Getting Sand and Salt Out of Your Pride and Joy (Mar 2026)

Aussie Conditions

Living near the coast? Salt air corrodes metal and degrades rubber seals. A fortnightly wash underneath is essential, not optional.
Quick Summary

Look, we've all been there, a weekend at Fraser or just a quick run down to the local beach and suddenly your car looks like a sandpit. This guide is for anyone who loves the coast but hates the thought of rust and scratches. I'll show you the fastest way to get it sorted so you can get back to your Sunday arvo beer.

01

The Problem with the Beach

Look, sand isn't just annoying, it's basically tiny shards of glass. If you just grab a rag and start wiping, you're going to sandpaper your clear coat. I learned this the hard way on a black Commodore years ago; one 'quick wipe' and the bonnet looked like I'd used a Scotch-Brite pad. Throw in the salt spray from the Pacific or the Southern Ocean and you've got a recipe for rust that'll devalue your rig faster than a blown head gasket.

Air is Your Best Mate

Before you even touch a vacuum, use a leaf blower or compressed air on the interior. Open all the doors and blow the sand out from under the seats and tracks. It gets 80% of the grit out without you having to grind the vacuum nozzle into the carpet fibers. To be honest, I reckon a cheap Ozito blower from Bunnings does a better job on sand than most $500 vacuums.

The Infinite Rinse

On the exterior, don't even think about touching the paint with a sponge until you've rinsed it for at least 10 minutes. Use a pressure washer if you've got one, but keep a bit of distance. You want to flush the sand out of the window seals and door shuts. If you've been on the dunes, spend double the time on the undercarriage. Salt hides in the chassis rails and it'll rot your frame from the inside out while you're not looking.

Brush Before You Suck

For the stubborn sand stuck in the carpet pile, use a stiff nylon brush (or even a cheap drill brush attachment). Agitate the carpet while you've got the vacuum running right next to it. It 'pops' the sand grains up so they can actually be sucked away. A customer once brought in a Ranger that looked like a beach volleyball court, this was the only way to get it back to factory fresh.

Neutralise the Salt

Standard car soap doesn't always cut it with heavy salt crust. I'm a big fan of salt neutralising washes like Salt-Away or even Bowden's Own Lazy Wax for a bit of post-wash protection. It chemically breaks down the salt so it actually flushes off rather than just getting moved around. I wouldn't bother with those 'automatic' underbody washes at the servo, they usually just spray recycled, salty water back into your nooks and crannies.

The Sand-Busting Kit

What You'll Need

0/5
A decent leaf blower — Saves your back and your vacuum bags.
Stiff nylon upholstery brush — Essential for 'flicking' sand out of the carpet weave.
Pressure washer with a 40-degree nozzle — Perfect for flushing the chassis without stripping paint.
Salt neutraliser solution — Vital if you've been driving through salt water or spray.
Microfibre wash mitt — Throw it in the wash after every beach job, sand stays trapped in them.

Watch Out

Never use a chamois or a 'leather' to dry a car that's been near the beach. If even one grain of sand is left, you'll drag it across the whole car and leave nasty swirl marks. Also, don't wait a week to wash it. In our 40-degree heat, salt and UV work together like a pair of vandals to kill your clear coat. Wash it the same arvo you get back, no dramas.
03

Common Sand Questions

Can I just use the high-pressure hose at the servo?
Yeah, it's better than nothing, but most of them don't have the reach to get deep into your chassis rails. Use it for a quick rinse, then do a proper job when you get home.
How do I get sand out of my perforated leather seats?
This is a nightmare. Use a soft vacuum brush attachment and gently 'thump' the seat with your hand while vacuuming. It creates a vibration that bounces the sand out of the holes. Don't use a toothpick, you'll just stretch the leather.
What's the best way to stop sand sticking in the first place?
A good ceramic coating or a high-quality sealant like Gtechniq C2 makes the surface 'slicker', so sand and salt don't bond as easily. It won't stop it entirely, but it makes the wash-down ten times easier.
