Bosch MicroEdge 20" Conventional Wiper Blade — 20in Quiet, Corrosion-Resistant Steel Frame

Engineered to deliver consistent visibility in wet conditions, the Bosch MicroEdge combines a precision-cut natural rubber wiping element with an aerodynamic steel frame. Its enclosed tension spring and QuietGlide micro-finish help reduce chatter and noise while an exclusive zinc dichromate primer and powder coats protect the frame from corrosion. The pre-mounted QuickClip adapter speeds installation on a wide range of common wiper arms.

How does this wiper blade keep windshield streak-free?

The MicroEdge uses a specially blended natural rubber that is precision cut to a micro-finish edge, reducing friction and wiping streaks. The enclosed, tensioned metal spring keeps even contact across the blade length for consistent wiping performance.

• Precision-cut natural rubber wiping element for clear visibility
• QuietGlide micro-finish reduces friction and chatter
• Enclosed metal tension spring maintains uniform pressure

What makes the frame durable against rust and wear?

Bosch protects the all-steel frame with a multi-layer corrosion system including a zinc dichromate primer and two layers of powder coating. Clipped joints reduce exposed hardware and help minimize noise while preserving the frame structure over time.

• Zinc dichromate primer plus dual powder coats for triple corrosion protection
• All-steel aerodynamic frame for strength and reduced wind lift
• Clipped joints designed to decrease noise and maintain alignment

Is the MicroEdge easy to install on most cars?

The blade ships with Bosch’s pre-mounted QuickClip adapter for faster, tool-free installation on many popular wiper arm types. Compatibility depends on arm design, so use your vehicle fit checker to confirm the correct blade for your car.

• Pre-mounted QuickClip adapter fits multiple arm styles (hook, pin, bayonet, side saddle, etc.)
• Designed for quick, secure snap-on installation
• Check vehicle Year, Make, Model to ensure exact fit

How does this blade perform in everyday driving conditions?

The combination of a robust steel frame and a finely finished rubber edge provides reliable wiping across rain, mist, and light debris. Its aerodynamic design helps resist lift at highway speeds while the QuietGlide finish minimizes operational noise.

• Aerodynamic frame reduces wind lift at higher speeds
• Quiet operation through reduced edge friction
• Consistent contact across variable temperatures and conditions
