How to Repair Rust on a 356 Porsche
- 1). Scour off the rust. At the first sign of rust, take steps to remove it so it doesn't spread. Use objects that have an abrasive texture such as steel, a scrubbing pad or sandpaper, suggests the article "Removing Rust from Tools" at the Thrifty Fun website. Rub the pad or steel wool on the 356's rust stains until it disappears. Some elbow grease may be required.
- 2). Use mineral oil. Allow the oil to seep into the rust, then scrub off using steel wool or a scrubbing pad.
- 3). Try lemon juice. For home remedies, lemon juice is known to help in removing rust stains. Lemon juice has citric acid that breaks down rust. The article "How to Create a Homemade Rust Remover" on the Edubook website suggests adding borax for its abrasive action. Add 1 teaspoon of lemon juice to a small amount of borax to make a paste. Apply the paste to the the 356's rust. Let it stand for a few minutes. Then clean away with a scrubbing pad.
- 4). Use naval jelly. Naval jelly is a well-known rust remover. The Thrifty Fun website suggests this product because it contains phosphoric acid in a gel form. The acid dissolves the rust. You can buy naval jelly in home-improvement and do-it-yourself centers. Because of the acid content, be certain to follow the directions carefully.
- 5). Use commercial rust removers. There are many commercial rust removers on the market. These substances contain strong acids like phosphoric acid, oxalic acid and hydrochloric acid that dissolve rust. Follow the directions precisely to maintain safety. Although toxic, these substances are very effective in moving rust from cars.
