Don't use alcohol to remove water from inside the taillights. Saw some water in the tail lights, thought it would be easy to use some alcohol to dry out the water then allow the alcohol to weather off, to speed it up I used a hair dryer. Big, Big, Big mistake! The alcohol etched/stained the lens from the inside. Looks really bad, didn't want to go though the trouble of cutting the lens off to try to buff the stain off. I'm going to need to get some new tail lights. Until then I tinted the lens from the outside, can still see the stain when the brake lights illuminate. Yeech! Oh well lesson learned.
