WD 40 is a multi-used product that has the feature of anti-rust, dehumidification, rust removal, lubrication, cleaning, conductivity. It is said that the WD 40 can serve as a headlight lens restorer together with other real lubricants, which effectively defog headlights. In fact, it can quickly defog your headlights, but you shouldn’t let using WD 40 become a habit for your headlight restoration. If you use it repeatedly, the oil will leak into your headlight bulb, causing it to burn. In addition, the defogging effect can only be maintained for one day or two days. For a more durable solution, It’s better to use a headlight restoration kit.
