How to Clean Foggy Headlights: A Comprehensive Guide
When it comes to driving at night or in conditions of limited visibility, ensuring that your headlights are in optimal working order is crucial for safety. However, it's not just about checking for burned-out bulbs. Fogging of the headlight lenses can also affect their effectiveness. This article will explore what causes foggy headlights and provide a step-by-step guide on how to clean them effectively.
What are Foggy Headlights?
If you notice that the light emanating from your headlights is less clear and has a yellowish tinge, your vehicle may be suffering from foggy headlights. The reason for this fogginess is scientific. Most modern headlight lenses are made from polycarbonate plastic, which is more scratch-resistant and durable than glass lenses used in older cars. However, exposure to UV rays from the sun causes the outer layers of these lenses to degrade and break down over time. This degradation leads to the absorption of blue light from the bulbs, resulting in a less potent and yellowish light emission.
What Products to Use When Cleaning Headlights
To clean foggy headlights effectively, you can find various products specifically designed for headlight restoration at auto supply stores. Look for products labeled as "headlight restoration kits" or "headlight lens restoration." These kits provide a straightforward solution for cleaning foggy headlights. However, if you need an immediate solution, you can also use household items such as toothpaste, baking soda, or polishing compounds.
How to Clean Foggy Headlights: Step-by-Step Guide
Cleaning foggy headlights is a relatively simple process. Here are the steps you can follow to clean your vehicle's headlights effectively:
Clean the Surface of Debris
Before you begin the restoration process, ensure that the headlights' surface is free of dirt, particulate matter, dead bugs, and other debris. Spray a mild cleanser onto the headlights and gently wipe away any accumulated grime using a soft cloth or rag.
Towel Dry
After cleansing the headlights, use a dry towel or rag to wipe down the surface until it is completely moisture-free. This step helps prepare the headlights for the application of the headlight restorer.
Apply Headlight Restorer
Next, apply a generous amount of headlight restorer to the lenses. This can be a product from a headlight restoration kit, toothpaste, or a mixture of baking soda and water. If using baking soda, create a thick paste by mixing it with a small amount of water. Leave the restorer on the lenses for a few minutes, allowing it to dry slightly.
Remove Restorer with Brush
Using a soft-bristled brush, gently work the headlight restorer into the surface of the foggy headlights. Employ circular motions while scrubbing, being careful not to apply excessive pressure that could scratch or damage the plastic surface. As you brush, you should notice the yellowish or fogginess disappearing from the lens.
Clean off Excess Restorer
Once you have finished brushing, use a clean rag or towel to remove any residual restorer from the lens. If there are any stubborn, dried-on bits, spray them with clean water and then continue polishing until the lens is dry. This step ensures that the headlights are left clean and clear.
By following these steps, you should notice an immediate improvement in visibility and the brightness of your headlights.
