We've got about 210,000mi on the car at the moment, and the clear plastic lenses for the headlights are getting decidedly yellowed/murky after so long - they're getting to the point where taping candles to the front of the vehicle might be more effective ;)
I keep seeing ads for some sort of restorative polish stuff (which may well be snake oil) - but it got me wondering if a DIY concoction might be worth a try - e.g. I've found in the past that combinations of toothpaste and baking powder work very well for removing scratches from CDs, for instance, but I wondered if anyone can recommend any other home remedies? :-)
cheers
Jules
