Post-Trip Caravan Clean Down: The Essential Checklist

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

Don't let that red outback dust or coastal salt eat your investment. Here is exactly what you need to check, wash, and protect to keep your van in top nick.

Post-Trip Caravan Clean Down: The Essential Checklist

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 get back from a three-week stint at the Ningaloo or trekking through the Flinders and the last thing you want to do is scrub the van. But trust me, leaving that red dust to bake in the March sun is a recipe for disaster. I once saw a brand new Jayco ruined because the owner left bat droppings on the roof for a month in the heat, it ate straight through the finish. This checklist is the exact process I use in my shop to get vans back to showroom condition.

01

The Right Gear For The Job

What You'll Need

0/8
Long-handled wash brush — Get a soft-bristled one. Don't use those cheap ones from the servo that scratch the acrylic windows.
Heavy duty snow foam cannon — Essential for breaking down that sticky red dust before you touch the paint.
Bowden's Own Nanolicious Wash — My go-to because it's got great lubrication and deals with the Aussie sun well.
Dedicated Awning Cleaner — I reckon 303 Multi-Surface Cleaner is the best for getting mould off the vinyl.
Sturdy ladder with stand-offs — Don't lean it against the guttering unless you want a bent van (learned that the hard way).
Clay bar or mitt — For those stubborn bug splatters on the front nose cone.
Rubber seal conditioner — Keeps the window and door seals from cracking in the 40-degree heat.
Microfibre drying towels — Large ones. You've got a lot of surface area to cover before it water-spots.
02

Before You Turn On The Hose

What You'll Need

0/5
Close all windows and vents — Double check the roof hatches. The missus won't be happy if the bed gets soaked.
Check seals for perish — If they're cracked, go easy with the pressure washer or you'll flood the interior.
Remove loose fridge vents — Give them a separate clean to get the spiders and dust out of the mesh.
Inspect for stone chips — Mark them now so you can touch them up once it's dry.
Isolate 240v power — Safety first, mate. Unplug the shore power before spraying water everywhere.

The Cleaning Process

Tap each step to mark complete
01

The Underbody Blast

Get under there and blast the chassis and suspension. Focus on the nooks where salt and red mud hide. This is where the rust starts.

02

Pre-Soak and Foam

Lather the whole thing in foam. Let it dwell for 5 minutes (out of direct sun!) to lift the grime. Don't let it dry on the surface.

03

Roof Down Approach

Start on the roof. It's the dirtiest part and holds the most UV damage. Use your long brush and plenty of soapy water.

04

Contact Wash

Wash the sides using the two-bucket method. Work in sections. I always do the nose cone last because it's usually thick with smashed bugs.

05

Awning Scrub

Roll it out, spray your cleaner, and scrub gently. Rinse both sides thoroughly. Leave it out to dry completely before rolling it back up.

06

Solar Panel Wipe

Use a clean microfibre and plain water. Even a thin layer of dust drops your charging efficiency by 20% or more. (Truth be told, most people forget this).

04

Final Inspection

What You'll Need

0/4
Dry the acrylic windows — Do this first to prevent permanent water spotting. Use a very soft cloth.
Apply UV Protectant — I use Gtechniq C2 on the panels. It makes the next wash ten times easier.
Lube the stabiliser legs — A quick squirt of silicone spray keeps them moving smoothly for the next trip.
Check tyre pressures — While you're there, check for sidewall cracking from sun exposure.

Watch Out

Keep the pressure washer away from the decals and silicone joins. I've seen guys peel the graphics right off a brand new Trooper because they got too close. Also, never use dish soap, it strips the oils out of your seals and leaves the paint hammered.

Expert Tip

If you've been in the red dirt, that stuff gets everywhere. Give the door locks and padlock barrels a spray with a 'dry' graphite lube. Wet lubes just turn that dust into a grinding paste that'll jam your keys.
