What is the best way to prevent rust on an Audi A6?

I recently purchased an Audi A6 and want to keep it in top condition. What steps can I take to prevent rust on my vehicle?

Regularly wash and wax your car to protect the paint and metal from water and oxygen that can cause rust. Also, make sure to clean any salt or dirt buildup from the undercarriage to prevent corrosion.

Another way to prevent rust is to apply a rust inhibitor or rust-proofing spray to areas that are prone to rust, such as the wheel wells and door jambs. This will create a barrier between the metal and moisture, preventing rust from forming.
