most of the time the headlight assemblys are replaced because of this at my work (toyota dealeraship ) but i would try to take apart the headlight assembly very carefully by prying up the tabs and glue that attach the front to the bach then clean out and reseal, or you could try to use a clothes hanger with a small amount of cloth or paper towel taped to the end and insert through the hole where the headlight bulb goes may take some time but could save you a considerable amount of money hope this helps
