Best Headlight Cleaner

[MartinJ]

What is best product to clean dirty headlights?

Are they just dirty, or discoloured with age and UV affected - .ie. gone yellow ?

If just dirty try glass cleaner, elbow grease, then a bit of polish.

Its been known for people to try using toothpaste and plenty of elbow grease, if slightly foggy.
If UV damage, and yellowed, its a refurb thats needed. Either bravely by yourself or by someone used to doing it.
With this you really need to reapply UV lacquer afterwards
Plenty of tutorials about on the web

Thanks for that Toby. The headlights appear graiy-ish. I think they are just dirty.
