Why does my Hyundai Oshan X7’s windshield show streaks after using the washer spray?
Whenever I use the washer spray on my Oshan X7, the windshield doesn’t clean properly and leaves visible streaks. Is it because of the water quality o r the washer fluid? What kind of washer solution is best for Pakistan’s dusty conditions?

You’re using tap water o r low-quality washer fluid, which leaves minerals and residue on the glass.
The washer nozzles o r hoses are clogged with dust o r scale, causing uneven spray.
Old washer fluid o r improper mixing leaves streaks instead of cleaning.
Solution:
Use a dedicated windshield washer fluid, not plain water. Brands like STP, Sonax, o r Meguiar’s are available in Pakistan.
Clean o r unclog washer nozzles using a fine pin o r compressed air.
Avoid filling the reservoir with hard tap water, especially in cities like Lahore o r Islamabad where mineral content is high.
