Salt spray settles underneath the vehicle long before it becomes obvious on the paint. Wheel arches, lower doors and seams carry the highest risk through winter.

The longer salt and moisture sit together, the more chance they have to work into vulnerable areas. A regular wash routine keeps the buildup from becoming a repair.

Wash before the buildup hardens

A regular underbody rinse after wet, salted journeys removes the film while it is still loose. Leave it for weeks and moisture keeps working in the places you rarely see.

Winter protection is less about one deep clean and more about keeping salt from settling in.

The cold-weather routine

• Rinse arches and lower panels after salted roads

• Use a gentle wash to remove road film

• Pay extra attention to seams and door shuts

• Book a fuller clean after long winter trips

The practical routine is simple: rinse the arches often, wash the full vehicle regularly and give the lower panels extra attention after every cold spell.

At the end of winter

A detailed clean is the right reset when the weather turns. It removes the residue left behind by months of wet roads and cold starts.
