STEP THREE: ADHESIVE REMOVAL
This step is extremely important, and will determine the quality of your job from the outset. Spray the window with a degreaser or soapy water, something strong enough to remove glues and adhesives. After letting it soak in for a couple of minutes, grab your scraper blade and start scraping the glue residue off. Wipe any excess adhesive build-up from your scraper onto a rag. You will want to change blades between windows to keep things clean and tidy. Obviously on your rear window you can’t go using a scraper blade, because you will damage your demister element. Once the tint has been removed on the rear window, spray it with a copious amount of heavy-duty degreaser. After letting the degreaser work its magic, start wiping off with paper towels, and then rags to get the last of it off. Work your way around the car, removing every last bit of adhesive — the prep is worth the end result.
