Weed & Seed Cleaning Standards

At CST Hire, our weed and seed cleaning standards are designed to help reduce the spread of invasive weeds, seeds, soil-borne contaminants and organic matter across job sites, roads, agricultural land and environmentally sensitive areas.

About Our Process

CST Hire follows a practical and thorough cleaning approach across our hire fleet, with attention given to the areas where soil, seeds and plant matter are most likely to collect.

  • Removal of soil, mud, grass, seeds and plant debris from external vehicle surfaces
  • High-pressure washdown of key areas where contamination may build up
  • Inspection of tyres, wheel arches, underbody areas, trays, steps, guards and chassis rails
  • Cleaning of bumpers, grills, mudguards, toolboxes, tow points and storage areas
  • Attention to hidden collection points, joints, crevices and hard-to-reach areas
  • Internal cabin checks where required for loose dirt, organic matter or site contaminants
  • Final inspection before fleet is released for project use

This process helps ensure CST Hire vehicles are presented to a high standard and are ready for use across projects where weed hygiene and biosecurity expectations apply.

Vehicles and machinery can collect soil, seeds, mud, plant material and other contaminants during day-to-day operation, especially when working across unsealed roads, remote access tracks, pastoral land, civil construction areas and major infrastructure projects.

If not properly managed, this material can be transferred from one location to another, creating biosecurity risks for landholders, contractors, project owners and local environments.

That is why CST Hire places a strong focus on fleet cleanliness, inspection and preparation before vehicles are deployed to site.
