Start with a clean glass microfibre cloth for everyday fingerprints and smudges on windows you can reach safely, provided the glass maker allows it. Newspaper can wipe a pane but may leave ink behind. Keep the standard pressure-washer nozzle off the window. A dedicated glass kit needs its own checks, especially if you’re unsure what’s on the glass or how the window is sealed.

Which window-cleaning method should you use?
Choose the tool after you’ve checked the pane. A suitable cloth usually handles fingerprints on a small pane. For larger panes, a squeegee can speed up the finish if the glass maker allows it. Grit, coatings and awkward access can all change the choice.

Check the pane, the dirt and your access
- Pane. Applied film and exposed low-E heat-control coatings can need different care from plain glass. Ask the installer if you’re unsure.
- Dirt. Lift loose grit before wiping. Stubborn spots may need assessment.
- Access. Clean only what you can reach from stable footing without leaning out.
Can you clean windows with a pressure washer?
Keep a standard pressure-washer nozzle away from windows. A direct jet can dislodge seals or damage frame components. Hand-cleaning is the better choice for routine dirt on reachable panes. A dedicated glass attachment is a separate setup with its own equipment and surface requirements.
Why a standard pressure-washer nozzle is a poor choice?
The edges of a pane are where the glass, seals and frame meet. Keep pressure spray away from those joints. If the glass is cracked, the frame is loose or water is coming indoors, stop and have the window assessed.
Can you use a Kärcher pressure washer to clean windows?
Yes, if your exact washer is compatible with Kärcher’s dedicated façade and glass cleaning kit and your window manufacturer allows that method for the pane and frame. Kärcher Australia lists the kit for windows. If the window guidance is unclear, use a compatible hand method.
- Match your exact washer model to the kit’s compatibility list.
- Read the instructions for the glass attachment.
- Check the window maker’s care instructions for the glass, seals and frame.
A Kärcher Window Vac picks up wash liquid by suction after you’ve washed the pane.
Can you clean windows with newspaper?
Newspaper can wipe liquid and light dirt off glass, but the finish varies with the paper and the ink. A clean glass cloth is a better everyday choice. Check the care instructions before trying a different wiping material, especially if the pane has an applied film or coating.
Why newspaper can work and why results vary?
Newsprint caught on as a disposable wipe. A cleaner interviewed by ABC News noted that ink can transfer from paper to glass. Viridian advises against substituting newspaper for a cloth.
What to reach for instead?
Use a soft, clean glass cloth for a small reachable pane. A squeegee can clear wash liquid faster on larger panes where permitted.
Can you clean windows with a microfibre cloth?
Yes. A clean, soft microfibre cloth works well for fingerprints and light smudges on compatible glass. Keep a second cloth dry so you can take up the moisture left by the first pass. On a filmed or coated pane, check what the manufacturer allows.
Choose a clean glass cloth and keep one dry
Swap the finishing cloth when it starts leaving trails of water. Set aside any cloth that picks up grit. Use separate cloths for frames and tracks, where grit can collect.
Can you use a KoalaCloth to clean windows?
KoalaCloth works for light dirt on glass where the care instructions allow it. The brand recommends using one cloth for the damp pass and keeping the other dry. Two suitable glass microfibre cloths can do the same jobs.
- Lift light dirt with the slightly damp Mini or LITE.
- Take up the remaining moisture with the dry XXL.
How to clean reachable windows without streaks?
Set out clean cloths so you can finish before the wash dries.
Clear the grit, wash the pane and dry the edges
- Check the surface and your footing. Confirm which tools and liquids the glass or film maker allows. Leave any part you can’t reach safely.
- Wait for shade. Work on cool glass so the wash liquid stays wet long enough to remove it.
- Lift loose grit. Clear it from reachable sills and frames first. Lift grit from the pane with a compatible damp method and avoid dry scrubbing.
- Wash the pane. Apply a permitted cleaning liquid with a clean cloth or another approved tool.
- Remove the wash liquid. Use a dry glass cloth or a permitted squeegee. Dry the edges where water collects.
Tell a wipe mark from a problem that needs assessment
See whether the mark moves after one compatible pass. Leave cracked or loose glass alone. Haze inside a sealed double-glazed unit warrants assessment.
| What you see? | What to do next? |
|---|---|
| A smear shifts with a fresh cloth | Likely surface residue. Try one more compatible wash. |
| Chalky spots stay after washing | They may be deposits. Check the approved treatment or ask a cleaner to assess them. |
| Haze between panes, cracked glass or indoor leaks | Contact the installer, a glazier or your property manager for assessment. |
When to book professional window cleaning in Sydney?
Choose who to call based on the window’s condition and access.
Decide who should handle the window
- DIY. Clean ordinary dirt from a reachable pane if you know how to care for the surface.
- Window cleaner. Ask how the cleaner will manage elevated exterior access. For a busy shopfront, agree on timing around foot traffic.
- Strata or property manager. For an inaccessible apartment exterior, confirm who arranges cleaning and what access is approved.
- Glazier or installer. Arrange an assessment for damaged glass or a suspected fault with the window.
What to include in a Westlink quote request?
Share your suburb, property type, approximate pane count and number of storeys. Say whether you need the inside, outside or both cleaned. Describe the dirt and any access constraints, and include photos if you can take them from stable footing. For a commercial site, add access hours and a site contact.
Pane size, condition and access can affect the quote. Ask for any screens, tracks, frames or sills you want cleaned to be listed separately.
FAQs
Can I clean window film straight after it’s installed?
Wait until the film maker or installer says the surface is ready to clean. Follow the cure and care instructions for that film.
How do I tell which side of a window has a coating?
Check the glazing paperwork or ask the installer which face is treated. Film is applied to the pane. With factory low-E coatings, care depends on whether the coated face is exposed.
Can I clean windows with just water?
Water can lift light fingerprints from compatible glass with a clean microfibre cloth. If greasy marks remain, check which cleaning products the glass or film maker permits.
How should I wash microfibre cloths used on glass?
Follow the cloth’s care label and keep it away from grit. If a cloth starts smearing the glass, set it aside and use a clean one.
Can I use a window vac on tinted glass?
Check both the vacuum instructions and the tint maker’s care guide before using it on applied film. If approval is unclear, follow the film maker’s permitted hand-cleaning method.
Why do my outside windows look spotted again after rain?
Droplets can leave residue as they dry, especially when they pick up dirt already on the pane or in runoff. If spots survive a compatible wash, have them assessed.
Do coastal Sydney windows need cleaning more often?
They may if the site is exposed to salt spray. Check how quickly residue builds up and follow the maintenance instructions for your glass and frame finish.
Does a window-cleaning quote include flyscreens and tracks?
Westlink can include flyscreens and tracks when they’re specified in the agreed scope. Ask for both to be itemised if you need them cleaned alongside the glass.
Match the method to the pane, the dirt and what you can safely reach. For hard-to-reach windows or a larger job, share your access details with Westlink. Request a window-cleaning quote.
