Toothpaste for car headlights: Quick fix or temporary shine?

Home remedies like toothpaste can temporarily clear foggy headlights by gently polishing away oxidation. However, scientific research reveals this effect is short-lived, lasting only weeks. Unlike professional restoration, toothpaste offers no UV protection, leading to rapid re-hazing. For lasting clarity and safety, professional treatments or DIY methods incorporating UV sealants are recommended.
