In a depot that runs several delivery vans on one route plan, the wash bay is rarely the problem — until it is. A slot that should take twenty minutes quietly becomes forty, and the vans leave the yard late. Estimating cleaning time for delivery-van exteriors starts with an honest question: how long do one operator, one machine and one vehicle actually need? The answer rests on four inputs you can measure this week, and those measurements are what a purchasing team should put into a quotation request instead of a guess.
1. Measure each van type, not an averaged fleet
Time scales with the surface the operator has to cover. A small panel van, a mid-size box van and a high-roof transit van are three different jobs, even when they sit on the same fleet list. Before you publish a standard, record one complete cycle for every body style you actually own: the smallest panel van, the mid-size van and the largest body in the yard. Keep those figures apart. Blending them into one "average van" number is the quickest way to a wash schedule that falls apart in the second week of operation.
Then break the exterior into zones: roof and upper panels, side panels and doors, rear doors and hinges, wheel arches, and the lower sill. Roofs and rear doors carry the heaviest film, because runoff and exhaust deposit there, so they need a second pass. Writing the zones down produces a number that survives a change of operator and a change of shift.
2. Judge the soil, because it sets the number of passes
Loose dust and road spray lift in one pass. Film that has been baked on — brake dust across the front panels, oil along the lower sill, spilled load residue under the rear doors — needs heat applied first and a second pass to lift what the heat has released. With a commercial steam cleaner, the planning rule is simple: one pass for loose soil, two passes for bonded film, with the dwell time between them counted as working time instead of waved away.
Vans working construction sites, cold-chain depots and food distribution arrive in a different condition from vans doing office runs. Base the estimate on the dirtiest vehicle in the fleet rather than the cleanest, and the schedule will still hold in winter.
3. Set the drying rule before you estimate anything else
Drying is where estimates fail. A van that leaves the bay wet carries water spots into the next customer meeting, and re-wiping a wet panel costs more than the wash did. Decide in advance which surfaces are wiped dry and which may air dry, then put that decision into the written standard operators follow. On a fixed steam cleaning machine such as the HW02, the dry-steam mode shortens this stage, because it leaves far less moisture on the panel than a rinse does.
If the fleet carries branded livery, treat the vinyl wrap as its own surface. Wrap edges lift when pressure is aimed straight at them, so the estimate needs a gentler pass over wrapped areas rather than one pressure setting across the whole body.
4. Add the walking distance and the water point
Machine cycle time is only part of the total. Add the walk from the bay to the water point, the time to refill, and the time to move the unit between bays. With a fixed unit such as the HW02, the 80 L tank and the tap-water inlet let one fill cover a run of vehicles, provided the bay layout keeps the hose in reach. With a mobile unit, the refill and charge cycle belongs in the daily plan. An extra thirty metres of walking per vehicle multiplies across a shift, and that distance is part of the estimate.
Write the result as three figures per vehicle type: hands-on time, machine dwell time and movement time. Add them, then multiply by the number of vehicles in the shift.
A trial you can run this week
Take one van, one operator and one machine. Time the zones from step one, count the passes from step two, and record the drying decision from step three. Repeat on the same vehicle three times and take the middle result. That middle figure is the baseline your fleet can plan against, and it is the figure to place in front of a supplier when you ask which machine, tank size and bay layout will hold it.
PowerDe's cleaning range covers both arrangements. Where the van wash is a fixed station, the high-pressure steam cleaning machine page lists the HW02 with dry and wet steam modes, an integrated vacuum, and protection features covering leakage, short circuit, high temperature, high voltage and water shortage. Where vehicles are cleaned where they park, the mobile steam cleaning machine range offers driving-style and hand-pushed units built for narrow garages and tight parking spaces. Send the three measured figures with your enquiry, and the conversation moves from specifications to scheduling — which is the conversation that decides whether the vans leave on time.
