Pre-Soak & Chemical Arches
The pre-soak stage sets the tone for wash quality. Our car wash spray applications for pre-soak and chemical arches focus on wide, uniform coverage at low pressure so chemistry dwells evenly on every panel while controlling water and chemical use.
Why Optimized Pre-Soak Spray Matters
A vehicle-length blanket of foam loosens traffic film and salt quickly. But even a nozzle that still “looks good” can be spraying up to 30% over capacity, wasting chemicals and water without visible streaks. Routine nozzle optimization restores pattern accuracy and reduces consumption.
Challenges in Pre-Soak Car Wash Spray Applications
- Uneven coverage from incorrect angles leaves dry stripes where soil bakes on.
- Run-off and chemical waste increase when pressures are too high or nozzles drip after each cycle.
- Corrosion and premature wear accelerate when aggressive detergents attack brass or steel components.
- Clogging from recycled water adds maintenance and downtime.
Solutions for Consistent, Cost-Efficient Pre-Soak Coverage
- FullJet® full-cone nozzles create a dense, uniform curtain ideal for vehicle-wide dwell at low pressure.
- VeeJet® PVDF flat-fan nozzles resist acids, bases and oxidising agents; colour-coding simplifies angle selection - ideal for daily chemical arches.
- FloodJet® deflected flat-spray nozzles use large free passages to maintain coverage with recycled water and reduce clogging.
- FoamJet® self-aspirating nozzles build rich foam without compressed air and can be installed downstream of a check valve to prevent post-spray drain-out.
Best-Practice Tips for Pre-Soak Arches
- Select wide-angle nozzles (50–110 °) for streak-free coverage; narrower nozzle angles belong in high-impact stages.
- Operate at low pressure (+/- 1 bar) to minimize mist and run-off.
- Fit a check valve behind every nozzle to stop dripping and wasted chemistry.
- Add line or integral strainers to trap grit and extend nozzle life.
