A wiper protector fits over a rear window wiper to prevent damage to the wiper from a mechanized or automated car wash. The wiper protector is open on one end for slipping over the wiper blade, arm and wiper motor components if exposed. The sleeve includes a cutout at the open end to fit over the wiper motor components. A drawstring near the open end passes through the sleeve guided by non-marring grommets near the sleeve open end. A drawstring lock maintains tension on the drawstring during use.
