A while ago I ran across a Nissan Service Bulletin that cautioned against using alcohol on light lenses. I thought it was interesting that they'd bother to issue a TSB on such a subject.
Well, last weekend I had to replace a cracked lens on my Nissan. So, I decided to experiment on the old one. I wiped it with alcohol on a rag and it looked fine. Then I noiticed that the crack that was in it was getting longer as I watched. Hard to believe, but the crack continued to get longer (1 inch) until I washed it with water. Then it stopped. I tried again later with wood alcohol, same results. I didn't try using a water alcohol mix, but I might test that soon.
Not sure if it's a specific Nissan type plastic, but I suspect not. So, keep the alcohol away from the plastic !
FYI,
Bob
