Exactally what I do...Peel off the tint, soak the glue with glass cleaner, let sit for 5 mins, spray again and scrape away. We've got a steamer at the shop but i only use that on old purple shit and back windows.
brake cleaner will eat shit up in a hurry, dont get that on anything. i ahve seen a can of berrymans turn a section of asphalt into tar.pretty sure they use steam to heat the glue, then scrape/peel //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif
I used brake cleaner and a razor once //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif
x2 easiest way to do it //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.giftake a black plastic bag, tape it to the inside of the window, have it in the sun, let it bake, it will peel off clean.
