How to Fix Rust Spots in Cars

Most autos get rust stains at some point. As the car ages the rust-proof coating gradually wears away. This leaves the car susceptible to rusting. When the underlying metal of the auto is continuously exposed to the elements, rust forms. The rust can affect the car both internally and externally. Do-it-yourself rust removal is a part of car maintenance. There are a few DIY auto rust repair methods.

Things You'll Need

• Wire brush or scrubbing pad
• Mineral oil or WD-40
• Lime juice or lemon juice
• Borax
• Rust remover
• Gloves

Instructions

1. Scrub off the rust. Use a scrubbing pad or wire brush to remove the rust stains. Hardware stores sell wire brushes.

2. Apply a lubricant. Apply a lubricant to soak into the rust stains. Choices include mineral oil or WD-40 among others. Apply mineral oil with a scrubbing pad or spray on the WD-40. Let the lubricant soak in for 10 to 30 minutes. Then scrub off the rust with the wire brush or scrubbing pad. Wipe clean. This method is for rust that does not respond to scrubbing.

3. Create an abrasive mixture. Combine two parts borax with one part lime juice or lemon juice. Make a paste. Then apply the paste to the rust stains with a scrubbing pad. Leave on for 15 to 30 minutes. Scrub the rust off. Wipe the areas clean with a cloth. This method is useful for more stubborn rust stains.

4. Apply a rust remover. Buy a rust remover form a hardware store. Put on gloves before applying the remover. Apply it with a paper towel or scrubbing pad. Wait a few minutes. Then scrub off the rust. Wipe the area clean.The rust remover dissolves rust stains because it is made with strong acids like hydrochloric acid or oxalic acid. Use commercial rust removers for large and difficult rust stains
