The Winter Washing Dilemma
Ontario drivers face a difficult choice in winter: let corrosive road salt sit on your vehicle (causing rust and paint damage), or wash it off and risk frozen doors, icy windows, and water damage from washing in freezing temperatures. The answer is: wash it, but do it right.
When to Wash in Winter
Temperature Guidelines
Wash when temperatures are above -5°C (23°F) to allow for safe drying. Ideal conditions: a sunny day above 0°C following a major salt event. Avoid washing when temperatures will drop significantly after washing — water trapped in door seams and locks will freeze.
After Major Salt Events
After significant snowfall (when salt trucks are out heavily), wash within 2-3 days. Salt accumulation is most damaging when it sits for extended periods.
Winter Washing Techniques
Touchless Wash Recommended
In winter, avoid brush-based automatic washes. Salt and grit on your paint acts as sandpaper when brushes push it across the surface. Touchless automatic washes or careful hand washing are safer.
Undercarriage Focus
The undercarriage is where salt does the most damage. Ensure any wash includes thorough undercarriage rinsing. Many self-serve washes have undercarriage spray options.
Quick Drying
After washing, dry the vehicle as thoroughly as possible. Pay special attention to door jambs, window seals, and lock mechanisms. A blast of warm air from your car's heater with windows cracked can help dry interior edges.
Preventing Frozen Doors and Locks
- Apply silicone-based lubricant to door seals before winter
- Spray lock cylinders with lock de-icer or WD-40
- After washing, open and close all doors several times to prevent seal freezing
- Park in a heated garage if possible after washing
