Pressure Washing Tips – General Guidelines for Using a Power Washer On Farm Equipment…

Agricultural and farm machinery should be pressure washed over an unpaved area (ex. grass or gravel). Washing over unpaved surfaces allows soap filled water to soak into the ground to be filtered and eventually recharge the groundwater. You should wash your equipment no closer then 100 feet from the wellhead of a well. if you have one.  Another reason you don’t want to wash on a paved surfaces is because that water could eventually be discharged into a lake or stream through storm drains, leaving you open to environmental litigation. 

General guidelines for using a power washer in your farm equipment…

  • Wash your equipment after each use
  • Attach the water hose to your power washer. Check the fuel and oil levels. Start the pressure washer.
  • Spray your equipment with water AND detergent. Use low pressure since this way the water and the detergent will not splash away.
  • Spray from a distance of 2-3 feet from the surface. To avoid streaking, start from the lowest point on the machinery and work your way up towards the highest point.
  • Apply enough detergent to dissolve the dirt at the surface
  • Allow 5-10 minutes for the detergent to start dissolving the debris you are cleaning
  • Use  high water pressure to remove the dirt from the surface.
  • Use plenty of water to flush away the dirt. This time start from the top and work your way towards the bottom to avoid having the dirt run over the clean areas. Use a wide spray angle (25 or 40 degrees).
