  • Safe on paint, chrome, plastic and coatings
  • Underbody protection that repels mud, sand and water
  • Helps prevent rust and corrosion after river crossings
  • Thick foam coverage for efficient, contactless washing
  • Compatible with both pressure washers and garden hoses

  • 1x Groundswell Underbody Protection Spray (1L)
  • 1x Groundswell Snow Foam Cannon or Adventurer Foam Cannon (for garden hose use)

How To Use

Step 1 – Clean: Fill your Snow Foam or Adventurer Cannon with Mud & Red Dirt Wash, apply foam evenly across your 4WD, and let it dwell for 2–3 minutes before rinsing.

Step 2 – Protect: Once dry, spray Underbody Protection Spray onto your chassis, suspension and exposed metal surfaces to create a barrier against rust and grime.

TIP: Apply the Underbody Protection Spray before each trip for extra defence through river crossings and muddy trails.

Australian made and tested for rugged offroad environments

The log bridge on the Old Telegraph Track (OTT) in Cape York is an iconic, precarious, and often nerve-wracking river crossing located at Cypress Creek. It consists of narrow logs, often reinforced with ratchet straps, spanning a significant drop. It is known for being shaky and requiring careful spotting to navigate safely.

Customer photo review of Triple Protection Bundle 5lt

I picked up Groundswell’s Triple Protection Bundle and I’m seriously impressed. I’ve used the Offroad Wash and Underbody Spray before and absolutely love them — after my last trip to Teewah Beach there was barely any sand left on the car! I’m heading to Fraser next, and after trying out the new Offroad Protective Sealer, I feel like my car is properly sorted and ready to go. Honestly, couldn’t recommend these products enough. Groundswell, you guys are killing it!

Premium Wash - Beach & Salt Wash

I liked this product got rid of clay that had been on the ute for few weeks seemed to dissolved it with some hard scrubing

Rodney K. 4/5 Verified

Mud Red Dirt Wash - Outback & Bush Wash

A much better way to spray the underside of your vehicle than the trigger operated sprayers. Also great that it’s solvent resistant.

David F. 5/5 Verified

Solvent Pump Sprayer 1lt

The pump up pressure sprayer is much easier to apply an even coating than the trigger type sprayer.

Excellent service provide by these guys. Snow Foam Cannon arrived just before Xmas but was damaged during transit to WA. Emailed them and a replacement was sent within a week during the busy Xmas/New Year period. New gun works brilliantly.
