Rinse the underbody after every significant winter storm, keep the paint sealed, and have the brake lines, fuel lines, exhaust and suspension hardware inspected before and after the season. For a Range Rover, Defender or Discovery, that routine, started before the first salt goes down on Dayton roads, keeps salt from sitting on the parts Ohio winters corrode first.
Book a pre-winter inspection See the season routineEvery winter, state and local crews put hundreds of thousands of tons of salt and brine on Ohio roads, including I-75, I-70 and US-35, the routes Miami Valley drivers use daily. The figures below explain why a Land Rover garaged in Dayton needs a deliberate winter routine.
Latest published figures, as of October 2026
Sources: Spectrum News on ODOT winter operations; AAA on road de-icers and rust damage.
Salt does its damage underneath, where it is hard to see. AAA identifies fuel tanks, brake lines and exhaust systems as the components most exposed to rust from de-icers, and it notes that liquid de-icers such as the brine used to pre-treat roads are even more corrosive than traditional rock salt.
| Area | What salt does | What to do |
|---|---|---|
| Brake lines | Corrodes exposed lines and fittings, a safety-critical rust point | Inspect before and after winter; rinse the underbody through the season |
| Fuel tank and lines | Brine collects on the tank straps and along the lines | Underbody rinse after storms; inspect at spring service |
| Exhaust system | Heat cycles plus salt speed corrosion of hangers and joints | Listen for new rattles; have hangers checked at inspection |
| Suspension and subframe hardware | Salt packs into brackets, bolts and suspension components | Rinse wheel wells; ask for an air suspension check on air-suspension models |
| Paint chips and wheels | Stone chips expose bare metal; salt sits on wheel finishes | Seal paint before winter; touch up chips; wash wheels |
Every new Land Rover's six-year, unlimited-mileage corrosion perforation warranty covers rust-through of the body, not surface rust or chip damage, and brake, fuel and exhaust components rely entirely on the owner's winter routine.
Wash the vehicle thoroughly, apply a wax or paint sealant, and touch up stone chips while temperatures still allow it. Book an inspection so a technician can look at brake lines, the exhaust, the underbody and the suspension, including air suspension where fitted, before salt goes down.
AAA recommends washing after every significant winter storm, with particular attention to the undercarriage. Choose a wash with an underbody spray, rinse the wheel wells, and pick a day above freezing so door seals and locks dry instead of freezing.
Salt tracked in on boots dries into white residue on carpet. Rubber floor mats contain it, and vacuuming the residue out regularly keeps it from working into the carpet fibers.
Give the underbody a thorough final wash in spring and have it inspected at the next scheduled service, while any corrosion is still surface-level and inexpensive to treat.
A pre-winter visit is the cheapest point to catch salt damage, because anything found now is treated before months of brine exposure. Ask the technician to look at each of these and note the condition on the repair order, so the spring inspection has a baseline to compare against.
Every new Land Rover carries a six-year, unlimited-mileage corrosion perforation warranty, separate from the 4-year, 50,000-mile New Vehicle Limited Warranty. It addresses rust-through of body panels. The warranty is for rust-through, not surface rust that starts at stone chips or paint damage, so sealing chips promptly is the owner's job.

Undercoating is an optional extra, not a substitute for washing and inspection. If you are considering one, have the underbody inspected first so the coating doesn't seal in corrosion that has already started, and keep the paperwork with the vehicle's service records.
Land Rover Dayton's service team can inspect brake lines, the exhaust, the underbody and the suspension before the season starts, and again in spring. Owners still choosing a winter vehicle can compare capability across the lineup in our Ohio luxury SUV buyer's guide, and Range Rover owners can see how winter care fits a yearly budget in our Range Rover maintenance cost benchmarks.

Yes. AAA notes that liquid de-icers are faster and more effective on roads but even more corrosive than traditional rock salt, which makes underbody rinses more important on pre-treated roads.
