What an Alberta Winter Leaves on Your Car

By the time the snow finally lets go around High River and Okotoks, most trucks and SUVs in the Foothills are carrying a winter's worth of grit. It doesn't look like much from across the driveway. Up close, there's a grey film on the lower doors, white crust in the wheel wells, and a stiff, gritty layer on the floor mats that crunches when you step on it. That's the leftover from months of sand, slush and road treatments, and it keeps working on your vehicle long after the roads dry out.

What winter driving leaves behind

Three things ride home with you every winter. The first is sand and fine gravel, which gets thrown against the lower panels, bumpers and the leading edge of the hood. Those tiny impacts leave chips and a haze of micro-scratches that you only notice once the sun comes out. The second is road salt and de-icing brine. The third is a film of traffic grime, oil mist and brake dust that bonds to paint and wheels in the cold and doesn't rinse off with a garden hose.

Why salt does damage after the snow is gone

Salt on its own isn't dramatic. The trouble is that it holds moisture against metal and keeps the surface damp longer than it would be otherwise, which speeds up rust on anything exposed: chipped paint, bare fasteners, brake hardware, the lower edges of doors. Every stone chip from the winter is a small opening, and salty slush sits in it for months. Spring is the right time to deal with it, before warm weather and the odd wet May snowfall give that moisture something to do.

Salt also dulls clear coat. A film of dried chloride and road grime scatters light, so a dark vehicle that looked deep and glossy in October looks tired and flat by April. That isn't the paint failing. It's a layer sitting on top of it, and a decontamination wash can take it off.

Wheels, wheel wells and carpets

Wheels take the worst of it. Brake dust is made of tiny iron particles, and when it mixes with wet salt it bakes onto the wheel face and into the barrel behind the spokes. If you've ever pulled a wheel in spring and found a crust behind it, you've seen exactly what we mean.

Inside, the carpets tell the same story. Slush melts off your boots and the salt in it stays behind as white tide lines in the fibre, mostly on the driver's side and in the rear footwells. Rubber mats help, but water still creeps around the edges. Damp carpet that never fully dries can also leave a stale, musty smell in a closed cab, which is why a spring interior is as much about the air in the vehicle as how it looks.

What a spring detail actually removes

A proper spring detail works in a set order, and each step does a job the one before can't. The wheel faces and tires get brushed. On the Exterior Deep Clean package the wheel barrels and calipers are brushed too. An iron remover goes on the paint and wheels and reacts with embedded iron particles, which is why you'll see it turn purple and run. Then the vehicle is washed, and a clay treatment lifts whatever is still bonded to the paint, the grit that makes a clean panel feel rough under your hand.

From there it's a choice of finish. Wash, Clay & Seal, from $149 and about 2 hours, finishes with a ceramic wax and tire dressing. Exterior Deep Clean, from $269 and 3 hours, adds the iron remover, decontaminated wheels, brushed barrels and calipers, and a water spot remover. Polish & Protect, from $399 and 4 hours, adds a single-stage paint enhancement and a ceramic paint sealant with 6 months of protection, which carries a vehicle from spring clear through the summer.

Inside, Interior Refresh, from $229 and 2 hours 30 minutes, uses steam cleaning, a blowout, a full vacuum and washed floor mats, which is the package that deals with salt-stained mats and the grime in the crevices. If the carpets have tide lines, stains or that damp smell, Interior Reset, from $299 and 3 hours, adds a three-step shampoo and spot treatment for stains. The trunk isn't included in any of the interior packages, so mention it when you book if that's where the winter gear lives.

Choosing what your vehicle needs

Prices scale by vehicle size: coupe or sedan, SUV or truck, and full-size or three-row. If you've got a truck that worked all winter on gravel roads, start with the Exterior Deep Clean. If the paint is already in good shape and you mostly want it clean and protected, Wash, Clay & Seal is plenty. Full Detail Express, from $299 and about 4 hours, pairs a Quick Interior with Wash, Clay & Seal. Full Detail Plus, from $449 and 6 hours, pairs Interior Refresh with Exterior Deep Clean, and it's the one most people want after a hard winter.
