The replacement cycle of car windshield wipers is usually recommended to be 6 to 12 months, but the actual replacement time needs to be comprehensively determined based on the material, frequency of use, and environmental conditions. Rubber wipers age faster in high-temperature, rainy, or dusty environments, so the replacement interval may need to be shortened to 4 to 6 months. In contrast, silicone or polyurethane wipers, due to their strong weather resistance, can have a service life extended to 2 to 3 years. In daily use, if there are residual water marks after wiping, cracked rubber strips, abnormal noises, or skipping during operation, the wipers should be replaced immediately to ensure driving safety in rainy weather. When purchasing, attention should be paid to matching the vehicle model specifications, and priority should be given to high-quality products with anti-aging treatment. It is recommended that car owners check their working condition every six months and replace ineffective products promptly.
