What You'll Learn
Aussie Conditions
Look, if you've done a run through the Red Centre or even just a weekend at the beach, your vents are likely packed with fine silt or salt spray. I've spent 15 years cleaning out the guts of 4WDs, and honestly, most people just spray some cheap silicone on top and call it a day, which just makes the dust stick worse next time. This guide is for the blokes who want to actually get the grit out properly before the autumn rains hit.

The Step-by-Step Method
The Dry Vacuum
Run the vacuum brush over the vents while they're closed, then open. Get the loose stuff out first before you add any moisture at all.
Agitate with Brush
Spray a tiny bit of APC onto your brush (not the vent!). Work it into the corners. I learned the hard way: never spray liquid directly into the dash.
The Blow Out
While agitating with the brush, use compressed air to blow the dust out. Keep the vacuum nozzle right next to the vent to catch the cloud.
Detail the Slats
Use your foam swabs dampened with APC to wipe each individual slat. This gets that 'film' of dust that brushes miss. It's tedious, but worth it.
Steam Sanitise (If needed)
If you've got a steamer, give it a quick blast. It kills bacteria and loosens grime in the ducting. My missus loves this part because it kills the 'wet dog' smell.
Dry and Protect
Wipe everything dry with a fresh microfibre. Apply a matte UV protectant to the visible edges to stop the Aussie sun from cracking the plastic later.
