How to remove vinyl adhesive?

[Jean-Claude]

The new work van I got had some vinyl letters on the glass. I scrapped the vinyl off but there was some adhesive still on the glass.



I have used scrubbed with a nap and used a bug sponge and they got most of it off. But there seems to be some amount still on. Almost how holograms look on paint....



Is there anything that is great for removing this stuff? Alky? Vinegar? Ideas?

razor blade and soap water works fine, i just tinted the windows on my daily driver and had to use that to get several adhesive stickers off

Remember to use a hair dryer, mineral spirits work great in addition to this.
