Undercarriage Washing & Rinsing
Road salt, mud and brake dust accumulate where you can’t see them: the vehicle’s underside. Our car-wash spray applications for undercarriage washing and rinsing pair high-flow, medium-angle jets for powerful cleaning with a controlled fresh-water rinse that leaves chassis components salt-free and corrosion-resistant - while keeping water and energy use in check.
Why Optimized Undercarriage Washing and Rinsing Matter
A one-millimetre salt crust can trap moisture and kick-start rust. Effective washing breaks that crust; a correctly staged rinse flushes residual chemicals so they don’t continue corroding steel and aluminium after the wash. Done right, fresh-water use is limited and vehicle life is extended.
Challenges in Undercarriage Spray Applications
- Shadow zones: Suspension arms and cross-members create pockets standard sprays never reach.
- Clogging and wear: Grit in recycled water erodes nozzle orifices, reducing impact and widening spray.
- Chemical carry-over: Detergent left behind attacks bare metal unless thoroughly rinsed.
- High pump load: Continuous upward flow can over-size pumps and raise electricity costs.
Solutions for Complete, Cost-Efficient Cleaning & Rinsing
- Medium-angle VeeJet® flat-fan nozzles (50° - 110°) mounted in opposed pairs ensure cross-fire coverage of wheel wells, axles and chassis rails.
- Deflected P FlatJet® nozzles (15° - 50°) deliver high-impact jets with large free passages that resist clogging when recycled water is used. Ideal for stubborn mud on SUVs and 4x4s.
- Staged reclaim/fresh-water design: start the cycle with filtered recycled water for heavy soil removal, then switch to fresh water for the final rinse to ensure spot-free results and longer nozzle life - dramatically reducing fresh-water usage.
- Ceramic or tungsten-carbide inserts extend service life up to 15x when using recycled water.
Best-Practice Tips for Undercarriage Washing and Rinsing
- Mount nozzles 200-300 mm from the chassis for optimal impact.
- Maintain 25% spray overlap between adjacent nozzles.
- Use fresh-water rinse bars with wider angles (80° - 110°) to sweep detergent off in one pass.
- Replace nozzles when flow rises 10% above spec.
- Install mesh inline strainers and clean weekly.
