North Texas weather is hard on vehicles that live outside. In a single year a fleet can go from yellow pollen dust to hail-season mud to baked-on summer grime and back again. The good news is that the seasons are fairly predictable, so you can plan your wash schedule around them instead of reacting after the fleet already looks bad.
Here's how each season affects fleets, and what to do about it.
Spring: pollen
From late winter into spring, trees across North Texas release pollen, with oak among the heaviest. Grass pollen follows later in spring and into summer. If you've parked outside in March or April, you've seen the result: a yellow-green film on every horizontal surface.
Why it matters for fleets:
- Pollen is most visible on dark vehicles and glass, and dealer lot inventory shows it the most.
- Pollen mixed with morning dew or light rain turns into a sticky film that's harder to rinse off than dry dust.
- Windshields coated in pollen are a visibility issue, not just a looks issue.
What to do:
- For dealer lots and light-colored fleets, plan on extra washes during peak pollen weeks. A light Level 1 wash with a spot-free rinse is usually enough. Our dealership lot washing page explains how that works.
- Wash in the evening or overnight, after the day's pollen has settled.
- Don't wait: pollen that has been rained on a few times is harder to remove.
Spring and early summer: storms
Spring is severe-weather season in North Texas, with thunderstorms, heavy rain and sometimes hail. Storms can come back in the fall too.
Why it matters for fleets:
- Rain doesn't wash vehicles clean. It picks up dust on the way down, splashes grime off the pavement, and leaves spots as it dries.
- Job sites turn to mud. Trucks leaving construction sites around fast-growing areas like Celina and Prosper carry clay onto the roads and into their wheel wells.
- Hail can damage vehicles, and dents and cracks are easier to spot and document on a clean vehicle.
What to do:
- Plan light washes after rain, not before. We move Level 1 and Level 2 washes to after the rain when the forecast allows.
- Switch muddy trucks to a heavy-mud wash with an undercarriage flush during wet stretches. See construction and dump truck washing and equipment washing.
- After a hailstorm, a wash makes damage easier to see and photograph for insurance claims.
Our subscription customers get a Rain Guarantee: if it rains within 48 hours after a wash, we come back and re-rinse at no charge. It's there because rain right after a wash is frustrating, and it happens a lot in spring.
Summer: heat
North Texas summers are long and hot. That changes how washing should be done:
- Soap and water dry fast on hot panels in direct sun, which can leave streaks and spots.
- Bug splatter builds up on front ends and grilles during summer driving. Like bird droppings, it's best removed soon rather than baked on for weeks.
- Crews and vehicles both do better out of the midday sun.
What to do:
- Wash at night or early in the morning. It's cooler, and vehicles are usually parked anyway.
- Use a spot-free final rinse so any water left on the vehicle dries clean.
- Pay extra attention to front ends on highway trucks and vans.
Fall: the second season
Fall usually brings milder temperatures and some rain, and ragweed pollen for allergy sufferers. It's a good time to reset the schedule, catch up on anything that was skipped over summer, and plan for winter.
Winter: the occasional freeze
North Texas doesn't get long winters, but it does get freezing nights and the occasional ice storm.
- Washing below freezing is a bad idea: water freezes on vehicles, door seals and the pavement, and a wet yard can turn into an ice rink.
- We don't wash below freezing. Visits that land on a freezing day are rescheduled.
- Road treatment and slush can leave residue on lower panels and undercarriages after winter weather, so a wash once temperatures recover is a good idea.
A simple seasonal plan
| Season | Main problem | Wash adjustment |
|---|---|---|
| Spring | Pollen, then storms | Extra light washes for lots and light fleets; wash after rain |
| Late spring to early summer | Storms and mud | Heavy-mud washes for construction fleets during wet stretches |
| Summer | Heat, bugs | Night washes, front-end attention, spot-free rinse |
| Fall | Mild, some rain | Reset the schedule |
| Winter | Freezing days | Reschedule freezing days; wash after winter weather |
Let the schedule handle it
The easiest way to handle all of this is a recurring schedule that adjusts to the weather, so you don't have to think about it.
