There’s nothing quite like the thrill of a muddy 4WD trip kicking up dirt, splashing through puddles, and taking on Australia’s toughest terrain. But once the fun ends, it’s time to clean up. Because if you leave all that mud and moisture on your rig, you’re inviting rust, corrosion, and long-term damage.
Here’s your step-by-step guide to protecting your 4WD from rust after a muddy off-road mission.
1. Start With a High-Pressure Rinse
Before you reach for any cleaners, give your 4WD a full rinse using a high-pressure hose. Focus on your wheel wells, underbody, chassis rails, and any spots where mud tends to cling. This helps dislodge the heavy muck and gets you ready for a deeper clean.
2. Use a Salt-Neutralising Wash Detergent
If you’ve driven through salty water or beaches, rust prevention becomes even more important. Use a salt-neutralising 4WD wash detergent like Salty Captain’s Salt Wash Detergent. It’s specially designed to break down salt and grime while being safe on paint, metal, and plastics.
Foam it using a foam gun, let it sit for a minute, and rinse thoroughly.
3. Flush Your Chassis Rails
Mud and salt don’t just stick to the outside; they creep inside your chassis rails and underbody cavities, places you can’t see or reach easily. That’s where a 4WD chassis flusher like Salty Captain’s Chassis Grenade comes in.
Just connect it to your hose and Musket foam gun, and let it flush out the buildup from inside your chassis rails massively reducing the risk of rust in those hidden spots.
4. Degrease and Protect Key Areas
Use a multi-purpose degreaser like Grease Attack for your engine bay, suspension, and underbody. It removes oil, grease, and stubborn mud while being safe on critical components. Follow up with a UV and corrosion protectant spray to shield plastics and metal surfaces from the elements.
5. Dry It Off Completely
Leaving water to sit on your 4WD can cause spots and worse, rust. Use a drip dry spray like Salty Captain’s Drip Dry to help water slide right off the surface and speed up drying. You can also use a leaf blower or compressed air to blow out water from tricky areas.
Final Tips
- Clean your 4WD after every muddy or beach trip don’t wait days.
- Always flush your chassis rails after beach or saltwater exposure.
-
Use protective coatings regularly on underbody parts.
