Winter driving comes with its challenges, and one major concern is road salt buildup on vehicles. While road salt helps melt ice and improve traction. It can cause severe damage to your car’s undercarriage, paint, and metal components. Find out how to remove road salt from car and prevent rust, it is that time of year!
If left untreated, it leads to rust and corrosion, significantly reducing your vehicle’s lifespan. Learning how to remove road salt from your car properly and prevent rust will keep your vehicle in top condition through the colder months. The best approach is to remove road salt from your car as soon as possible to prevent long-term damage.
Why Road Salt is Harmful to Your Car
Road salt is highly corrosive and accelerates rust formation on exposed metal surfaces. When salt mixes with moisture, it creates an electrolyte that speeds up oxidation. This reaction weakens your vehicle’s frame and can lead to costly repairs. The most vulnerable areas include:
- Undercarriage and wheel wells
- Brake lines and suspension components
- Exhaust system and fuel lines
- Door sills and lower body panels
Regular cleaning and protective measures will help you combat the harmful effects of road salt and keep your car rust-free. That’s why it’s crucial to remove road salt from car regularly during winter.
Best Time to Remove Road Salt from Car
Washing your car at the right time prevents damage. Avoid washing when temperatures are below freezing, as water can freeze on your vehicle and create more problems. The best times to wash include:
- On warmer winter days (above 35°F/2°C)
- After snowstorms when roads are heavily salted
- Every two weeks if driving frequently in winter conditions
Consistent cleaning will reduce salt buildup and prevent long-term corrosion. Make it a habit to remove road salt from car as part of your winter vehicle maintenance.
Step-by-Step Guide to Removing Road Salt from Your Car
1. Gather the Right Cleaning Supplies
Before you start, make sure you have the proper tools and products. You will need:
- A high-pressure hose or pressure washer
- Two buckets (one for soapy water, one for tires and rims)
- A car wash soap designed for removing salt
- A microfiber mitt or cloth and a soft-bristle brush for the wheels
- Undercarriage cleaning attachment (optional)
- A drying towel or chamois
- Salt Off Protector Kit W/Ptef (highly recommended for neutralizing road salt)
2. Rinse Off Loose Dirt and Salt
Start by spraying your car with a high-pressure hose. Focus on the undercarriage, wheel wells, and lower body panels where salt accumulates the most. Use a back-and-forth motion to ensure all loose debris washes away. Removing road salt from your car with a strong rinse helps minimize corrosion before deeper cleaning.
3. Wash with a Salt-Removing Solution
Mix car wash soap with warm water in a bucket. Dip your wash mitt or brush into the solution and scrub all exterior surfaces. Pay extra attention to areas near the wheels and undercarriage. If using an undercarriage cleaner, attach it to your hose and spray underneath to reach hidden salt deposits.
For the best results, use Salt Off Protector Kit W/Ptef. This product effectively neutralizes road salt, preventing it from causing further damage. Simply apply as directed to dissolve salt residues and protect your vehicle’s surfaces. It is one of the most effective ways to remove road salt from car and ensure it doesn’t cause rust.
Wash you wheels and tires with a separate bucket and brush. It is always good to use a good wheel cleaner that will remove road salts. Super Clean All Wheel Cleaner not only cuts the grease and brake dust from wheels effortlessly, but is also removes road salts.
4. Rinse Thoroughly
Use clean water to rinse off all soap and salt residue. Ensure no cleaning solution remains, as it can cause streaks or further damage if left on the paint.
5. Dry the Vehicle Properly
After rinsing, dry your car with a microfiber towel or chamois to prevent water spots. Drying also reduces the chances of moisture lingering, which can lead to rust formation.
6. Apply a Protective Wax or Sealant
Once your car is clean and dry, apply a layer of wax or sealant. This protective barrier helps repel salt and moisture, making future cleanings easier and reducing corrosion risks. This additional step enhances the benefits of removing road salt from your car by offering long-term protection.
Additional Tips for Preventing Rust from Road Salt
Keeping your car free from rust requires more than just cleaning. Here are additional steps to protect your vehicle:
Use a Rust-Proofing Spray
Applying a rust-proofing spray to exposed metal areas adds an extra layer of protection. Focus on the undercarriage, door edges, and wheel wells.
One of the best protectants is RustKote Rust Fighter. It is an aerosol that provides corrosion protection, neutralizes road salt and lifts moisture. It works great in wheel wells, on rear quarter panels, rocker panels and frame and chassis.
Once all your panels are dry from using RustKote, apply a coat of Mothers California Gold Ceramic Spray Wax. The spray ceramics are great for door jams and hard to get to places. The ceramic wax will help with road salt and grime form rusting out hard to get to areas.
Regularly Inspect Your Car for Rust
Check your vehicle frequently for any early signs of rust. If you notice bubbling paint or reddish-brown spots, address them immediately before they spread.
Park in a Garage or Covered Area
If possible, park your car in a garage or covered area to reduce exposure to moisture and salt. If using a garage, ensure proper ventilation to prevent trapped moisture from accelerating rust formation.
Avoid Driving Through Deep Snow and Puddles
Snow and slush often contain high concentrations of road salt. Avoid driving through deep snowbanks or puddles that can splash saltwater onto your car’s undercarriage.
Schedule Professional Undercoating Treatments
Many auto shops offer professional undercoating treatments that create a barrier against moisture and salt. Consider getting this done before winter begins.
When to Visit a Professional for Salt Removal
While regular home washes are effective, there are times when professional services are necessary. If you notice excessive salt buildup, stubborn rust spots, or difficulty reaching certain areas, visit a car wash that offers undercarriage cleaning. Some detailing shops also provide specialized treatments to neutralize road salt.
