Are local car wash centers using oily cloths o r detergent-rich water that leave a layer behind, worsening visibility?

Yes. Many local car wash stations in Pakistan use:

Unfiltered tap water

Old o r oily rags

Detergents with high residue
This leaves behind a film that worsens during wiping. Such residues also interfere with the effectiveness of rain repellents and washer fluid. Alsvin owners should opt for clean microfiber drying cloths and avoid waxy detergents on the glass.
