Why Do My Exterior Windows Get Dirty So Fast After Cleaning?

The Quick Answer:
Exterior windows usually get dirty quickly due to three main factors: hard water residue from garden hoses, static electricity attracting dust, and airborne pollutants like construction dust or tree pollen. Using professional-grade, purified water and specialized squeegee techniques prevents the static and residue that attract dirt, keeping windows cleaner for longer.

The Culprits Behind Rapid Window Grime

Many homeowners in urban environments like Toronto or Markham notice their windows look dirty just weeks after a DIY wash. Here is why:

• Hard Water Spots:
  Tap water and garden hoses contain minerals like calcium and magnesium. When the water evaporates, it leaves behind a chalky, white film.
• Residue from Improper Soaps:
  Dish soaps leave a sticky, invisible film on the glass. When the wind blows, dust and pollen stick directly to this film.
• Environmental Factors:
  The GTA has high levels of construction dust, vehicle exhaust, and seasonal pollen (especially in heavily treed areas like Aurora or Newmarket).
