Streak-free windows instantly make your home feel brighter, cleaner and more welcoming, but getting that crystal-clear finish can be tricky if you do not know the right methods.
In this guide, we will walk you through everything you need to know before you start, including how often to clean your windows, the best weather conditions and key safety tips. You will see exactly which tools and supplies you need, plus the most effective cleaning solutions, from classic dish soap mixes to vinegar, citric acid, black tea, alcohol-based cleaners and commercial sprays.
We will then share step-by-step methods for cleaning interior and exterior windows, how to use a window vac, steam cleaner and even newspaper, and when it is smarter to hire professional window cleaning services in Dubai and Sharjah.
2. Things to Know Before You Start Cleaning Windows
For streak-free results that last, plan to clean your windows on a regular schedule and under the right conditions, while always prioritizing safety.
As a general rule, interior glass benefits from a light clean roughly every two months to remove fingerprints, dust and indoor grime, while exterior panes should be washed at least twice a year, with more frequent cleaning—about every two months—if you live near a busy road, in a high-pollution area or where pollen levels are high.
Whenever you clean, avoid working in direct sunlight or on very hot days, because the glass heats up and causes your cleaning solution to dry too quickly, which almost guarantees streaks and water spots. Instead, choose a cool, overcast, dry day, or work in the early morning or late afternoon so the glass stays slightly cooler and you have time to wipe the solution away before it evaporates.
Before you start, think about safety: if you need a ladder, make sure it’s on a firm, level surface, keep three points of contact as you climb, and use extension poles or long-handled tools wherever possible so you don’t have to overreach. Indoors, protect your floors, walls and nearby furniture by laying down towels or a canvas drop cloth to catch drips and prevent slips.
For upper stories, very large windows or any hard-to-reach areas where you’d need to lean dangerously or balance at height, it’s wiser to call a professional window cleaner, both to protect your own safety and to avoid accidental damage to the glass, frames or surrounding surfaces.

Best Cleaning Solutions to Use For Window Cleaning
1. Classic Dish Soap & Water Mix
A simple mix of dish soap and water is often all you need for clean, streak-free windows. Start by filling a bucket with about 2 to 3 gallons of warm water, then add a small “10-second squeeze” or a few small squirts of a regular, non-lotion dish soap and stir gently to combine.
This mild solution creates enough cleaning power to cut through everyday dust, light grease and general outdoor grime without leaving a heavy, streaky film on the glass.
It works especially well on exterior windows that are dirty from rain, pollen or road dust, and it is also safe for most standard interior glass when you just need a regular refresh rather than a deep clean.
2. Vinegar-Based DIY Cleaners
Vinegar-based DIY cleaners are a powerful, low-cost option for keeping windows clear of everyday dirt and light grease. To make a simple solution, mix equal parts distilled white vinegar and water in a spray bottle and shake gently so the liquids combine.
When sprayed onto glass, the mild acidity in vinegar helps break down fingerprints, light oily residue and dull, cloudy films that regular water alone cannot remove. This makes it ideal for routine cleaning on both interior and exterior panes.
However, you should always protect nearby stone sills, such as marble or limestone, with a cloth or plastic covering, because repeated contact with acidic vinegar can etch or damage these delicate surfaces.
3. Citric Acid Solutions
Citric acid solutions are another effective, natural way to clean windows and tackle light limescale at the same time. To make a simple mix, add 2 to 3 tablespoons of citric acid powder to about 2 pints of warm water and stir until the crystals dissolve completely.
Dip a microfiber cloth into the solution, wring it out well and then wipe the glass in smooth, overlapping strokes. The gentle acidity helps dissolve mineral spots and dull films, leaving the pane clear and bright.
As with vinegar, avoid letting the solution sit on delicate stone sills to prevent possible surface damage.
4. Black Tea With Lemon
Black tea with lemon is an unusual but effective DIY window cleaner, especially in homes where glass is coated with cooking oils or nicotine. Start by brewing a large, very strong cup of black tea, then pour it into a bucket with about a gallon of warm water and add the juice of half a lemon.
Stir well and dip a microfiber cloth into the mixture, wringing it out before wiping the glass. The tannins in the tea help break down oily, yellowish films, while the citric acid in the lemon gently softens limescale, leaving windows clearer and easier to polish streak-free.
5. Alcohol-Based Mixes
Alcohol-based mixes are especially useful when you need to tackle stubborn spots and want the glass to dry quickly with minimal streaks. To make a simple cleaner, add a small splash of rubbing alcohol or methylated spirits to a spray bottle filled mostly with water and, if you like, a little vinegar.
Shake gently to combine the liquids. Spray the solution directly onto marks such as sticky residue, fingerprints or greasy patches and wipe with a clean microfiber cloth. The alcohol helps dissolve the grime and then evaporates fast, reducing the chance of water spots or cloudy streaks.
6. Commercial Glass Cleaners
Commercial glass cleaners are one of the best window cleaning solutions when your windows are very dirty, you want a fast result or you prefer a ready-made product instead of mixing your own solution. You can choose a standard store-bought spray or a concentrated window cleaner that you dilute with water according to the label.
