Why window cleaning matters for your home or business

Regular, professional window cleaning enhances not only your property’s appearance but also its performance and longevity. From amplifying natural light and improving outdoor views to maintaining property value and preserving structural integrity, the advantages are clear.

In residential settings, well‑maintained windows invite light, space, and warmth into every room, instantly refreshing your home’s atmosphere and curb appeal. For businesses, sparkling glass is part of their brand presentation; it signals professionalism, pride, and attention to detail.

Learning how to approach cleaning glass windows like a professional goes beyond simple wiping. It’s about protecting your investment by preventing long‑term issues such as mineral build‑up, corrosion on frames and compromised seals. Clean windows don’t just look better - they function better, extend your building’s lifespan and reflect the care you take in every detail.

What's the best way to clean windows without streaks?

Nobody wants cleaned windows only to find streaks, smudges or hazy films. Achieving streak‑free window cleaning is all about knowing the right steps and avoiding common mistakes.

Here’s how to approach it:

  1. Use a specialist window‑cleaning solution or a mild detergent mixed with purified water rather than just a multipurpose cleaner.
  2. Start at the top of the glass pane and move downwards. This prevents dirty water from flowing over cleaned areas.
  3. Clean squeegee blade between strokes to remove residue.
  4. Follow with a microfiber cloth or lint‑free towel to buff corners and edges where squeegees can’t reach.
  5. Avoid cleaning in direct strong sunlight or very windy conditions (rapid drying often causes stains or streak lines).
  6. Use filtered or de‑ionised water to reduce mineral spots on glass whenever possible.
  7. Ensure you clean both inside and outside surfaces - neglecting one side often compromises the other.

These steps form the foundation of the best way to clean windows without leaving trace marks. When you apply them consistently, your windows look professionally finished rather than just superficially clean.

What do the pros use? The best solutions and tools for window cleaning

Once you’re comfortable with the technique, it helps to know what professionals bring to the job. The right equipment and solutions make a real difference in finish, efficiency and safety, particularly when doing large‑scale or challenging glazing.

[section_inner_1 id="high-quality-squeegee" format="overview"]

High‑quality squeegee

The squeegee is the cornerstone of professional window cleaning. A well‑made squeegee with a sharp, flexible rubber blade ensures even pressure across the glass, leaving a clean, streak‑free finish. Professionals use different sizes to match window dimensions, providing precise results every time.

[/section_inner_1]

[section_inner_1 id="microfiber-cloths" format="overview"]

Microfiber cloths

Microfiber cloths are essential for detailing and polishing. They effectively capture dust, dirt, and moisture without scratching the surface or leaving lint behind. These cloths are perfect for touching up corners, edges, and window frames after the main cleaning for a flawless finish.

[/section_inner_1]

[section_inner_1 id="extension-and-water-fed-poles" format="overview"]

Extension and water‑fed poles

For high or hard‑to‑reach windows, extension poles and water‑fed systems are indispensable. They allow professionals to clean safely from the ground while maintaining control and efficiency. These tools are especially useful for large commercial properties or multi‑storey homes where safety and consistency are paramount.

[/section_inner_1]

Using these tools elevates a job from DIY to a professional‑level finish. At Bax Clean, we come equipped with specialised gear and expertise, guaranteeing clean windows as well as lasting clarity and value.

How to tackle tricky windows: high, double pane and floor-to-ceiling

Some windows present a greater challenge, such as high-level façades, insulated double-pane units, or expansive floor-to-ceiling glazing. For those, a structured, step‑by‑step approach using professional window cleaning techniques is essential.

  1. Assess the window type: Identify whether it’s a standard single‑pane, a double-pane window unit (insulated glazing) or floor‑to‑ceiling glass.
  2. Select the correct access method: For high windows, consider extension poles or water‑fed poles, or harness/rope access if needed. WorkSafe Victoria provides clear guidelines on high-access window cleaning.
  3. Prepare your cleaning solution and tools: For double-pane glazing, avoid excessive water pressure or harsh chemicals that may damage the seal. For large panes use longer-reach squeegees and cloths.
  4. External surface first: Remove built‑up grime such as bird droppings, tree sap, and pollution residue. Then apply the solution and squeegee from top to bottom.
  5. Internal surface next: Use an appropriate ladder or scaffold. Work systematically, clean the frame and sill after the glass so re‑settling dirt is minimised.
  6. Inspect the unit: For double-pane windows, check seal edges for moisture ingress or edge staining. If compromised, cleaning alone may not be enough, and you should recommend specialist replacement or repair.
  7. Final detailing: Use microfiber cloths to polish glass and frames, inspect for streaks or missed spots, and touch up as needed.
  8. Safety wrap‑up: Clear equipment, secure ladders/poles, ensure no water is pooling, and ensure access points are safe. A professional job includes post‑job clean‑up and site restoration.

At Bax Clean, our experts handle even the most challenging glazing with precision and care, delivering a spotless, high‑quality finish every time. Reach out today to see how we can make a difference.

What’s the best window cleaning method for your home?

No two homes are the same. A single‑storey suburban home with standard windows is very different to a townhouse with restricted access, or a property with expansive floor‑to‑ceiling glass walls. The correct technique should balance effectiveness, safety and cost, so you’re not overpaying for something simple, nor underpreparing for a complex job.

  • For standard accessible windows on a single‑storey home, a classic squeegee and microfiber cloth combo is efficient and cost‑effective.
  • For townhouse or apartment living where external access is limited, a water‑fed pole system or hiring a specialist with harness‑access may be the safer and smarter route.
  • For homes with floor‑to‑ceiling glazing, engage a professional service that brings long‑reach tools and knows large‑format glazing cleaning.
  • For properties with insulated or double pane window cleaning units, choose a professional who understands seal issues and won’t risk compromising the glazing unit.
  • For mixed or complex properties (double storey, skylights, large glazing, restricted access), a comprehensive professional service provides the consistency, safety, and technique you need.
