Getting your windows truly clean — not just smear-free but crystal clear — is more of a skill than it looks. After years of hands-on experience cleaning windows across Dubai, I've put together the 10 practical tips that make the biggest difference. Whether you're tackling indoor glass or exterior panes coated in desert dust, these techniques will help you get professional results every time.
Choose a Cloudy Day or Clean in Shade
In Dubai, direct sunlight is one of the biggest enemies of a streak-free finish. When the glass is hot, your cleaning solution evaporates almost instantly, leaving behind dried residue and stubborn streaks before you even reach for the squeegee. Always clean windows in the early morning, late afternoon, or on an overcast day when the glass is cool to the touch.
Use Distilled Water in Your Cleaning Mix
Dubai's tap water has a high mineral content. When this water dries on glass, it leaves white mineral deposits and water spots that are very difficult to remove. Mixing your cleaning solution with distilled or purified water prevents these spots from forming in the first place, giving you a consistently clear, spotless finish with far less effort.
Make the Right Cleaning Solution
You don't need expensive chemical cleaners. A professional-grade solution is simply warm water with two to three drops of mild dish soap. For windows with mineral deposits or light grime, add a small splash of white vinegar (1:2 ratio with water). Avoid using too much soap — excessive suds leave a cloudy film that's harder to remove than the original dirt.
Always Clean Frames and Sills First
This is a rule every professional follows: never clean the glass before the frames and sills. If you clean the glass first, you'll just dirty it again when you wipe down the surrounding frame. Vacuum or brush out the window tracks and sills to remove dry sand and dust, then wipe frames with a damp microfiber cloth before touching the glass.
Invest in a Quality Squeegee
A good squeegee is the single most important tool for streak-free windows. Choose one with a soft, high-quality rubber blade (10–18 inches depending on your window size). Check the blade regularly for nicks or chips — even a small imperfection in the rubber will leave a streak line on every pass. Replace blades when they show any signs of wear.
Master the S-Pattern Squeegee Technique
The S-pattern (or snake technique) is what separates professional results from amateur ones. Instead of pulling the squeegee in straight lines, you move it in a continuous overlapping "S" across the glass. This keeps the blade in contact with the surface the entire time and channels dirty water away from the cleaned section. Wipe the blade with a clean dry cloth after every pass to avoid re-depositing dirt.
Work from Top to Bottom
Always start at the top of the window and work downward. Gravity means water and cleaning solution will run down as you work. If you clean the bottom first, dirty water will drip onto your already-clean sections, forcing you to re-clean. This top-to-bottom rule applies to both the scrubbing/washing stage and the squeegee stage.
Use Microfiber Cloths — Never Paper Towels
Paper towels and newspaper leave behind tiny fibres and lint on the glass. Microfiber cloths are lint-free and highly absorbent, making them perfect for detailing the edges, corners, and bottom rail of the window after you've finished squeegeeing. Keep several clean, dry microfiber cloths on hand — a dirty cloth will smear more than it cleans.
Dry-Dust Before You Wet-Clean
In Dubai, windows accumulate layers of fine desert dust and sand. If you apply liquid directly to a dusty window, you're simply turning that dust into a muddy paste that smears across the glass. Before using any cleaning solution, always dry-dust the glass with a clean, dry brush or vacuum attachment to remove loose particles first.
Know When to Call a Professional
Some windows — particularly high-rise exterior panes, skylights, or heavily stained glass — require professional-grade equipment and safety training. Never lean out of windows or overextend on a ladder to reach difficult panes. Shades Cleaning Company's trained window cleaning specialists have the tools, ropes, and platforms to safely clean any window at any height, delivering results that simply aren't achievable with DIY methods.
