Why does my Mercedes-Benz S-Class windshield develop streaks after using the wipers?

Many Mercedes-Benz S-Class owners in Pakistan notice streaks forming on the windshield when using the wipers, especially during o r after rain. What are the common causes of these streaks in the local climate and road conditions? How can poor windshield cleaning products o r wiper blade quality contribute to this issue?

Streaks on the windshield often occur due to worn-out o r dirty wiper blades that fail to clear water evenly. In Pakistan, dust, pollution, and residue from oily road grime can accumulate on the windshield, making it harder for the wipers to work effectively. Using low-quality windshield washer fluid o r skipping regular cleaning can worsen the streaks. Additionally, heat and sun exposure can cause rubber wiper blades to dry out and crack, reducing their efficiency. Regular cleaning of the windshield and timely replacement of wiper blades help prevent streaking.
