What is the shelf life of wiper blades?

[LolaRose]

The shelf life of wiper blades is not fixed, usually around one year. When the wipers show the following conditions, they should be replaced promptly. The specific situations are as follows: 1. Damage symptoms on the wiper blades: Visually check for cracks, rust, deformation, attachments, discoloration, etc. 2. Streaks on the windshield: During the use of wiper blades, if there are thin streaks left on the windshield, making it difficult to see outside, you can first clean the edge of the wiper. If the symptom persists, replacement is needed. 3. Wiper blades making harsh noises: If the wiper blades produce noise or jump and cannot rotate smoothly, it may be due to wax on the glass, wear of the rubber strip, damage to the arm and bracket, or aging and deformation of the rubber strip. First, clean the windshield. If the symptom persists, replacement is required. 4. Spotted water marks left after wiping: This is caused by rubber deformation or irregular wear, where the rubber fails to contact the glass surface, indicating that the wiper bracket is deformed and needs replacement.
