Understanding Rust on Cars
Rust forms when metal reacts with oxygen and moisture. Road salt, scratches, and prolonged exposure to wet or humid conditions can speed up rust formation on cars.
Rust can weaken the metal, reduce your car’s resale value, and cause aesthetic damage if not handled early.

Step-by-Step Guide to Remove Rust
Follow these steps to remove rust from your car effectively:
1: Identify the Rusted Area
Begin by thoroughly inspecting your car. Rust typically appears near wheel wells, door frames, and the underbody. Clean the area with soap and water to remove dirt and dust.
2: Sand the Rusted Surface
Using sandpaper, start with a coarse grit (around 80-100) to remove surface rust. Gradually move to a finer grit (200-320) to smoothen the surface and prep it for treatment.
3: Apply a Rust Remover
For deeper rust, apply a rust remover or a homemade solution like vinegar and baking soda (explained below).
Allow the product to sit on the rusted surface for 15-30 minutes, then scrub off any remaining rust with a wire brush.
4: Prime and Paint
Once all rust is removed, apply a primer to protect the metal. Let it dry, then apply touch-up paint to blend the repaired area with the rest of your car.
5: Final Inspection
Ensure all rust is removed. Buff the surface to achieve a clean finish and prevent future rust from forming.
