Keeping the Dust Off: Real World Protection for Aussie Cars (Mar 2026)

Never, ever wash your car while the bonnet is hot. I've seen guys at the servo trying to wash their cars after a long run and the soap just bakes on instantly. Park it in the shade, let it cool down for an hour.

Start with the wheels. If you do them last, you'll splash dirty brake dust all over your clean paint. Use a separate brush and bucket for this.

Before you touch the paint with a mitt, rinse the living daylights out of it. You want to flush as much loose dust and sand out of the window seals and badges as possible.

If you've got a foam cannon, use it. If not, just spray a bit of your soapy mix over the car and let it sit for 2-3 minutes. This softens the Aussie bug guts and bird drops so they don't scratch when you wipe.

Using your two buckets, wash from the top down. Be gentle. You're not scrubbing a burnt pot; you're gliding over the surface. Rinse your mitt in the clean water bucket after every panel.

Spray your iron remover on the paint. If it turns purple, that's the metallic fallout dissolving. Give it a rinse after a few minutes. Don't let it dry!

This is the secret sauce. Rub your clay mitt over the wet paint. If the paint feels 'bumpy' or sounds like sandpaper, keep going until it's silent and smooth. This removes the 'anchors' that dust likes to cling to.

Use a large microfiber drying towel. Pat the car dry rather than dragging the towel. We want a perfectly dry surface for the sealant.

Grab your SiO2 sealant (like Gtechniq C2). Spray it sparingly onto a microfiber applicator or towel, then wipe it onto one panel at a time. A little goes a long way, don't overdo it or it'll streak.

Immediately buff the panel with a fresh, dry microfiber towel. You'll feel the surface become incredibly slick. If it's a black car, double-check for high spots in the light.

Don't forget the inside of the doors. Dust loves to settle in the jams and then blow into the cabin the second you open the door. Give them a quick wipe with the sealant too.

I usually chuck a bit of sealant on the side windows too. It helps the dust roll off when you put the windows down.

Use a water-based tyre shine. Oil-based ones are 'sticky' and will turn your tyres brown with dust within ten minutes of driving.

Let the car sit in the shade (or garage if you're lucky) for at least 2-4 hours. The sealant needs time to cross-link and harden properly.

Take a lap around with a torch (or your phone light). Look for any hazy spots and give them a quick buff.
