## Description

Bosch Clear Advantage Wiper Blades feature a patented beam design that reduces exposed metal for greater resistance to ice and snow build-up for improved all-weather performance. The blended natural rubber blade, with graphite treated wiping edge, reduces friction for a quiet and smooth wipe in all seasons. Clear Advantage wiper blades include an aerodynamic wind spoiler that creates downward force which ensures superior windshield contact for consistent wiping at higher speeds. The versatile Click-On adapter system - compatible with most vehicles - ensures quick and easy installation. Included adapters fit: 9x3mm Hook, 9x4mm Hook, 4.8mm (3/16 inch) Small Pin, 6.35mm (1/4 inch) Large Pin, Side Lock, 16mm Narrow Top Lock (select lengths only), 19mm Large Top Lock, BMW Top Lock, Pinch Tab.

Review: Best wipers ever! - I originally paid over $40. at an auto store and I must say it was like throwing my money away. Worst wipers ever very noisy and left streaks. I then went to desertcart and ordered the Bosch wipers. They’re wonderful, quite no streaking. Will definitely be ordering these again. I highly recommend. Excellent quality.
Review: Works Great, Easy Install, and a Solid Value - I picked up this Bosch 22CA wiper blade for my Ford Explorer. The price was excellent, and it worked flawlessly right out of the package. Installation was quick and easy, no tools required, and it snapped right into place. The blade gives a clean, streak-free wipe even during heavy rain, and it's noticeably quieter than some of the cheaper blades I’ve used in the past. Like any wiper blade, I know the Southern heat will eventually wear it down over time, and streaking can start even with minimal use. I've heard people recommend lifting the wipers off the windshield when parked, but honestly, I probably won't bother. At this price point, it's an easy and affordable swap when the time comes. If you’re looking for a reliable replacement that performs well and doesn’t break the bank, I definitely recommend this one.

### ⭐⭐⭐⭐⭐ Excellent beam type wipers
*by R***M on December 30, 2025*

As good as any premium priced wiper, at a mid-line price. They last well too, I've gotten about a year of acceptable use out of several different fitments of this type Bosch wiper, most other non-silicone brands are ready for replacement in 6 months.
