Washing a 20-truck fleet in January without freezing your lines.
Winter fleet work is good business precisely because it is inconvenient. Here is how to do it without destroying equipment.
Fleet washing does not stop in winter — if anything the trucks need it more, because chloride left on a frame keeps working long after the truck looks clean. The operators who own this work are the ones who solved the equipment problem.
Heat is not optional now
Road film in winter is diesel soot, salt, and oil. Cold water at any pressure will move it around. This is the season that decides whether a hot water machine pays for itself.
The four habits
- Never leave water standing in anythingLines, pump, reels, gun. At the end of the day it comes out or it gets antifreeze in it. A cracked pump head is a several-hundred-dollar lesson and it happens overnight.
- Keep the machine running between trucksIdle circulation keeps water moving and keeps the pump warm. This is what the thermal relief valve exists to manage, so make sure yours works before the season starts.
- Deal with runoff before you startWater on a lot at 20°F becomes a liability question, not a cleaning question. Know where it is going and whether it is somebody's walkway.
- Neutralize the chloride, do not just rinse itRinsing moves salt. A neutralizer deals with it. On frames and undercarriages this is the difference between washing a fleet and maintaining one — and it is the argument that wins you the contract.
What to tell the customer
Winter washing is corrosion control, not appearance. Framed that way it stops being a discretionary line item that gets cut in January, which is exactly when it matters most. Fleet managers understand corrosion budgets.
