Window Cleaning in Melbourne: DIY Tips and When to Call the Pros

The difference between amateur window cleaning that leaves streaks and frustration, and genuinely clear, streak-free glass comes down to three things: the right tools, the right solution, and the right technique. Expensive products are not required. In fact, the simplest approach consistently produces the best results.

Start with a quality squeegee. This is the one tool worth investing in. A squeegee with a brass channel and a replaceable rubber blade, such as those made by Ettore or Unger, will outperform any amount of paper towel, newspaper, or spray-and-wipe product. For most residential windows, a twenty-five to thirty-five centimetre blade width is ideal. Wider blades cover more area but are harder to control on smaller panes. You also need a strip washer or applicator sleeve, which is the T-bar shaped tool with a fabric cover that you use to apply the cleaning solution.

The cleaning solution itself should be remarkably simple. Fill a bucket with clean warm water and add a small amount of dish soap, roughly half a teaspoon per litre. That is all you need. The soap acts as a surfactant, breaking the bond between dirt and glass so the squeegee can remove it cleanly. Too much soap creates suds that leave residue. Some professional window cleaners add a splash of methylated spirits to speed drying, but for most residential work, plain dish soap and water does the job perfectly.

The technique is where the real results come from. Dip your strip washer in the solution and wring it so it is damp but not dripping. Wash the entire window surface, working the washer across the glass to loosen all dirt, bird droppings, and environmental residue. Pay particular attention to the edges and corners where grime concentrates.

Now squeegee from the top. Place the rubber blade at the top left corner of the glass, angled slightly so water runs to the uncleaned side. Draw the squeegee across in a smooth, steady stroke. Wipe the blade with a clean, lint-free cloth. Place the blade at the top again, overlapping your previous stroke by about two centimetres, and draw across again. Continue working down the window in overlapping horizontal passes. After the final pass, use a dry microfibre cloth to wipe any remaining moisture from the edges and corners.

For smaller panes or windows with glazing bars, an S-pattern technique often works better than straight horizontal passes. Start at the top corner and draw the squeegee down in a continuous S-shaped motion, keeping the blade in contact with the glass throughout. This technique takes practice but is faster once mastered.

Clean the inside of your windows using the same technique. Interior glass accumulates fingerprints, cooking residue, and dust that dulls natural light. For interior work, use less solution on your strip washer to prevent dripping onto windowsills and floors. A terry cloth or microfibre cloth underneath the window catches any runoff.

Most people who struggle with window cleaning are making one or more of these common errors. Correcting them transforms the experience from frustrating to genuinely satisfying.

Cleaning in direct sunlight is the single most common cause of streaky windows. When sun hits wet glass, the cleaning solution dries before you can squeegee it off, leaving visible residue marks across the surface. In Melbourne, where a sunny morning can turn into cloud cover by afternoon and back again within the hour, timing your window cleaning requires some flexibility. Choose an overcast day, or work on the shaded side of the house first and move to the sunny side once the sun passes. Early morning and late afternoon provide the best conditions for exterior window cleaning.

Using too much cleaning product is the second most common mistake. Whether it is dish soap in your bucket or a commercial spray-and-wipe product, excessive cleaning solution leaves a film on the glass that is almost impossible to remove with a squeegee pass. The resulting haze is often worse than the dirt you started with. Less truly is more. A barely-there amount of dish soap in clean water is all you need.

The old trick of using newspaper to buff windows has not aged well. Modern newspaper inks are different from those used decades ago, and today's newsprint tends to leave ink residue on glass and window frames. Microfibre cloths have replaced newspaper entirely in professional window cleaning. A good quality, lint-free microfibre cloth absorbs moisture, picks up residue, and leaves no fibres behind on the glass.

Forgetting window tracks is an oversight that makes even perfectly clean glass look neglected. Window tracks accumulate dirt, dead insects, condensation residue, and fine debris that builds up over months. Dirty tracks are visible from inside and outside, and they can actually affect window operation by preventing smooth sliding. Clean tracks with a stiff brush to loosen debris, then vacuum out the loose material. Follow with a damp cloth dipped in your cleaning solution to wipe the tracks clean. For heavily soiled tracks, an old toothbrush works well for reaching into corners and grooves.

Neglecting window screens is another common oversight. Mesh fly screens accumulate dust and pollen that restrict airflow and transfer to the glass every time it rains or wind blows through the mesh. Remove screens annually, wash them with warm soapy water using a soft brush, rinse thoroughly, and allow them to dry completely before reinstalling. Clean screens allow more light and air through your windows and keep the glass cleaner for longer.

Finally, using abrasive materials on glass causes permanent damage. Steel wool, scouring pads, and even some stiff-bristled brushes can scratch glass surfaces. Once scratched, glass cannot be repaired, only replaced. For stubborn deposits like paint spots or adhesive residue, use a purpose-made glass scraper held at a shallow angle, and always work on a wet surface to lubricate the blade.

DIY window cleaning works well for single-storey homes with accessible windows. But several situations genuinely warrant professional help, and attempting them yourself creates unnecessary risk or delivers inferior results.

Multi-storey windows are the most obvious case for professional cleaning. Second and third-storey exterior windows cannot be safely reached from ground level, and ladder work on anything beyond a single storey falls outside what a homeowner should attempt without training and equipment. Professional window cleaners use water-fed poles, elevated work platforms, and rope access systems depending on the height and configuration. The safety risk of an untrained person on a tall ladder, particularly on Melbourne's occasionally gusty days, is simply not worth taking.

