The best way to maintain a rust-free car is, of course, stopping rust before it can start. Here are some tips to prevent rust on your car:
- Cover your car with a plastic covering when not in use, and try to drive further away from other cars to avoid the pebbles that kick up.
- Wash your car approximately every two to three weeks, or once a week if there is a lot of salt on the roads or if you live near the ocean. Pay special attention to the wheel wells and the underside of your car.
- Wax your car every four months
- Keep the interior (especially the rug and upholstery) clean from spills that can start rust from the inside.
- If you chip the paint of your car and bare metal is exposed, clean promptly and apply touch-up paint.
- Always protect and keep the metal surface dry if possible.
- If you are spraying your car with a flammable substance, make sure your engine is cold and give the car some time to dry before turning it on again.
- If your car is seriously at risk for rust (i.e. very old or regularly exposed to salt), you may consider cleaning and spraying with an appropriate rust-preventing lubricant or repainting.
- Examine your car frequently for rust. It will show directly on metal surfaces, and will show a small bubble or blister on the painted areas.
