I just bought a 98 Contour LX with the 2.5 liter Duratech and my only complaint so far is that at the top of the headlight lenses, there is a foggy look to them.. but it feels like there's some kind of residue on the outside of the lense rather than it all being on the inside. Does anyone know if there is a product available to clean this or the inside? Just looking for some options other than shelling out 300 bucks for new lenses. Thanks.
