Rust is every car owner’s nightmare. It not only spoils your vehicle’s appearance but also weakens its structure over time, leading to costly repairs. The good news? With the right car care products and a consistent maintenance routine, you can keep rust at bay and extend your car’s life.
In this guide, we’ll explain why rust forms, how to stop it before it starts, and which Salty Captain products are essential for long lasting protection.
Why Cars Rust in the First Place
Rust occurs when iron or steel reacts with oxygen and moisture, creating oxidation. Common causes include:
Salt exposure – from beach driving or coastal air.
Road grime and chemicals – especially in winter or rainy conditions.
Trapped moisture – in wheel wells, underbody, and hidden crevices.
Chips and scratches – exposing bare metal to the elements.
If you live near the coast or frequently go off-road, your car is at higher risk. That’s why a proactive rust prevention routine is critical.
Step 1: Regular Washing to Remove Corrosive Elements
The first defence against rust is keeping your car clean. Salt, mud, and dirt hold moisture, which accelerates corrosion.
- Use a Car Wash Detergent that’s tough on grime but gentle on paint.
- Adopt the two-bucket method to prevent scratching.
- Rinse under the car to flush out trapped salt and dirt.
For coastal drivers or 4WD owners, Salty Captain’s Captain’s Musket makes underbody and wheel well cleaning easy with its high-pressure foam application.
Step 2: Protect with the Right Coatings
Once your car is clean, apply a protective barrier to block moisture and contaminants.
Salty Captain’s Protection Products include hydrophobic sprays and UV protectants that shield your paint from water, salt, and sun damage.
Benefits of using a quality protective coating:
- Prevents water from clinging to surfaces.
- Reduces dirt build-up.
- Adds a glossy finish for a showroom look.
Step 3: Keep the Undercarriage Clean
Rust often starts underneath where you can’t see it. That’s why undercarriage maintenance is essential.
- Use 4WD Cleaning Tools or a chassis flusher to blast away salt and mud.
- Dry the underbody to prevent trapped moisture.
- Apply a rust inhibitor spray for long-term protection.
If you do regular beach runs, pairing Salty Captain’s Chassis Grenade with our Chassis Flush Solution is a must for deep cleaning.
Step 4: Address Paint Chips and Scratches Immediately
Exposed metal is a direct invitation for rust. Inspect your car regularly and:
- Touch up small paint chips.
- Polish and seal the surface after repairs.
- Avoid letting bare metal stay exposed for long periods.
A protective wax or sealant from our car care products range can help shield vulnerable areas.
Step 5: Interior Maintenance Matters Too
While interior care might not seem directly related to rust prevention, moisture build-up inside the cabin can lead to corrosion in hidden areas.
- Use our Interior Cleaner to keep surfaces dry and free from spills.
- Check for leaks around windows and doors.
- Remove wet floor mats and let them dry completely.
Extra Tips for Rust Prevention
- Avoid parking on grass or dirt – moisture rises from the ground.
- Store your car in a garage or use a breathable car cover.
- Inspect your vehicle after rain or beach trips for early signs of corrosion.
