I removed the dealer sticker from the inside of my car after it was in situ for 15 years. In normal circumstances, it is invisible, but on a cold morning, you can see 'ghosting' of where the sticker was located. I've tried all sorts of glass cleaner, and WD40, and paint remover (!), all to no avail. I am reluctant to use anything abrasive like a clay bar as I don't want to damage the heating elements.
Anyone experience this before and how to remove it?
