How to Protect Your Vehicle from Salt & Road Corrosion This Winter in Maryland

When winter hits Maryland, road crews work diligently to keep drivers safe by applying salt and de-icing materials. While that helps prevent accidents, it also exposes your vehicle to one of its worst enemies: corrosion. Over time, salt buildup can cause rust that damages your car’s body, brakes, and undercarriage—leading to expensive repairs down the line.

At Advanced Automotive Repair in Frederick, MD, we want to help you protect your investment and keep your car running strong all season long. 

Here are five ways you can minimize salt-related damage this winter.

1. Wash Your Vehicle Regularly—Especially the Undercarriage

Road salt tends to accumulate underneath your vehicle, where moisture and metal meet—a perfect environment for rust to develop.

• Visit a car wash with undercarriage cleaning at least every two weeks during winter.
  
• After a snowstorm or heavy salting, rinse off salt as soon as temperatures rise above freezing.
  
• Don’t forget areas like wheel wells, bumpers, and the lower side panels.

If you prefer to wash at home, use warm water and a gentle detergent designed for cars. Avoid high-pressure settings that could strip off paint or protective coatings.

2. Apply a Protective Wax or Undercoating

A quality wax or undercoating creates a barrier between your car’s metal and corrosive salt.

• Wax your car before the first snowfall for best results.
  
• Consider a professional undercoating service or a rust inhibitor for long-term protection, especially if you frequently drive or park outdoors.

Our technicians at Advanced Automotive Repair can recommend products and services to help safeguard your vehicle’s most vulnerable parts.

3. Keep Up with Regular Maintenance

Corrosion often attacks areas that are already compromised, such as chipped paint, loose seals, or worn brake components.

• Inspect your brake lines, exhaust system, and suspension for early signs of rust or wear.
  
• Make sure the drain holes in doors and rocker panels aren’t clogged so water can escape.
  
• Check your tires and alignment after harsh winter driving to prevent uneven wear.
  

A mid-winter inspection at Advanced Automotive Repair in Frederick can catch these issues early before they appear unannounced.

4. Avoid Parking on Snow or in Puddles

It might seem harmless, but parking on snow or wet surfaces traps moisture and salt against your undercarriage for extended periods. Whenever possible:

• Park indoors or in a covered area.
  
• Brush snow away from around your tires before leaving your vehicle for long periods.

If you must park outside, consider laying down a tarp or car mat beneath the vehicle during icy conditions to minimize exposure to the elements.

5. Schedule a Post-Winter Inspection

Once spring arrives, it’s essential to have your vehicle checked for any lingering salt damage. Our ASE-certified technicians at Advanced Automotive Repair can:

• Inspect and clean your undercarriage.
  
• Check for brake and exhaust corrosion.
  
• Reapply protective coatings where needed.

We’ll help ensure your car looks great, performs reliably, and stays rust-free for years to come.
