Learn How to Easily Remove Rust with a Rust Neutralizer on Your Car

Using a rust neutralizer is an easy way to protect many household items made of iron and steel indoors and out, as well as protecting the finish of your car. These products come in aerosol cans and brush-on types, and work by chemically reacting with rust and creating a non-rusting surface that is good for painting.

For cars, the best option is to apply the rust neutralizer in a spray chamber with specially designed equipment. Spray-on neutralizers are most popular for do-it-yourselfers and homeowners and are best for mild surface rust. Before you apply the rust neutralizer, it is important to prepare the surface first by removing all loose rust with sandpaper, steel wool, or a wire brush. Cleaning the area from dirt, grease, and oil is also important, as this will help the rust neutralizer work better.

Once you have prepped the surface, spray or brush the neutralizer on following the manufacturer’s instructions and allow it to dry fully. However, make sure to never apply rust neutralizer directly in direct sunlight, as it will not dry properly and won’t create a proper bond. Also, never apply the rust neutralizer to surfaces with active water beneath them, as this will not work. Fully apply the neutralizer, allow it to dry, and then finish with a coat of oil-based or lacquer-based paint. Using latex paint is not recommended.

After the paint is dry, avoid sanding the treated area. This can break the seal and bond between the rust neutralizer and paint and allow for moisture to build up. Rust neutralizers also should not be used in places where there is heavy salt spray from oceans, or immense amounts of snow or ice. Similarly, refrain from using them in oxygen-rich or pure oxygen areas as well.

Applying a rust neutralizer can help strengthen and protect metal surfaces both indoors and outdoors, and can help protect your car from rust damage. Make sure to follow the instructions for the product, be mindful of its use in certain areas, and finish it with oil-based or lacquer-based paints for best results.
