Why Underbody Cleaning is Essential for Your 4WD
If you take your 4WD off-road—whether on the inland tracks, at the beach or just live anywhere near the coast, there’s one thing you can’t afford to ignore: your underbody....
Salt Shift isn’t your average vehicle wash. We’re the pioneers of high-performance, corrosion-inhibiting formulas made specifically for off-road, marine, and coastal vehicles. Our ecosystem of biodegradable, Australian-made products delivers real results, fast and gives you more time to explore and less time scrubbing.
From harsh red dirt trails to salty boat ramps, our formulas break down salt, mud, and grime while helping shield your rig from long-term damage. Here’s everything you need to see to believe:
We are more than just a bottle of wash, we're a complete system engineered to clean, flush, and protect your rig from top to bottom. Our hardware and chemical formulas are designed to work together for maximum coverage and ease.
Whether you're using our Salt + Mud Kit for 4x4s, the Marine Flush Kit for engines, or our Rust Shield Kit to prevent corrosion, everything is designed to give you fast results and long-term protection.
The best part? Our products are safe on ceramic coatings, vehicle wraps, vinyl, glass, and even sensitive marine engines.
Every Salt Shift formula is tested in Australian conditions and backed by science. Using ISO-standard salt exposure guidelines, we’ve benchmarked our products against real-world coastal corrosion.
See the Difference
We get it, cleaning your 4WD, boat, or jet ski after a big weekend can be a mission. But skipping it comes with a price: rust, grime build-up, damaged coatings, and reduced resale value.
From rusty boat trailers to clogged jet ski intakes, our customers have seen firsthand how Salt Shift prevents long-term damage and keeps everything looking sharp. Even after beach driving, muddy campsites or salty boat ramps, the proof is in the rinse.
If you live within 50km of the coast, your vehicle is constantly exposed to airborne salt, even if you never drive on the beach. According to ISO corrosion standards, salt air accelerates rust up to 3x faster than inland environments.
Salt Shift’s corrosion-inhibiting formulas neutralise this threat on contact. Our products create a barrier against salt and grime while restoring that fresh, clean finish.
Every bottle is the result of over 100 split tests, real-world use, and a passion for protecting the gear you love. Salt Shift products are engineered by people who ride hard and clean smart.
Born on the coast and built for the wild, Salt Shift was made by locals who live for the outdoors. Aussie-owned, tested in the toughest conditions, and trusted by adventurers across the country.
More Than Just a Clean
Our wash doesn't just clean, it works smart. First, it loosens and lifts thick mud and grime from your vehicle’s surface. Then, it leaves behind a protective layer that helps stop salt and other nasties from sticking again.
This means faster cleaning, less effort, and long-lasting protection after every wash.
Curious if our 4x4 and boat cleaning products actually work?
Yep! Salt Shift won’t reverse rust, but itwillstop more from forming. Our corrosion-inhibited formula helps prevent further damage and protects your rig after every wash.
You’ll get the best results using a pressure washer – especially with the chassis flusher and underbody blaster. The foamers are designed to plug straight in for max power.
Depends how filthy you get. We recommend after any beach trip, muddy weekend, or if you just want that “fresh off the lot” look again.
100%. It’s tough on grime, not your gear. Our formula is pH balanced, biodegradable and safe for all exterior surfaces.
If you’ve got a 4WD, ute, or anything with an underbody worth protecting – you’re good. Our gear fits most Aussie set-ups with standard quick-connect fittings.
Regular car wash might make itlookclean – Salt Shift makes itactuallyclean. We get into the bits you can’t reach, and help stop rust before it starts.
