We were afraid of trying to remove the radiator, had no idea as to how. We ended up using a scraper securely taped to a pole to remove the wallpaper. After we cleaned up the wallpaper mess we used a paint sprayer to paint the raditor and the wall/baseboard behind it. Removal of the wallpaper took well over 1 hour, maybe even 2 hours. Painting the radiator with the sprayer took less than 2 minutes.
