Post-Beach Salt and Sand Removal

Most car owners make this harder than it needs to be. Here's the straightforward approach that actually works—no fluff, no upselling.

Driving on the sand is a blast, but the salt will eat your chassis alive if you're lazy. Here is exactly how to flush the muck out and save your paint from the Aussie sun.

Post-Beach Salt and Sand Removal

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, I've seen too many good rigs ruined by a 'quick rinse' at the local servo after a weekend at Fraser or Robe. Salt and that fine coastal sand get into every crevice, and with our March heat still hitting 35-40 degrees, it bakes on fast. This is the routine I use for my own 4x4 to keep the rust at bay and the paint from clouding over.

01

The Gear You'll Need

What You'll Need

0/8
A decent pressure washer — Doesn't have to be a beast, but you need more poke than a garden hose.
Salt-neutralising wash — I reckon Salt-Away or Bowden's Own Salt Sifter are the only ones worth your coin.
Underbody water broom or angled nozzle — Your back will thank me later. Don't just crawl under there with a hose.
Snow foam cannon — Essential for lifting that abrasive sand without scratching the clear coat.
Soft wash mitt — Microfibre only. Toss those old sponges in the bin.
Two buckets with grit guards — Trust me, you'll see the sand at the bottom of the bucket and be glad it's not on your paint.
Stiff-bristled tyre brush — For scrubbing the salt spray out of the sidewalls.
Large microfibre drying towel — To stop those nasty water spots forming in the March sun.
02

Pre-Start Checklist

What You'll Need

0/4
Engine is cool to the touch — I once saw a mate crack a manifold spraying cold water on a hot engine after a long haul. Not pretty.
Parked in the shade — Never wash in direct sun if you can help it, especially with the UV we get this time of year.
Windows and sunroof tightly shut — Seems obvious, but we've all made that mistake once.
Floor mats removed — Give them a shake and a vacuum separately.

The Step-By-Step Process

Tap each step to mark complete
01

Dry Sand Removal

Give the whole car a heavy rinse with plain water first. Don't touch the paint yet! Just blast the loose chunks of sand off the panels and out of the wheel arches.

02

Underbody Assault

Chuck your underbody attachment on. Spend a good 15 minutes here. Focus on the chassis rails, inside the bumpers, and above the fuel tank where salt loves to hide.

03

Salt Neutraliser Application

Mix your salt-neutralising wash and foam the entire car, including the undercarriage. Let it dwell for 5 minutes, but don't let it dry. This breaks the ionic bond of the salt.

04

Contact Wash

Use the two-bucket method. Start from the top and work down. Rinse your mitt after every panel to ensure you aren't dragging leftover sand across the paintwork.

05

Wheel and Tyre Scrub

Salt eats alloy wheels for breakfast. Get the brush into the lug nuts and behind the spokes. Give the tyres a good scrub to get that beach-grey look off them.

06

Engine Bay Wipe-down

Don't go nuts with the pressure washer here. Just a damp cloth to wipe salt spray off hoses and the battery. I've found salt in engine bays 50km inland before.

04

Final Inspection Checklist

What You'll Need

0/4
Check the door sills and jams — Wipe away any trapped sand or salt water that collected there.
Inspect the radiator core — Make sure it isn't clogged with salty sand or dried-up March bugs.
Touch-test the paint — If it feels gritty, you missed a spot. Rinse and repeat.
Apply a spray sealant — I'd use something like Gtechniq C2 or Meguiar's Ceramic Spray Wax to give it some UV protection for the drive home.

Watch Out

Look, whatever you do, do NOT use dish soap. It'll strip any wax you've got and leave your paint vulnerable to the salt. Also, watch out for those bat droppings if you're parked under trees at the campsite, they'll burn through your clear coat in hours in this heat. Get 'em off immediately with some quick detailer.
