Pip 12 Posted August 20, 2018 Hi there. Just taken a px in with plastic headlights that are misty. Someone said try wd40 on them to which I laughed. So yesterday I thought why not and gave it a try. No hard rubbing and they have come up like new. Crystal clear. Has anyone else heard this or tried it before? Just looked 5 minutes ago and they look as new.
