Just washed the Jeep, once dried I sprayed the under carriage per the instructions. I did get some on the fenders which are powder coated steel and faded they now look new as does the under side. This stuff just works the only downside is it took 3 days to dry and I attribute that to the humidity but it was definitely worth it!
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:
Real rigs, Real results
Built as a System, Not Just a Soap
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.

See the Difference
With Salt Shift vs. Without
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.
Coastal Corrosion is Real
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.

Perfect off-road wash kit for my Defender!!!
Awesome product 👍🏾 Easy to use and does a great job!
Works well
Living in the PNW means putting the rig through just about everything—mud, sand, rain, river crossings, and plenty of wet roads. That’s why I’ve been really impressed with Salt Shift. Their products do more than just one thing. They help repel mud and sand from the chassis, make cleanup way easier (most of it blows right off with my blower), and most importantly, help protect the truck from rust and corrosion. The protection lasts for weeks and doesn’t just disappear after a little rain or water. When I’m ready to remove it, I use a chemical wash. I’m pretty picky about what I recommend, especially when it comes to products I use on my own rig. Salt Shift is something I’ll stand behind. Thanks Salt Shift for making a product that actually works. 🤙
Great bit of kit. Works well on my caravan and 4wd.
Works so well , will be getting more
Top quality products
To me I expected a bit more cleaning from this product , it was a bit of a disappointment to be fair .
Perfect
Fast shipping to the US and works great
Good stuff
All good, nice quality
Used all nozzles on my pressure washer, fit for purpose and good quality.
On time great product
The absolute best of the best — hands down! This stuff is legendary for a reason. Blasts away salt, mud, and grime while leaving a protective layer that stops surface rust before it even starts. If you care about your 4WD, this is non-negotiable. Total game-changer for undercarriage protection. 5 stars, no question!
Perfect fit, tough, and no kinks! Solid brass fittings, bright fluorescent green so you can't lose it, and flexible enough to get where you need it. Built to last — no twisting, no collapsing under pressure. Exactly what you need. 5 stars!
Brilliant bit of kit! Simple, tough, and blasts salt & grime from chassis rails perfectly. You can see it working — flushes out all the crap you can't reach. Every 4WD needs one. 5 stars! ⭐⭐⭐⭐⭐
Complete undercarriage solution — brilliant! Everything you need in one kit, built tough, and makes the tough jobs easy. If you own a 4WD, you NEED this. 5 stars all day! 🏆🚙
Dual-sided design: soft chenille for gentle washing + textured scrubbing side for tougher grime. One mitt, two jobs — perfect for a quick, thorough clean. 🧽✨
delivered a fantastic job

Previously flushed out and thought the chassis was clean. When I used the flusher it was amazing how much more mud was removed. Great product.
