This is the patented wiper blade that scrubs through windshield debris, leaving a clear, streak-free view of the road. Unlike common windshield wipers that can smear and obstruct your field of vision, this patented wiper employs dual blades-the outer edges of which have hundreds of tiny triangular scrubbers-that completely remove bugs, bird droppings, frost, and dirt in just a couple of passes. The inner edges of the blades channel water and debris off the windshield, resulting in a clean, unhindered view. Unlike lesser blades that crack or tear, in independent laboratory tests the durable composite rubber blade maintained its remarkable cleaning ability even after 500,000 cycles. Installs easily on most types of wiper arms without tools. Wiper blades must be ordered individually as driver and passenger side lengths may differ.
