How to Clean Headlights with Brake Fluid?

Headlights become yellowish over time. And most drivers, including you, might find it troublesome in the middle of the night.

There are multiple reasons that your headlights are turning foggy. One of the most common one is UV exposure.

The protected plastic layer that headlights have on their surface wears away due to the UV rays. Thus, the yellowish hue pops up on the headlights.

So in this case, the quickest remedy is to clean the headlights with brake-fluid, the most effective and easiest hack. Here’s everything you need to know about cleaning headlights with brake-fluid.

Why do Your Headlights Get Foggy?


UV rays from the sun oxidize the headlights which peel off the protected coating from its surface. So, the headlights look foggy and yellowish.

Water Vapor

When it’s raining, sometimes the raindrops accidentally enter the compartment of the headlights. Or sometimes, while washing the car, water may enter too. The remaining water inside vaporizes due to heat. And it forms the cloudy tint inside the lens.


While driving the car, many dirt particles come across the headlights, which somehow enter the compact headlights. And they form dust circles inside the glass. Moreover, when the white sand sticks with the headlights it scratches the surface which causes the lights to go in separate ways rather than in a focused point.

Use of Unnecessary Products

Lots of extra acidic liquids are available in the department store which may cause harm to the headlights. Also, it gets foggy while wiping headlights if enough amount of pressure is given.

Things that You Need to Clean the Headlights


Grab a small container of brake-fluid from your near departmental store or you can get it from your local garage too.

Towel or Sponge
