Road-salt car wash in Chicago
Chicago winters cake your car in salt and slush. Here’s why the undercarriage matters most — and how to stay ahead of rust all season.
Why road salt is hard on your car
Chicago spreads salt to keep winter roads safe — but that same salt clings to your car’s undercarriage, wheel wells, and lower panels. Left there, it speeds up rust and corrosion in exactly the places you can’t easily see or reach at home.
The undercarriage is the priority
The underside of your vehicle takes the worst of it. Nappa’s Deluxe and Extreme washes include an undercarriage rinse that flushes salt and slush from underneath — the single most useful step in salt season.
Wash more often when it counts
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, an unlimited membership is usually the cheaper path — and it’s valid at all four Chicago locations.
This guide is general car-care information, not a warranty or guarantee against rust or vehicle damage.
