What you will see

  • White or chalky spots on the glass after the panels dry.
  • Panels that look clean when wet but hazy when dry.
  • Output that does not fully recover after washing.

Why it happens

Tap water in parts of Lahore carries dissolved calcium and magnesium. When water dries on a hot panel, the minerals stay behind. Washing in the midday sun makes this worse because the water evaporates quickly.

What you can check yourself

  • Wash early in the morning or late in the evening when the glass is cool.
  • Use filtered or RO water for the final rinse if you have it.
  • Wipe or squeegee the glass dry after rinsing.

What not to do

  • Do not scrub stains with abrasive pads, powders or acids.
  • Do not use detergents or high-pressure jets.

When to call us

  • Stains will not come off with plain water and a soft cloth.
  • You would like a professional clean.

Panel washing in Lahore and Faisalabad

Tap water in much of Lahore and Punjab is hard. Rinse with filtered or RO water where you can, and ask us for a professional clean if stains will not shift.
