These window scraper blades serve as compatible spare parts for handheld glass cleaning scrapers. Manufactured with precision grinding technology, the blades maintain uniform sharp edges to strip tape residue, paint splatters, cement stains and limescale from glass, mirrors and tiles efficiently. Carefully controlled thickness delivers balanced cutting performance; the smooth edge avoids scratching smooth hard surfaces with proper operation. Standard size design ensures seamless installation into matched scraper handles without trimming. Packed neatly for convenient storage and batch usage for cleaning teams, construction crews and commercial maintenance work. Custom blade dimensions, thickness and surface treatments are available for overseas bulk buyers.
