Step-4: Move to Rubbing Alcohol

Once you’re done with cleaning the dirt, you are to work on the hazing. For that, you need to clean the cleaning tool at first and then dip that into rubbing alcohol.

Now get that cleaning tool to the inner side of the lens and carefully wipe off all the dirt, dust, and stain. It will be quite difficult and will take quite some time. Be patient and careful enough for the best results.

Step-5: Cleaner Headlamp Ever

Continue wiping and rinsing until you get back your spotless, shiny headlamps. Now read the owner’s manual once again to put the headlamp back into its place.
