wash a 20-foot van in the midday sun, the soap will dry before you've даже finished one side. Do it early morning or late arvo.

04

The Full Detail Procedure

Tap each step to mark complete
01

The Chassis Blast

Start from the bottom. If you've been on the beach, you need to get that salt off the frame. Use a high-pressure hose to get into the nooks of the suspension. Don't be shy here.

02

The Pre-Rinse

Rinse the whole van with just water. This knocks off the loose 'easy' dirt so you don't drag it across the paint later and cause scratches.

03

Snow Foam (If you've got it)

I love using a foam cannon for caravans. It dwells on the vertical surfaces and breaks down the red dust. Let it sit for 5 minutes, but don't let it dry.

04

Start with the Roof

Worst job first. Get up on that ladder and scrub the roof. It's usually covered in bat droppings and sap. If you leave the roof for last, all that filth will run down over your clean sides.

05

The Top-Down Scrub

Work in sections (maybe 2 metres at a time). Use your soft brush and plenty of soapy water. Don't press hard; let the soap do the heavy lifting.

06

Tackling Black Streaks

If you see those dark lines, spray a bit of dedicated streak remover on a microfibre cloth and wipe them away. Don't use a kitchen scourer, I saw a bloke do that once on a brand new Crusader and he ruined the gelcoat.

07

Window Care

Most caravan windows are acrylic, not glass. They scratch if you even look at them funny. Use a very clean microfibre and heaps of water. Avoid ammonia-based glass cleaners; they'll make the plastic go cloudy over time.

08

The Final Rinse

Give the whole thing a massive rinse. Make sure no soap is hiding behind the awning arms or in the fridge vents.

09

Drying

Use your big drying towel. If you leave it to air dry in Australia, you'll get nasty water spots from the minerals in our water. It's a pain, but worth the effort.

10

Wheels and Tyres

Give the rims a scrub and chuck some tyre shine on. It makes the whole rig look 10 times better, trust me.

Watch Out

Be bloody careful with the pressure washer around seals, decals, and vents. I've seen people blast their decals right off the side of the van, or worse, force water into the fridge vents which can short out the electronics. Keep the nozzle at least 30-50cm away from anything delicate.

Dealing with Red Dust

If you've got that fine red outback dust inside the cupboards, don't use a wet cloth first. It just turns into mud and stains everything. Use a vacuum with a soft brush attachment first to get 90% of it out, then follow up with a damp cloth. It saves so much heartache.

Protecting the Finish

Since caravans are huge, nobody wants to hand-wax them every month. I reckon a 'spray and rinse' sealant like Gtechniq W6 or even a simple ceramic spray coating is the way to go. You just spray it on the wet van after washing, rinse it off, and it leaves a layer of protection that lasts a few months.
05

Ongoing Maintenance

Once the van is clean, don't just park it under a gum tree and forget about it. If you aren't using a cover (which can actually scratch the paint if it's windy, to be honest), try to give it a quick rinse every few weeks. If a bird drops a 'present' on the roof, get it off immediately. Our Aussie sun is so hot it'll bake that acid into the paint in about two hours, leaving a permanent mark. Also, keep an eye on your solar panels. A layer of dust can drop their efficiency by 20% or more, which is the last thing you want when you're trying to keep the beers cold in the middle of nowhere.
06

Common Caravan Queries

Can I use dish soap to wash my caravan?
Look, people do it, but I wouldn't. Dish soap is designed to strip grease, which means it'll strip any wax or protection off your paint too. Stick to a proper car or boat wash.
How do I get rid of the yellowing on my fibreglass?
That's usually oxidation from the UV. You'll need a light cutting compound and a bit of elbow grease. If it's really bad, you might need a machine polisher, but be careful not to burn through the gelcoat.
The red dust is stuck in my awning, what do I do?
Open the awning fully, soak it with a mild soapy solution, and use a soft brush. Don't roll it back up while it's wet, or you'll have a mould problem next time you open it.
Is it worth ceramic coating a caravan?
If you've got a brand new van and the budget for it, absolutely. It makes washing so much easier because the dirt just doesn't stick. But if it's an older rig, a good quality sealant is probably enough.
