One bottle, whole rig

One wash. Every surface.

Paint & clear coat
Ceramic, PPF & wraps (1:10)
Glass & mirrors
Alloys & tyres
Plastics, trims & checker plate
Canopies & roof racks
Chassis & underbody
Engine bay (as directed)

Plus the daily driver and the gear it tows: camper trailers, caravans, painted & alloy boats, bikes. Weekend rig or school-run hatchback, it's the same weekly wash. Gelcoat or fibreglass hull? Use our Marine Series, the same chemistry made for those surfaces. Heavy brake dust? Pair with Wheel Wizard for the deep clean.

Why 4WDs rust after washing

Think hosing it off is enough? Unfortunately not...

There's a variety of different salt compounds in the ocean. Some wash away with water & some do NOT. These water insoluble compounds are called Ionic Salt compounds & their structure cannot be broken up with just water! They sit in your chassis rails, seams & bolt threads, drawing in moisture & corroding your 4WD from the inside out. That's why almost every beach-driven 4WD has some degree of surface rust!

And it's not just a beach problem. Clay & bog mud pack into your chassis rails like wet concrete. They hold moisture & dissolved salts against bare steel for weeks, block your drain holes & keep corroding long after the outside looks dry. Victoria's High Country is one of the biggest 4WD destinations in the country without a single beach run & clay-packed rails rust rigs there just the same.

That's exactly why we engineered Salt Exterminator: to dissolve the salts water can't touch, break down packed mud with Deep Expansion Technology & leave chemical + physical rust inhibitors working on the surface after you rinse!

So when you come home from the beach or the bush, there are no nasty rusty surprises waiting underneath!

Salt dissolving agents
Break up the ionic salt compounds plain water can't touch, so they rinse away instead of staying in your rails.
Chemical + physical rust inhibitors
Left working on the surface after you rinse, your first layer of defence between washes.
Deep Expansion Technology
Swells into packed mud and clay, lifting and loosening it so the pressure washer can carry it away.

Cost per wash

$45-55 at the drive-thru. $1.30 at home.

Drive-thru wash

$45-55

Every visit. High-pressure recycled-water jets pushing yesterday’s salt back into your rails. Sand and mud still left behind.

Salt Exterminator at home

$1.30 per wash (5L)

You control every pass. Rust inhibitors left working when you’re done. One 5L bottle is about a year of proper washes.

FAQ

Thousands of real 4WDers. Here’s what they reckon.

✦ WHAT REVIEWERS SAY

Reviewers consistently say mud, dirt and grime rinse off without scrubbing, washing takes about half the time, and the finish stays cleaner for longer between washes. Plenty bought sceptical after seeing the ads and now restock in bulk, using it on boats, caravans, bikes and the daily car as well as the 4WD. A handful note baked-on bugs still want a quick mitt pass, which is exactly what the directions say.
