By March, most Chicago cars are wearing a chalky film of road salt. It’s more than cosmetic — salt speeds up rust, especially where you can’t see it. Here’s how to get it off and keep it off.
Start with the undercarriage
The underside of your car — frame rails, brake lines, wheel wells — takes the worst of the salt and is the hardest to reach at home. This is where an undercarriage rinse earns its keep. Nappa’s Deluxe and Extreme washes include an undercarriage wash to flush salt from underneath.
Don’t forget the wheel wells and wheels
Salt and slush pack into wheel wells and cake onto rims. A machine rim cleaner and high-pressure rinse lift far more of it than a driveway hose.
Rinse the body thoroughly, then protect
A high-pressure rinse breaks the salt film off the paint; a wax or sealant step then adds a barrier so the next round of salt has a harder time sticking.
Wash more often during salt season
The single best habit is frequency. Through the worst of winter, a wash every week or two keeps salt from sitting long enough to do damage. If you’re washing that often, a monthly membership is usually the cheaper path — and it’s valid at every Nappa location.
None of this requires an appointment. Drive up, choose a wash with an undercarriage rinse, ride through the tunnel, and hit the free vacuums on the way out.
