WD-40 isn't just for fixing squeaky doors and rusty parts – it can also make cloudy headlights clear again. Over time, car headlights get foggy because of a layer of dirt and oxidation that builds up on them. Using WD-40 helps remove this cloudiness by breaking down this dirty layer. According to automotive expert Lauren Fix, "WD-40 can temporarily remove the hazy film on headlights, but it's important to note this is a short-term solution that might need to be repeated every few months." While this fix won't last forever, it's a quick and cheap way to help you see better when driving at night and keep your car safer. Let's learn how to use WD-40 on your headlights without getting it on your car's paint.
Dirty or Oxidized Headlights Reduce Visibility
While we often focus on keeping our car's exterior clean, it's easy to overlook the essential role that clear headlights play in our safety.
When our vehicle's headlights become foggy or oxidized from UV rays and environmental factors, visibility can decrease by up to 50%, making nighttime driving particularly hazardous.
We need to restore and clean oxidized headlights promptly to maintain peak safety.
We'll explore the essential steps for cleaning your headlights with WD-40, including proper preparation, application techniques, and what to avoid during the process.
Let's look at how this common household product can help restore clarity to foggy headlights, along with important safety precautions to keep in mind.
From initial cleaning to final protective coating, we'll cover everything you need to know about using WD-40 effectively on your vehicle's headlights.
Things to Do When Cleaning Headlights with WD40
Cleaning headlights with WD-40 is a popular and effective method to restore clarity to cloudy or oxidized headlight lenses. This simple yet powerful solution works by penetrating the surface layer of oxidation while temporarily rejuvenating the plastic, making it clearer and brighter.
The process requires careful attention to detail and specific steps to achieve the best possible results without damaging the headlight surface.
- Clean headlights thoroughly – Remove all dirt and debris using warm soapy water and a lint-free cloth.
- Prepare workspace – Cover surrounding areas with masking tape to protect car paint from WD-40.
- Apply WD-40 properly – Use a clean microfiber cloth dampened with WD-40 rather than direct spray.
- Circular motion technique – Work the product into the surface using gentle, consistent circular movements.
- Allow penetration – Let the WD-40 sit for 2-3 minutes to break down oxidation.
- Remove excess – Wipe away surplus WD-40 with a clean, dry microfiber cloth.
- Final cleaning – Wash the headlight with soapy water to remove any residual product.
- Protective coating – Apply car wax to create a barrier against future oxidation.
- Regular maintenance – Repeat process every few months to maintain clarity.
Things to Avoid When Cleaning Headlights with WD40
When cleaning headlights with WD-40, it's essential to understand the proper application techniques to avoid damaging your vehicle's lighting system.
Improper use of WD-40 can lead to reduced visibility, permanent damage to the headlight lens, and potentially unsafe driving conditions, making it vital to follow correct cleaning procedures.
- Direct application on dirty headlights: Creates a mixture of trapped dirt and lubricant that can make the cleaning process ineffective and potentially scratch the surface.
- Excessive product application: Results in a stubborn, greasy film that's difficult to remove and attracts more dirt.
- Using abrasive cleaning tools: Can create permanent scratches and damage the protective coating on headlight lenses.
- Cleaning in direct sunlight: Causes rapid drying and uneven application, potentially leading to streaking and poor results.
- Skipping the final wash: Leaving WD-40 residue on the headlights attracts dust and debris, causing faster deterioration of clarity.
