The headlight covers on many cars are made of glass, a clear surface that allows the headlight bulbs to shine brightly, giving you as much lighting as possible during road travel in inclement weather or late evening hours. To both keep the headlights attractive and allow the headlights to emit the brightest possible light display, you must clean the headlights regularly. This can be done with some inexpensive ingredients that are probably already in your home.
Pour a cleaning solution into a spray bottle by combining equal parts of vinegar and water, adding a squirt of liquid dish soap. The vinegar and soap will cut through residue and clean the glass without leaving a film behind.
Spray the cleaning solution directly onto the glass headlights and scrub in small circular movements with a nylon scrub brush.
Squirt a dollop of toothpaste onto the headlights. Scrub the toothpaste into the headlights with the nylon scrub brush.
Soak a cleaning rag with hot water and wipe over the headlights to remove the toothpaste.
Dry the headlights with a fresh cleaning cloth.
