Weathering the Winter: Protecting Your Fleet from Snow and Salt Damage

As temperatures drop and snow begins to fall, a hidden threat emerges for fleet operators: road salt. While vital for road safety, salt is a corrosive agent that can wreak havoc on commercial vehicles, leading to rust, mechanical failure, and costly downtime. Protecting your assets calls for a proactive approach.

The best defence begins before the first snowflake. A pre-winter maintenance plan is essential.

The undercarriage and chassis are the most vulnerable areas. Inspect for existing rust or damage and apply a high-quality, protective undercoating. Waxy or oily barrier films are highly effective at sealing out moisture and salt.

Apply a durable wax or sealant to painted surfaces. This protective layer repels water and salt, preventing paint damage and making subsequent cleaning easier.

Ensure all fluids, especially engine coolant and windshield washer fluid, are winter rated. Check tyre pressure and tread depth and consider using winter-specific tyres for better traction and safety.

Once winter arrives, the fight against corrosion becomes a daily battle and the single most effective tactic is a quick, daily rinse of the undercarriage.  

A high-pressure wash at the end of a shift, even if it’s just for five minutes, can remove enough salt and slush to prevent it from causing damage overnight.

If possible, park vehicles in a garage or under carports to prevent snow and ice buildup. This minimises the time moisture spends in contact with the vehicle's surfaces.

By implementing these straightforward, proactive strategies, fleet managers can significantly reduce the corrosive effects of the winter weather, safeguarding their investment and ensuring the fleet stays on the move throughout the coldest months.
