Beach Drive Post-Wash Checklist

A bad wash technique doesn't just leave water spots—it grinds dirt into your paint, creating swirl marks that cost hundreds to fix.

Salt and sand are absolute car killers if you don't get them off properly. This checklist covers the gear and the steps you need to stop your chassis from rotting out after a weekend on the dunes.

Beach Drive Post-Wash Checklist

Aussie Conditions

Australian conditions are tougher than most—intense UV, red dust, coastal salt, and 40°C summers. European car care advice often doesn't cut it here.
Quick Summary

Look, I've seen too many 79 Series Cruisers come into the shop with 'cancer' in the rails because the owner just gave it a quick squirt at the local servo. You've gotta be thorough. This is the exact routine I use for my own rig after a run up Noosa North Shore, focusing on getting that salt out of the nooks and crannies before it bites.

01

Don't let the salt sit

Thing is, salt doesn't just sit on the paint, it finds every little weld and bolt hole. I learned this the hard way when I found surface rust on a brand new Hilux after just one week at Fraser because I got lazy with the hose. If you've been playing in the salt spray this March, you need to get onto this as soon as you get home. No dramas if you're tired, but your chassis will thank you.

Essential Gear & Materials

What You'll Need

0/8
Pressure Washer — Doesn't need to be a beast, but a decent electric one makes life easier.
Underbody Water Broom — Best fifty bucks you'll ever spend. It saves your back and gets way more sand out.
Salt Neutraliser (e.g., Salt-Away or Bowden's Own) — Honestly, I wouldn't bother with just soap. You need something that actually breaks down the salt crystals.
PH Neutral Snow Foam — To lift the abrasive sand off the paint without scratching it to bits.
Soft Bore Brush — For getting into the wheel nuts and around the fuel cap.
Microfiber Wash Mitt — Use a dedicated one for the bottom half of the car. It'll get filthy.
Degreaser — To clean up any greasy sand stuck to the diffs or gearbox.
Large Microfiber Drying Towel — Don't use a chamois, they're rubbish for modern clear coats.

Pre-Start Checklist

What You'll Need

0/3
Engine Cool Down — Give it 20 mins. Spraying cold water on a hot turbo or manifold is a recipe for disaster.
Check for 'Hidden' Sand — Open the doors and check the sills and the rubber seals. Sand loves hiding there.
Remove Side Steps/Plates — If you've got bash plates and you've been deep in it, consider dropping them. Sand traps moisture against the metal.

The Step-by-Step Clean

Tap each step to mark complete
01

The Underbody Flood

Start here. Use the water broom or a high-pressure nozzle to blast every rail, crossmember, and the top of the fuel tank until the water runs clear.

02

Engine Bay Blowout

Mist the engine bay lightly (don't drench the electrics). I use a damp rag to wipe salt spray off the battery terminals and intake hoses.

03

Salt Neutraliser Application

Chuck your salt neutraliser in a foam cannon or sprayer. Coat the whole undercarriage and the paint. Let it dwell for 5-10 mins but don't let it dry.

04

Contactless Snow Foam

Foam the whole car. This encapsulates the sand so you don't drag it across the paint when you start scrubbing. Rinse it off thoroughly after a few minutes.

05

Two-Bucket Wash

Now do a proper wash with a mitt. Work from the top down. I always leave the wheels and lower sills for the very last step.

06

Flush the Brakes

Spend extra time on the calipers and rotors. Salt build-up here can cause your pads to seize or your rotors to pit prematurely.

05

Final Inspection

What You'll Need

0/4
Chassis Rails — Stick a finger in the holes in the frame. If it feels crunchy, keep rinsing.
Wheel Arches — Check behind the plastic liners. A customer once brought in a Ranger with 5kg of sand stuck behind the guard!
Door Jambs — Wipe them down. Salt spray drifts everywhere, even inside the doors.
Radiator Fins — Ensure no salt or sand is clogging the cooling fins. Use low pressure here so you don't bend them.

Watch Out

Never use a high-pressure wand directly on wheel bearings or electrical sensors at close range, you'll force salt inside them. Also, avoid washing in the direct midday sun; in an Aussie March, the water will evaporate instantly and leave nasty spots on your glass.
06

Expert Opinion

Reckon if you do this every time you hit the coast, your car will last ten times longer. Most people skip the salt neutraliser, but honestly, it makes a massive difference in preventing that 'white crust' you see on aluminium parts. Anyway, get it done, then go have a cold one. Cheers!
