i have noticed that the inside of the housing for the headlights to my 01 mustang look to either have small cracks in them or they r just very dirty, is there a way to take the clear lense off from the housing to clean it? what do you clean it with and how is the best way to seal it all back up? thanx for all the help in advance

 

Buy new ones. They are glued together and you'll end up breaking them most likely trying to get them apart.

 

put them in a oven for about 5-10 mins and the glue will melt and then you can clean them
