Now that winter's here, I'm finding I have a huge problem with white crud building up on my headlights. When the pavement's wet, the light output will drop to unusable levels within a single trip. Does anyone know whether there are factory or aftermarket headlight washers that would work on a G?

 

I believe Plasticx by Meguiars works well to remove what you are speaking of

 

I don't believe there are any headlight washers available.
