Winter can be tough on your vehicle, with moisture, road salt, and grime creating the perfect conditions for rust to develop. Protecting your car during the colder months is crucial for preserving its value and longevity. Here are ten essential steps to keep rust at bay this winter.

1. Wash Your Car Regularly

Clean your vehicle every 10 to 14 days throughout winter to remove salt and grime, which accelerate rust formation. Pay special attention to the undercarriage, where salt builds up the most. Consider using specialist products such as Rustbuster Chlor-X for thorough cleaning.

2. Apply a Protective Undercoating

An oil-based undercoating like Fluid Film, Corrolan, or Dinitrol creates a strong barrier against moisture and salt. Applying this treatment to your car’s underbody helps prevent rust before it starts. Reapply as needed—typically every six months.

3. Keep Your Car Covered

Where possible, park in a garage or use a Car-Zone car cover to protect your vehicle from snow, ice, and road salt. Keeping your car sheltered reduces exposure to winter elements and minimises rust risk.

4. Inspect and Touch Up Paintwork

Regularly check your car for paint chips and scratches. Even small chips can expose the metal underneath, allowing moisture and salt to trigger rust. Touch up any damage promptly with the correct paint to prevent further issues.

5. Use Rubber Floor Mats

Fabric mats absorb moisture, which can lead to rust on the floor panels. During winter, switch to rubber floor mats to prevent water from seeping into the car’s flooring.

6. Avoid Driving Through Deep Snow and Puddles

Deep snow and standing water can splash salt and moisture onto your vehicle’s undercarriage, increasing the likelihood of rust. Try to avoid driving through puddles and compacted snowbanks whenever possible.

7. Keep Your Car’s Interior Dry

Moisture inside the car can cause rust from within, particularly on the floorboards. Prevent this by:

• Brushing snow off your shoes before entering.
• Using moisture-absorbing products to keep humidity levels low inside the vehicle.
• Checking for leaks that could allow water inside.

8. Apply Wax for Extra Protection

A fresh coat of wax acts as a shield against moisture and road salt. Apply wax before winter begins and consider reapplying mid-season for continued protection.

9. Check and Clear Drainage Areas

Blocked drainage holes in your doors, bonnet, and boot can cause water build-up, leading to rust in hidden areas. Regularly inspect and clear any debris from these drainage points.

10. Schedule Professional Rustproofing

For maximum protection, consider professional rustproofing services before winter arrives. Treatments such as Rustbuster’s Hot Fog method provide comprehensive rust prevention, ensuring your car stays protected throughout the harsh winter months.
