FLAT WIPER BLADE / PREMIUM

■   The flat wiper blade is a one-piece, flexible wiper blade that differs from traditional multi-frame wipers. It eliminates the complex metal frame, with its core consisting of a single piece of high-elasticity memory steel sheet and a premium-grade rubber wiping element.
■   Relying on the uniform spring force of the internal steel strip, the blade automatically conforms to the windshield's curvature, ensuring full and even contact across the entire surface. This prevents issues such as partial lift-off, streaking, unwiped areas, and chattering.
■   Compared with conventional wiper blades, this design offers a simpler structure, quiet and streak-free wiping, excellent UV and aging resistance, reduced deformation, and no damage to the windshield. Suitable for year-round use, easy to install, and widely adopted as a mainstream upgrade replacement for original wiper blades.

■   Premium Core Material: Bekaert Steel from Belgium. High elasticity, precise conformability, rust resistance, and long-lasting durability.
■   The core steel strip used in MASUMA flat wiper blades is sourced from Bekaert, the globally renowned steel supplier from Belgium. As an industry-leading manufacturer of steel wire products, Bekaert is recognized for its high-purity steels, excellent elasticity, and exceptional toughness, and its products are widely used in premium industrial applications and OEM automotive systems.
■   MASUMA selects 60C high-carbon spring steel, sourced from globally renowned Belgian supplier Bekaert, to produce the wiper's core spring sheet.”This material provides outstanding elastic recovery, ensuring constant and close contact with the windshield throughout operation. Regardless of the windshield’s curvature, it delivers full-surface wiping coverage, effectively removing rain, dust, dirt, and other contaminants to restore clear driving vision. In addition, the 60C steel undergoes a specialized anti-corrosion treatment that forms a dense protective layer. This helps resist rust and degradation caused by rain, humidity, salt spray, and other corrosive conditions. Even in coastal regions or during prolonged rainy seasons, this effectively prevents rust, corrosion, and breakage, significantly extending service life while reducing the frequency and cost of replacement. Its quality is engineered to meet stringent OEM standards.

■   MASUMA flat wiper blades use chloroprene rubber (CR), a mainstream material widely adopted in OEM wiper systems. CR offers excellent weather resistance, abrasion resistance, and elasticity, allowing it to perform reliably under a wide range of climate conditions while resisting UV exposure, extreme heat, and freezing temperatures to prevent aging, hardening and cracking over time.
■   To further improve the user experience, MASUMA specially adds a graphite coating treatment to the surface of the chloroprene rubber strip. The graphite coating enhances the lubricity of the rubber strip and reduces the frictional resistance between the rubber strip and the windshield, achieving quiet wiping and eliminating the sharp “squeaking” noise in rainy weather. It also forms a protective barrier that slows the aging of the rubber strip caused by prolonged sun exposure and dry wiping, extending its effective service life. Each wipe remains smooth, quiet, and clean, comparable to the experience of OEM wiper blades.
■   Wide-Temperature Performance: Reliable Wiping in All Conditions
Automotive travel conditions are complex and changeable, and wiper blades must face extreme climate tests such as high-temperature sun exposure and low-temperature freezing. MASUMA flat wiper blades follow OEM-level performance standards. Through scientific material selection and structural design, they achieve excellent wide-temperature resistance and can maintain stable wiping performance in different temperature environments, safeguarding car owners’ travel in all scenarios.

■   To maintain optimal wiping performance and extend service life, please follow these guidelines:
1. If coated wiper blades were used previously, before replacing with this product, the windshield must be thoroughly cleaned. Use a professional oil-film remover to remove any residual coating or oil film, ensuring proper blade-to-glass contact.
2. During daily use, ensure proper wiper arm tension. If wiping leaves water marks (insufficient pressure) or the rubber strip shows excessive wear (excessive pressure), contact a professional for adjustment.
3. Regularly clean the windshield and remove debris such as sand, leaves, and bird droppings. Avoid dry wiping or friction from debris that can damage both the rubber strip and the glass.

■   Rubber strip cleaning: Rinse the rubber strip with clean water weekly. For oil or grease buildup, gently wipe with a mild detergent, then dry before use.
■   Avoid extreme use: Do not dry-wipe the glass. For extended parking in direct sunlight, lift the wiper arms away from the windshield to reduce heat aging of the rubber.
■   Regular inspection: Inspect the rubber strip for cracks or hardening, and check that the steel strip and connector are secure. Address any issues promptly.
FAQ
Q: What should I do if the wiper makes noise?
A: First, clean any oil film or debris from the windshield. If noise persists, check and adjust the wiper arm tension. Replace the wiper blade if the rubber is worn or aged.
Q: Why does the rubber strip age quickly?
A: Frequent dry wiping, debris on the windshield, prolonged sun exposure, and failure to promptly remove corrosive substances such as bird droppings and tree sap.
Q: How do I fix water marks left after wiping?
A: Clean any oily film from the windshield, check the rubber strip for damage and ensure proper wiper arm tension, and confirm the wiper size is compatible with your vehicle model.
Q:  Why does the wiper not work in low temperatures?
A:  First remove frost from the glass, then melt it with warm water before use. Do not force the wiper to start.
