I won't use Windex With Ammonia on anything expecially on the back of a translite which can be costly. I believe ammonia can harm after market window tints too. I've been using 3 parts distilled water, 1 part 91% isopropyl alcohol, and 8 or 10 drops of Dawn dish liquid for each quart. Works great, is cheap as heck, and doesn’t contain ammonia. I use this to clean all the glass surfaces too.
