Why is it important to dry vehicles after washing?

Drying vehicles after washing is crucial primarily because it helps prevent water spots and streaks on the paint. When water evaporates slowly from the surface of a vehicle, it can leave mineral deposits that create unsightly spots. These water spots can bond with the paint and become very difficult to remove if left untreated, potentially leading to more extensive detailing work later on.

Additionally, drying the vehicle promptly ensures that any remaining dirt or residues are also wiped away, leading to a cleaner finish. It also prevents the formation of streaks that can diminish the visual appeal of the car. While drying may aid in the application of protective wax and contribute to a polished look, the most critical reason is to protect the paint surface from damage and maintain the vehicle's aesthetic quality.
