Clean windows make an enormous difference to how a home or office looks and feels. Yet window cleaning is one of those tasks that, done incorrectly, leaves things looking worse than before.
Why DIY window cleaning often fails Household glass cleaners and paper towels are notorious for leaving streaks. The culprit is usually the cleaning solution itself — many retail products contain wax or silicone that builds up over time.
The professional approach:
- Pre-rinse to remove loose dirt and debris.
- Apply a professional-grade solution — typically a small amount of dish soap in warm water.
- Use a squeegee with a clean rubber blade, working from top to bottom in overlapping strokes.
- Dry edges immediately with a lint-free cloth to prevent drips.
- Buff the glass with a dry microfibre cloth for a streak-free finish.
When to call a professional: For anything above ground level, for large commercial glazing, or for removing hard mineral deposits (hard water stains), professional equipment and training are required. High-reach water-fed pole systems deliver a pure-water rinse that leaves glass spotless without any chemicals.
Regularly cleaned windows also last longer — mineral deposits and oxidisation can permanently etch glass if left untreated.