Large properties with twenty or more windows make professional cleaning a practical choice even when all windows are accessible. The time investment for DIY cleaning on a property of this size is substantial, often a full day's work, and a professional team with commercial equipment completes the job in a fraction of the time with consistently better results.

Hard water staining presents a cleaning challenge that most DIY methods cannot resolve. Melbourne's water supply varies in mineral content by suburb, and some areas, particularly in the western and northern suburbs, produce water with higher dissolved mineral content that leaves white, chalky deposits on glass over time. These deposits bond to the glass surface and resist conventional cleaning. Professional window cleaners have access to specialised acid-based treatments that dissolve mineral deposits without damaging the glass.

Post-construction window cleaning is a situation where professional help is not just advisable but essential. Construction dust, plaster residue, paint overspray, and adhesive from protective films can all damage glass if cleaned incorrectly. Rubbing a dry cloth over glass coated with fine plaster dust, for example, creates microscopic scratches that catch light and dull the glass permanently. Professional post-construction window cleaners know to flood the surface with water first, use specific chemical treatments for different types of construction residue, and employ techniques that remove contaminants without scratching.

Professional window cleaning in Melbourne typically costs five to fifteen dollars per window pane, depending on window size, accessibility, and whether the property requires special equipment. For a standard three-bedroom Melbourne home with fifteen to twenty windows inside and out, expect to pay between one hundred and fifty and three hundred dollars for a complete professional clean. Many homeowners find this a worthwhile investment two to three times per year, keeping windows in excellent condition between professional visits with occasional touch-ups on the interior glass.

Melbourne's climate creates distinct seasons for window cleaning, and timing your cleans to work with the weather rather than against it produces better results that last longer.

Spring, from September through November, is the most popular window cleaning season in Melbourne and for good reason. After months of winter rain that leaves mineral spots on glass, windblown debris, and the general environmental grime that accumulates on south and west-facing windows through the colder months, a thorough spring clean restores windows to their best just in time for longer days and increased natural light. Clean windows make a measurable difference to how much light enters your home, and as the days lengthen through spring, that difference is most noticeable.

However, timing within spring matters. Early September is ideal for interior windows and sheltered exterior windows. For fully exposed exterior glass, wait until after the initial burst of spring winds that Melbourne experiences through September and into October. Cleaning exterior windows during a windy stretch means dust and debris settle on wet glass within minutes of cleaning, undoing your work before it dries. Mid to late October, when Melbourne typically settles into more stable spring weather, is the sweet spot for exterior window cleaning.

Pollen is a consideration for homes in Melbourne's leafy suburbs. Properties in Hawthorn, Kew, Camberwell, and the Dandenong Ranges foothills are surrounded by mature trees that release significant pollen loads from September through December. If you live in these areas, schedule exterior window cleaning either before the main pollen release in early September or after the peak subsides in late November.

Autumn, from March through April, is the second ideal window cleaning period. Summer's dust, pollen residue, and insect activity leave windows looking tired by the end of February. A thorough clean in March or early April refreshes the glass before winter rain begins in earnest. Clean windows heading into winter also mean more natural light entering your home during the shorter days, which makes a genuine difference to the feel of indoor spaces through Melbourne's grey winter months.

Winter cleaning is generally unnecessary for exterior windows since rain provides a degree of natural cleaning. However, interior windows benefit from a wipe-down during winter because condensation, cooking steam, and the general enclosed nature of winter living deposits a film on interior glass that reduces light transmission. A quick squeegee of interior windows every four to six weeks through winter keeps the glass clear and your rooms brighter.

Summer window cleaning makes sense for properties hosting outdoor entertaining where clean windows form part of the aesthetic, or for homes near construction sites where summer dust accumulation is accelerated. Otherwise, the spring and autumn cleans typically keep windows in good condition through the warmer months.

Melbourne presents some unique window cleaning challenges that residents in other Australian cities do not face to the same degree.

The city's famous weather variability means you can clean exterior windows on a clear morning only to have rain arrive by afternoon. While light rain on freshly cleaned windows is not ideal, it does less damage than you might expect because the glass is already clean and the water runs off without leaving significant marks. Heavy rain with wind-driven dirt is another matter. Check the Bureau of Meteorology forecast before starting exterior windows and aim for a day with stable conditions through to evening.

Melbourne's proximity to Port Phillip Bay means properties in coastal suburbs like St Kilda, Brighton, Williamstown, and Altona experience salt spray deposits on windows, particularly after windy conditions. Salt residue is mildly corrosive and should not be left to build up over extended periods. Coastal properties benefit from more frequent exterior window cleaning, typically every two to three months, compared to the twice-yearly schedule sufficient for inland suburbs.

Urban construction is an ongoing reality across Melbourne's growth corridors and infill development areas. If your property is near a construction site, the fine dust generated by earthworks, concrete cutting, and demolition settles on windows rapidly and forms a stubborn film when combined with moisture. During nearby construction periods, a monthly wipe of accessible exterior windows prevents the buildup from bonding permanently to the glass.

For properties with floor-to-ceiling windows and glass balustrades, which are standard in Melbourne's newer apartment buildings across Southbank, Docklands, South Melbourne, and the CBD, professional cleaning is the practical choice. These large glass surfaces show every mark and are often at heights that preclude safe DIY access. Body corporate committees in these buildings typically arrange quarterly professional window cleaning for common areas, but individual apartment windows remain the resident's responsibility.

Whatever your property type and location across Melbourne, clean windows are one of the simplest ways to improve the feel of your home. Natural light affects mood, energy, and the perceived size of interior spaces. The difference between dull, film-covered glass and genuinely clean windows is something you notice every day, even if you cannot quite articulate why the room feels different.
