How to Fix a Rusty Car Door

Fix collecting rust before it coats your entire car door.

You might notice patches of rust on your car door after removing it from long-term storage, while detailing it at home or when performing a cosmetic inspection. Rust forms when oxygen and moisture react with most types of metal. If left untreated, rust can spread quickly and degrade the metal completely, resulting in chipping, flaking and holes. To avoid expensive repair procedures or door replacement, fix your rust problem while you can. Most minor cases of rust can be removed with household materials.

Things You'll Need

• Scrub brush
• Dish soap
• Microfiber cloths
• Steel wool (#0000)
• Oil lubricant
• Automotive wax
• Polishing cloth

Instructions

1. Using a scrub brush and a solution of warm water and dish soap, scrub the metal of your car door. Wipe the door dry with a clean, microfiber cloth.

2. Saturate a #0000 steel wool pad with the oil-based lubricant. Rub the rusted area of the car door using a circular motion. For stubborn rust patches, apply firm pressure.

3. Check your progress regularly, applying more lubricant or switching to a fresh pad of steel wool, as needed. Wipe away excess oil residue with a damp cloth.

4. Spread an even layer of automotive wax over the cleaned area of the car door. Allow the wax to dry for the time suggested on the container, or until it is powdery in texture.

5. Buff off the wax using a polishing cloth and a rapid circular motion. Repeat Steps 4 and 5 every several months to protect your car door from rust.

Tips & Warnings

• Wipe the outside of your vehicle dry after exposure to rain, mud or other moisture to prevent the onset of rust.

• If rust has escalated to the point of chipping or flaking, consult a professional auto body service for advice or repair.

• Avoid using abrasive rust removal products on painted metal, as they may damage the coat.
