I not a vaper so take this with a grain of salt. Water and white distilled vinegar is some of the best window cleaner you could ever make yourself.. I mix it like 4 parts water 1 part vinegar... Works to clean the rest of the plastics and dash on truck as well.
Dawn. Used to wash windows and tried every cleaning product known to man and nothing ever worked as well as just using dawn. Just mix a tiny bit of dawn with water and dampen a rag and then wipe dry. Also keeping a bottle helps if you put it on the squeegee when you wash your windows. Gets rid of bugs amazingly.
