How do you remove window tint from your windows?

i bought a used car and it has window tint on the back. how can i get it off?|||done this a few times myself. Sharp razor blade. I find that if I wet the surface as i scrape it works well. The goo seems to come off easier that way. it is a bit of a work, but worth it. Footnote: if you have a rear defogger grid in the rear window, i wouldn't scrape it off. Just try to wet and wipe it off...|||peel it off, use a razor blade.|||Razor blade and possibly an adhesive remover like GOO-GONE|||use an adhesive remover but if u dont want to spend the money on the remover u could use a hair blow drier to loosen the adhesive then use a razor blade to peel it off it should come right up
