How to remove CDF adhesive film from a window
Method 1: Cut 4-inch strips and peel off what you can. Make sure the glass is wet with soapy water, and then use a single-edged wall scraper with stainless steel blades to scrape away the residual pieces. Afterward, do a last wipe-down with acetone. If you plan on putting HPR or PS adhesive on next, you must make sure to get all the CDF off.
