ABSTRACT:
A scraper for refurbishing windscreen wiper blades has a frame with an outer periphery, at least one trimming groove defined in the outer periphery of the frame, and at least one scrubbing material respectively received inside the at least one trimming groove. The trimming groove receives a deteriorated rubber blade inside and slides to scrape surfaces of the rubber blade until the rubber blade becomes refurbished. Thereby, the rubber blade is trimmed conveniently and easily without excessive material loss.
