I recently noticed headlamp haze on my 00 Tundra and tried to clean it off. I used a product called Bartender's Friend and used to a sponge to clean the headlamp. i washed it off and the lens looked crystal clear, like new. I let it dry and when I came back 20 minutes later it was back to hazy. Should I be using a better solvent to clean this off? Attacking it with a rougher pad? I know these are all temp. fixes but I heard people getting them clean for at least 6 months.. Thanks!
