6 Things to Do Before and After a Michigan Winter
Every spring, we see cars come in with salt-corroded paint, stained carpets from wet boots, and interiors that smell like a damp basement. All of it preventable. Here's what to do before winter hits and what to do the moment it's over.
Before Winter: 1. Get a Full Exterior Detail with Sealant
Wax alone won't survive a Michigan winter. A sealant application creates a harder, longer-lasting barrier against road salt, brine, and ice melt chemicals. We apply sealant as part of our complete detail. It lasts 3 to 4 months, which gets you through the worst of it. Going into winter with bare paint is asking for oxidation and corrosion.
Before Winter: 2. Protect Your Interior
Swap your floor mats for rubber all-weather mats. Fabric mats soak up salt water from boots and hold moisture against the carpet for months. Rubber mats contain the mess and you can dump them out. If your car has leather seats, a fresh application of leather conditioner before November keeps the material from drying out and cracking in cold, low-humidity air.
Before Winter: 3. Clean and Treat the Door Seals
Rubber door seals freeze to the frame in sub-zero temps. When you yank the door open, the seal tears. Apply silicone-based rubber conditioner to every door seal before the first freeze. Takes 5 minutes and prevents a $200 repair.
After Winter: 4. Get the Salt Off Immediately
Don't wait until April to wash your car. The moment temps consistently stay above freezing, get a thorough hand wash. Focus on wheel wells, rocker panels, and the underside of the bumpers where salt builds up heaviest. Every week you delay, that salt is eating metal and clear coat.
After Winter: 5. Deep Clean the Interior
Five months of wet boots, road salt tracked onto carpets, and windows sealed shut means your interior is holding moisture and bacteria you can't see. Carpets need extraction, not just vacuuming. Salt crystals embed in carpet fibers and continue absorbing moisture from the air. A full interior detail after winter removes all of it and eliminates that damp smell.
After Winter: 6. Clay Bar and Reseal the Paint
Winter leaves a layer of bonded contaminants on your paint that washing alone can't remove. A clay bar treatment pulls out embedded salt, brake dust, and industrial fallout. Follow it with a fresh sealant application and your paint is protected for the next several months. This is the single best thing you can do for your car's exterior after a Michigan winter.
