How often should original wiper blades be replaced?

[DamianLynn]

Wiper blades are a type of wear-and-tear automotive product. It is generally recommended to replace them after one year of use or when any of the following three phenomena occur: 1. Thin water streaks: After the wiper blades sweep across, small water droplets remain on the windshield. This may be caused by issues with the wiper blade quality or oil film, etc. The residual water droplets on the windshield can easily cause blurred vision and affect driving safety. When this phenomenon occurs, the wiper blades should be replaced as soon as possible. 2. Scraping noise: Wiper blades are rubber products, and prolonged exposure to air can cause the rubber strips to age and the hardware to wear out. If the wiper blades produce a scraping noise against the glass when in use, they should be replaced promptly. 3. Banded marks: Wiper blades may leave streak-like marks on the windshield, affecting driving visibility and safety. This is often caused by incomplete adhesion between the wiper blades and the windshield or issues with the wiper arm hardware.
