If you’ve ever walked past your car in the middle of a Newfoundland winter and noticed a white, dusty film along the lower panels… that’s not snow. It’s road salt, and it’s your paint and metal’s worst enemy.
In Canada, road salt is a necessary evil. It keeps our roads safe, but it also speeds up rust, eats away at your undercarriage, and can leave lasting scars on your paint.
Think of it this way: every time chloride-rich salt kicks up against your vehicle, it doesn’t just rinse off. It clings, trapping moisture and accelerating rust and corrosion. The U.S. Transportation Research Board reports that road salt often damages not just paint and trim but also critical components like frames, brake lines, and fenders — even in southern Canadian regions.
The good news? With the right care and protection, you can fight back against salt damage and keep your vehicle looking (and driving) like new for years to come.
Here are the top 5 ways to protect your car from salt damage this winter—and yes, they actually work.
1. Get an Undercarriage Wash Regularly
Salt damage starts where you can’t see it: underneath your vehicle. The undercarriage is one of the first areas to corrode, especially in our wet, salty winters.
A proper undercarriage wash flushes out all the salt buildup in wheel wells, frame rails, and suspension components, spots you’ll never reach with a garden hose.
At Swoosh Autodetailing, our undercarriage wash service goes beyond a quick rinse; we use specialized pressure washing techniques to get into every crevice where salt loves to hide.
Pro Tip: Aim for an undercarriage wash every 2–3 weeks during peak winter conditions.
2. Apply Ceramic Coating Before Winter Hits
Think of ceramic coating as a shield for your car’s paint. Unlike wax, which wears off quickly in the cold, ceramic coating bonds with your paint to create a hydrophobic, chemical-resistant layer.
This makes it harder for salt, grime, and moisture to stick and easier for you to wash them away before they do damage.
At Swoosh Autodetailing, our 5-year ceramic coating adds years of protection and a deep, glossy finish that makes winter cleanup effortless.
Pro Tip: The best time to get ceramic coating in Newfoundland is fall, before the first salt truck hits the road.
3. Keep Up with Winter Washes
Many drivers avoid washing their cars in the winter because they figure, “It’s just going to get dirty again tomorrow.”
Here’s the thing: salt damage doesn’t care if your car is clean or not; it starts working the second it lands on your vehicle.
A regular winter wash schedule prevents salt from sitting long enough to do harm.
Ideal Winter Wash Frequency:
City driving: Every 10–14 days.
Highway driving: Every 7–10 days (more salt exposure).
Even a basic wash helps, but a decontamination wash with clay bar treatment will ensure no micro-particles are left behind.
4. Protect Your Wheels & Rims
Your wheels face a constant blast of slush, salt, and grime. Over time, this not only dulls the finish but can also cause pitting and corrosion.
Wheel coatings or high-quality sealants create a barrier that makes brake dust and salt far easier to clean off. We also recommend avoiding acidic wheel cleaners in winter, as they can strip protective layers.
Pro Tip: If you have high-end rims, coating them is one of the best investments you can make.
5. Don’t Forget the Interior
Salt damage isn’t just a paint problem—it creeps inside too. The same salt that melts snow on roads ends up staining and damaging your carpets and mats when it’s tracked in on your boots.
Over time, salt can harden fabric, break down carpet fibers, and even cause rust on floor pans if moisture seeps through.
A winter interior detail with deep carpet extraction removes these deposits and keeps your cabin looking and smelling fresh.
Final Word: Winter Doesn’t Have to Destroy Your Car
Here in Newfoundland, we can’t escape road salt, but we can fight back against the damage it causes.
With a proactive maintenance routine that includes undercarriage washes, ceramic coating, regular winter washes, wheel protection, and interior care, you can keep your vehicle looking showroom-ready long after winter ends.
