Abstract: A headlight lens cleaning tool includes an internal cleaning pad and an external guider. The internal cleaning pad is configured to clean the interior surface of a sealed beam headlight lens without requiring removal of the headlight assembly from a vehicle or disassembly of the headlight assembly. The internal cleaning pad can be inserted into the headlight assembly by way of a headlamp bulb socket opening, and can include a core that is capable of being attracted by a magnetic field and a pliable covering to wipe clean the interior surface of the headlight lens. The external guider can include a permanent magnet, and can be placed against the exterior surface of the headlight lens in order to retain the cleaning pad against the interior surface and move the cleaning pad about the interior surface of the headlight lens to clean the interior surface of the headlight lens.
