If you only need a quick rinse to remove dust or light dirt, a DIY wash or touchless machine might be fine. But if you care about protecting your car’s finish, maintaining resale value, or simply don’t have time, a professional car wash or detailing service is worth it.
This is especially true in Canada, where winter roads are treated with salt that can accelerate rust and corrosion. A thorough cleaning and undercarriage wash from a professional service can prevent long-term damage.
