How to prevent rust in an Audi A2?

I recently noticed some rust spots on my Audi A2. What can I do to prevent further rusting?

Regularly wash your car and remove any road salt and grime that can cause rust. Also, make sure to keep your car waxed to protect the paint from rust-causing elements.

Inspect your car frequently for any signs of rust and address them immediately. Don't let small rust spots turn into costly repairs.

Keep your car in a garage or use a car cover to protect it from harsh weather conditions that can accelerate rusting.
