1. Salt Causes Rust — Fast
Road salt accelerates corrosion on exposed metal. If left untreated, it can:
Eat away at your undercarriage
Corrode brake lines and fuel lines
Permanently damage your frame or body panels
Rust can begin forming in as little as a few days after exposure, especially if the salt isn't washed off and moisture lingers.
2. It Damages Paint and Clear Coat
Salt sticks to your vehicle's exterior and, when combined with slush or dirt, acts like sandpaper. Over time, it weakens your paint, dulls the finish, and compromises your clear coat — which protects your car from UV and further corrosion.
3. Regular Washing Prevents Long-Term Damage
The best way to protect your vehicle:
Wash your car every 1–2 weeks during winter
Focus on undercarriage wash options (we offer them!)
Even if your car doesn’t look dirty, salt is still at work underneath.
Avoid washing at home when temperatures are below freezing — the water can freeze and cause damage
At Cape May Car Wash, we use heated water and a controlled environment, so you can safely wash your car even on cold days.
4. Local Tip: Cape May Conditions Make It Worse
In coastal towns like ours, road salt + sea air = double trouble. The extra humidity speeds up the corrosion process. That’s why Cape May drivers should be especially proactive.
Bottom Line
Washing off road salt is about more than looks — it’s essential maintenance.
Regular winter washes protect your investment, prevent rust, and keep your ride looking sharp year-round.
