What You'll Learn
Aussie Conditions
Look, we've all been there. You come back from a weekend up the coast or a run through the Victorian High Country and your rig is absolutely caked. This guide is for anyone who actually uses their 4x4 or daily driver and wants to keep it looking decent. I'm going to walk you through the exact process I use in my shop to tackle heavy mud and that nightmare red dust that seems to get into every single crevice.
The Reality of Aussie Mud
The Gear You'll Actually Need
What You'll Need
While you're here...
Before You Get Started
Park in the shade
Never, ever wash a muddy car in direct 2pm sun. The heat makes the mud go rock hard and your soap will dry in seconds, leaving nasty spots. If you haven't got a carport, wait until the arvo when it cools down.
Cool down the panels
Give the car a quick spray with just the hose to bring the surface temp down. If you've just come off the highway, don't spray cold water directly onto hot brake rotors or you'll warp them. (I've seen it happen on a brand new Hilux, not a cheap fix!)
Set up your buckets
Fill one with your soapy water and the other with plain water. This 'two-bucket method' is the only way to ensure you aren't putting dirt back onto the car.
The Step-by-Step Clean
Underbody First
Get down low and blast the mud out from the chassis rails and wheel arches. If you've been in red dust or salt, this is the most important bit. Use a dedicated underbody tool if you've got one, otherwise just get in there with the wand.
The Initial Rinse
Use the pressure washer to knock off the heavy chunks. Start from the top and work down. Don't get the nozzle too close to the paint, keep it about 30cm back so you don't blast the paint right off a plastic bumper.
Snow Foam Soak
This is the game changer. Cover the whole car in a thick layer of foam. This dwells on the surface and pulls the dirt away from the paint. Let it sit for 5-8 minutes, but don't let it dry!
The Detail Brush Work
While the foam is sitting, take a soft brush and go around the badges, fuel cap, and window seals. This gets the red dust that a mitt can't reach.
Power Rinse
Blast all that foam off. You'll see a heap of brown sludge coming off with it. Most of the grit should be gone now.
The Contact Wash
Now you actually touch the car. Dip your mitt in the soap, wash a panel, then rinse the mitt in the plain water bucket before getting more soap. Work from the roof down to the sills.
Wheel and Tyre Scrub
Use a degreaser on the tyres and a brush on the rims. A customer once brought in a Ranger with 'stained' wheels, it wasn't stained, just three months of baked-on brake dust and mud. A bit of elbow grease and APC sorted it.
The Final Flood
Take the nozzle off the hose and let the water just flow over the car. This 'sheeting' method helps the water run off, making drying much easier.
Drying
Use your big microfibre towel. Don't scrub, just lay it flat and pull it towards you. If you leave it to 'air dry' in the Aussie wind, you'll end up with water spots that are a nightmare to remove.
Door Jams and Sills
Open the doors and wipe down the jams. Red dust loves to hide here and will ruin your carpet next time you get in.
