How to Clean and Protect Your Snorkel and Roof Rack (Mar 2026)

Red dust, creek crossings, and corrugated roads don't just test your 4WD—they test your cleaning game. Most people get it wrong.

Off-road gear takes a beating from the Aussie sun and red dust. Here is how to get the grit out of your snorkel and the salt off your rack without ruining the finish.

How to Clean and Protect Your Snorkel and Roof Rack (Mar 2026)

Aussie Conditions

Aussie red dust is iron-rich and bonds to paint. A regular rinse won't cut it—you need proper pre-wash and pH-neutral soap to avoid scratching.
Quick Summary

Look, we all love bolting gear to our rigs, but most blokes forget that snorkels and roof racks are absolute magnets for the worst Australia has to throw at us. Whether it's red dust from a Kimberley trip or salt spray from a weekend at Fraser, this gear needs more than a quick splash at the servo. I'm going to show you how to deep clean these bits properly so they don't fade into a nasty grey mess by next season.

01

Real Talk About Off-Road Gear

Right, so you've spent a few grand on a Safari snorkel and a Rhino-Rack, and they looked mint for the first month. But now? If you've been anywhere near the red centre or even just parked under a gum tree for a week, they're probably looking a bit sad. After 15 years in the trade, I've seen so many textured plastics turn chalky and white because of our brutal UV. It's not just about aesthetics, either. A snorkel head full of dead locusts or thick dust is literally choking your engine. I learned this the hard way when a mate's Hilux started blowing black smoke halfway to Broome, turned out the pre-cleaner was more mud than mesh. Cleaning this stuff isn't hard, but you've gotta use the right gear or you'll just end up staining the plastics even worse. Let's get stuck in.

The Gear You'll Actually Need

What You'll Need

0/8
A sturdy step ladder — Don't stand on your tyres; I've seen too many blokes slip and dent their panels.
Soft-bristle detailing brush — Something like the Bowden's Own Boar's Hair brush is perfect for the rack channels.
All-Purpose Cleaner (APC) — Meguiar's APC or even a diluted Sugar Soap mix for the really greasy stuff.
Microfibre wash mitt — One you don't mind getting a bit dirty.
Non-acidic wheel cleaner — Surprisingly good for breaking down baked-on red dust on powder-coated racks.
Plastic trim restorer — Solution Finish is the only one I trust for faded snorkels. Avoid the greasy silicone stuff.
Pressure washer — Keep it on a wide fan setting, not a jet stream.
A long-handle brush — For reaching the middle of the roof rack without leaning on the car.

Preparation

Tap each step to mark complete
01

Cool it down

Never wash your gear when it's been sitting in the 40-degree sun. The chemicals will flash dry and leave spots. Move it into the shade or wait for the arvo.

02

Check your seals

Make sure your snorkel head is tight and the airbox drain plug is clear. You don't want to accidentally flood your intake while you're getting enthusiastic with the hose.

03

Dry brush first

If you've got thick red dust, use a vacuum or a dry brush to get the loose stuff off before adding water. Adding water to red dust just makes mud that hides in every crevice.

04

The Deep Clean Process

Tap each step to mark complete
01

Rinse the heavy grit

Give the rack and snorkel a thorough rinse. Focus on the underside of the rack and the mounting brackets where salt and mud love to hide.

02

Snorkel head removal

Loosen the worm drive clamp and pop the snorkel head off. Trust me, it's the only way to clean the mesh properly. A customer once brought in a Ranger that had a literal bird's nest starting in there.

03

Degrease the rack

Spray your APC onto the roof rack. Work in sections. Use your long-handle brush to agitate the powder-coated surface. If you've got T-slots, run the brush right through them to clear out spiders and dirt.

04

The 'Red Dust' trick

If the rack still looks orange after a wash, spray some non-acidic wheel cleaner on a small patch. The iron-out properties often help lift that stubborn outback staining. Rinse quickly!

05

Cleaning the snorkel body

Use a wash mitt and a good car soap (like Bowden's Nanolicious). Don't use a scrubbing brush on the snorkel body or you'll scratch the plastic and make it look dull.

06

Detailing the mesh

Take that snorkel head you removed and use a soft brush with soapy water to clean every single hole in the grate. This is where the bugs live.

07

Rinse thoroughly

Rinse everything until the water runs clear. Pay attention to the roof channels under the rack mounts, that's where rust starts if salt gets trapped.

08

Dry it off

Use a dedicated drying towel or a leaf blower. Don't let it air dry in the sun or you'll get water spots on your nice black finish.

09

Inspect for damage

While it's clean, check your rack bolts. Off-roading rattles everything loose. Give 'em a quick nip with a spanner if they've backed off.

Watch Out

Don't get too close to the snorkel intake or the door seals with a high-pressure washer. I've seen blokes blow water straight past the snorkel head and into the air filter. A wet air filter is a great way to limp home in limp mode.

The Gum Tree Nightmare

If you've got dried sap on your aluminium rack, don't scrape it. Put a bit of hand sanitiser (the alcohol-based stuff) on a rag and let it sit on the sap for 30 seconds. It'll melt right off without hurting the powder coat.
05

Protection is Everything

Once it's clean, you've gotta protect it, otherwise you'll be doing this again in two weeks. For the snorkel, I don't bother with those 'tyre shine' sprays; they're oily and just attract dust. I use a dedicated trim sealant like Gtechniq C4 or Solution Finish. It actually bonds to the plastic. For the roof rack, if it's powder-coated aluminium, chuck a bit of spray wax or a ceramic sealant on it. It makes the bugs and bird droppings much easier to wash off next time. Honestly, the missus' car gets the fancy wax, but the 4x4 gets the heavy-duty ceramic spray because I'm lazy and don't want to scrub it every weekend. And yeah, that's pretty much it for the protection side of things.

Common Questions

Can I go through an automatic car wash with a roof rack?
I wouldn't risk it. Those big brushes love to get snagged on rack corners and can rip your light bars or awnings right off. Plus, they never actually clean the top of the car anyway.
How do I get the 'chalky' look off my old snorkel?
If it's already grey and chalky, a wash won't fix it. You need a trim restorer like Solution Finish to put the black pigment back in. Don't use a heat gun; it's a temporary fix that actually makes the plastic more brittle over time.
Should I wax my roof rack?
A spray sealant is better. Traditional paste wax is a nightmare to get out of the textured finish and T-track channels.
Is red dust permanent?
If left for years, it can stain the paint and plastic. But if you use a dedicated iron remover or a decent APC early enough, it'll come off. Just don't let it bake in the sun for six months.
