How to Clean Headlights From the Inside

As we use our cars regularly, the headlights can easily get dirty both from the outside and inside. While cleaning the outside of headlights is a common practice, many people tend to neglect the inside of their headlights. However, it is essential to clean both sides of your headlights for better visibility while driving at night or in harsh weather conditions.

How to Clean Headlights From the Inside

In this guide, we will discuss how to clean headlights from the inside and why it is necessary.

Why Clean Headlights From the Inside?

The outside of the headlights can get dirty with dust, dirt, bug splatters, and other debris. However, the inside can also accumulate dirt, moisture, and condensation over time.

This build-up can create a foggy or hazy appearance on your headlights, affecting the brightness and range of your lights. It can also lead to discoloration or yellowing of the plastic lens, which not only looks unappealing but also reduces the effectiveness of your headlights.

Moreover, dirt and moisture inside the headlights can cause electrical issues, potentially leading to expensive repairs. Therefore, cleaning the inside of your headlights is crucial for maintaining their functionality, appearance, and safety.

Necessary Items

Before we dive into the cleaning process, let’s gather all the necessary items. Here’s what you will need:

  • Microfiber cloth
  • Cleaning solution (water and soap or specialized headlight cleaner)
  • Small brush (toothbrush or soft-bristled brush)
  • Plastic cleaner/polish (optional)

8 Things to Know Before You Start

1) Check Your Car’s Manual

Before beginning the cleaning process, it is vital to check your car’s manual. Different car models may have different methods of accessing and removing the headlights. Therefore, it is essential to follow the specific instructions for your vehicle.

2) Park in a Well-Lit Area

It is recommended to park your car in a well-lit area before starting the cleaning process. This will help you see the inside of your headlights more clearly and ensure that you clean all areas properly.

3) Safety First

Make sure to wear gloves and eye protection during the cleaning process to avoid any potential hazards. If using a specialized headlight cleaner, be sure to follow the safety instructions on the product label.

4) Use a Microfiber Cloth

When cleaning the inside of your headlights, it is crucial to use a soft and lint-free cloth. Microfiber cloths are ideal for this purpose as they won’t scratch or damage the plastic lens while effectively removing dirt and moisture.

Avoid using harsh chemicals such as ammonia-based cleaners or household cleaners on your headlights. These chemicals can damage the plastic lens and affect the effectiveness of your headlights.

7) Be Thorough

When cleaning the inside of your headlights, make sure to cover all areas, including the corners and crevices. This will ensure that you remove all dirt and moisture build-up for maximum effectiveness. And remember, patience is key!

8) Consider Using a Plastic Cleaner/Polish

If your headlights are severely discolored or yellowed, you may want to consider using a plastic cleaner or polish after cleaning. These products can help restore the clarity and shine of your headlights and protect them from future damage.

Consider Using a Plastic Cleaner

Cleaning the inside of your headlights is a simple task that can have significant benefits in terms of safety and appearance.
