Keeping Your Caravan Mint After a Big Trip

Your paint is under constant attack: UV rays, bird droppings, tree sap, and road grime. Protection isn't optional—it's essential.

Don't let red dust and salt spray eat your investment. Here is how to clean your van properly without ruining the seals or scratching the finish.

Aussie Conditions

Our intense UV breaks down waxes faster than overseas. Ceramic coatings last longer, but even they need topped up more frequently here.
Quick Summary

Look, we've all been there, you get back from a three-week stint up the coast or out in the red dirt and the van looks like it's been through a war zone. If you leave that grime sitting there, the Aussie sun will bake it into the gelcoat faster than you can crack a cold one. This is a quick rundown on how to get it sorted properly so it actually lasts.

01

The Post-Trip Reality Check

Most blokes make the mistake of leaving the van sitting in the driveway for a month after a trip. Big mistake. Between the bird droppings that eat through paint and that fine red dust that finds its way into every seal, you're asking for trouble. I once had a customer bring in a top-of-the-line Jayco that had sat under a gum tree for six months. The sap had literally fused to the roof. Saved it eventually, but it cost him a fortune in paint correction. Get onto it early and use the right gear.

The 'Snow Foam' Secret

Don't just start scrubbing with a sponge. You'll drag red dust across the surface and scratch the hell out of it. I reckon a good snow foam is mandatory for vans. Chuck some Bowden's Own Snow Job in a cannon and let it dwell for 5-10 minutes (not in direct sun, obviously). It lifts the grit off the surface so you can pressure wash it away safely. Honestly, I wouldn't bother washing a dirty camper without it.

Watch Those Seals

When you're using the pressure washer, don't get too close to the window seals or the fridge vents. I learned this the hard way when I accidentally flooded a mate's camper electrics by being too gung-ho with a 3000 PSI washer. Keep back at least a metre and use a wide fan spray. You just want to rinse, not blast the rubber off.

Kill the Salt

If you've been beach camping or even just driving along the Great Ocean Road, salt is your enemy. Use a dedicated salt neutralizer like Salt-Away or the Aussie-made Salt-Off. Spray it everywhere, especially the chassis and the suspension components. Standard soap won't always neutralise the salt, and it'll start rusting your leaf springs before you know it.

Protect the Gelcoat

Caravans are mostly fibreglass/gelcoat, which is way more porous than car paint. After it's clean, you need a sealant. I'm a big fan of Gtechniq Easy Coat or even Meguiar's Hybrid Ceramic Wax. You just spray it on while the van is wet and rinse it off. It adds a layer of UV protection that stops the white panels from turning chalky and yellow in the 40-degree heat.

The Bare Essentials

What You'll Need

0/5
Long-handle soft wash brush — Get one with flagged bristles so it doesn't scratch the acrylic windows.
Microfibre wash mitt — Better than a sponge for trapping dirt away from the surface.
pH Neutral Car Wash — Avoid dish soap! It strips the oils out of your seals and makes them crack.
Dedicated Bug Remover — Essential for the front nose cone where the grasshoppers have baked on.
Ladder with stand-off — To get to the roof without leaning against the delicate tin or composite panels.

Watch Out

Never use a 'truck wash' (the heavy-duty degreaser stuff) on a caravan with decals or silicon seals. Most of that gear is caustic. It'll make your paint look great for ten minutes, then it'll dry out your seals and fade your expensive vinyl wraps. Also, don't walk on the roof unless you're 100% sure where the structural supports are. I've seen more than one bloke put a foot through a skylight.
03

Common Questions

How do I get red dust out of the awning?
Give it a good soak with a mild soap and a soft brush, then let it dry completely before rolling it up. If you roll it wet, you'll get mould, and that's a whole different nightmare to fix.
What's the best way to clean acrylic windows?
Never use Windex or ammonia-based cleaners. They'll craze the plastic. Use plenty of water and a very clean microfibre cloth. If they're already scratched, a light plastic polish like Novus works wonders.
Should I wax the roof?
If you've got the energy, go for it. But honestly, a spray-on ceramic sealant is much easier for a big surface and does a better job at reflecting those harsh UV rays.
04

Wrap Up

At the end of the day, a clean van is a happy van. Give it a good crack as soon as you get home, and it'll stay looking new for years. Anyway, the missus is calling for lunch, so I'm off. Good luck with the scrub!