Many of these formulas leave a very light protective film on the glass, which helps rain and dirt slide off more easily so the windows stay cleaner for longer. However, you should always use them sparingly, because too much product can build up into a greasy layer that actually attracts dust and causes streaks.
Step-by-Step: How to Clean Interior Windows Without Streaks
Lay down drop cloths or towels under the windows and move or cover any nearby furniture to protect it from drips.
Brush or vacuum loose dirt, dust and cobwebs from the window tracks, sills and corners.
Wipe the frames with a non-abrasive cleaner, using appropriate care for the material (gentle products for wood, standard mild cleaners for vinyl or aluminum).
Prepare your chosen window cleaning solution in a bucket or spray bottle.
Apply the solution to the glass with a sponge or scrubber, working in smooth S-shaped, up-and-down and side-to-side motions so you cover the entire surface evenly.
Make sure the glass stays evenly wet so the squeegee can glide smoothly without skipping or dragging.
Use the squeegee starting from a dry edge at the top of the window, pulling in straight horizontal or vertical strokes while holding the blade at a slight angle.
Wipe the rubber blade with a clean cloth after every pass to prevent streaks and drips.
Dry the edges, corners and any remaining moisture on the glass with a clean microfiber or other lint-free cloth.
If needed, lightly polish the glass with crumpled newspaper for extra shine, taking care not to touch or stain painted or delicate frames.
Step-by-Step: How to Clean Exterior Windows Without Streaks
Remove the insect screens and inspect them for any torn or damaged mesh that may need repair or replacement.
Wash the screens with mild soapy water and a soft brush, then rinse them thoroughly and let them dry completely (and store them over winter in cold climates).
Brush loose dust, cobwebs and debris from the exterior window frames and sills.
Wipe the frames with a suitable, non-abrasive cleaner, avoiding harsh chemicals that could damage paint, sealants or special coatings.
Mix a slightly stronger exterior window cleaning solution to cut through road film, pollen and greasy build-up on the glass.
Wash the glass from top to bottom so dirty water does not run over areas you have already cleaned, scrubbing a second time if the windows are very dirty.
For large, ground-floor windows, use the bucket method: dip your scrubber or sponge, wring out the excess, scrub the glass and immediately follow with a squeegee.
Work in small sections so the cleaning solution does not dry on the glass before you can squeegee it away.
For upper-story or hard-to-reach windows, use extension poles with long-handled scrubbers and squeegees so you can work safely from a stable position.
Hire a professional window cleaner if the exterior windows remain difficult or dangerous to access, especially on multi-story homes or over uneven ground.
How to Clean Windows With a Window Vac
A window vac makes window cleaning fast, tidy and streak-free, but you need to prepare it properly and use it in the right sequence. Before you start, always check the squeegee blade for signs of wear such as nicks, waves or hardened edges, because any uneven surface will leave visible lines on the glass.
If the blade is double-sided, rotate it to a fresh edge, or replace it if both sides are worn. Then remove dust and tiny grit from the rubber by pulling it gently across a damp microfiber cloth or the cleaning pad so the blade is perfectly clean.
Next, spray your window with a suitable cleaning solution and loosen the dirt using a microfiber pad or sponge. As soon as the glass is evenly wet, place the window vac at the top of the pane and pull it down in straight, slightly overlapping strokes, wiping the blade with a cloth after each pass.
This combination of clean rubber, correct technique and steady, top-to-bottom movement allows the window vac to remove water efficiently and leave your windows clear and streak-free.
How to Clean Windows With a Steam Cleaner
A steam cleaner is a great way to deep-clean windows while reducing streaks, as long as you follow the right steps. Start by filling the steam cleaner with demineralized or distilled water, because it contains no minerals that could dry on the glass and leave spots. Attach the appropriate window or hand nozzle with a microfiber cover, then slowly steam the glass, moving the nozzle in overlapping passes to loosen dirt, grease and old cleaner residue.
Once the surface is thoroughly steamed and the grime has been lifted, immediately remove the moisture with a squeegee or a compatible window vac, working from top to bottom in straight, slightly overlapping strokes.
Wipe the rubber blade or suction lip after each pass so you are not dragging dirty water back across the glass. Because the steam is demineralized, it evaporates cleanly and helps prevent streaks or chalky marks, leaving the window clear and refreshed with minimal chemical use.
How to Clean Windows With Newspaper
Cleaning windows with newspaper is best used as a final drying and polishing step rather than the main cleaning method. First, wash your windows with your preferred solution and wipe most of the moisture away using a squeegee or a clean microfiber cloth so the glass is only slightly damp.
Then loosely crumple a few sheets of black-and-white newspaper into soft balls and gently buff the glass in circular or vertical strokes, focusing on any faint streaks or cloudy patches. The paper helps absorb remaining moisture and can leave a crisp, clear shine.
Avoid rubbing newspaper directly on wet, dripping glass because it will tear and shed, and keep it away from painted or light-colored frames where the ink could smudge or stain the surface.
