Knowing how to clean windows properly is one of those skills that separates a bright, polished home from one that always looks slightly dull. Clean windows let in more natural light, improve the appearance of your home from the street, and can even extend the life of the glass itself.
The problem is that most people end up with streaks, smudges, or lint marks after cleaning, which often looks worse than before they started.
This step by step guide shows you exactly how to clean windows without streaks, covers the best tools and solutions to use, and walks through the techniques professional window cleaning teams use every day.
Whether you are tackling a single kitchen window or the whole house, these methods deliver clear, spot free glass every time.
Why Windows Streak When You Clean Them
Before learning how to clean windows the right way, it helps to understand why streaks happen in the first place. Streaks are not a sign of bad effort. They usually come from one of five specific causes.
Cleaning in direct sunlight makes the solution evaporate before you can wipe it off, leaving marks behind. Using too much cleaner creates residue that dries into a cloudy film. Paper towels and cotton rags shed lint and push dirt around instead of lifting it. Dirty squeegee blades drag grime back across the glass. Hard water in your rinse leaves mineral spots as it dries.
Once you address these five factors, streak free windows become easy regardless of the cleaner or cloth you use.
| Streak Cause | Why It Happens | Simple Fix |
| Direct sunlight | Solution dries too fast | Clean on cloudy days or shaded sides |
| Too much cleaner | Excess residue | Use light, even sprays |
| Paper towels | Shed fibres | Switch to microfibre or newspaper |
| Dirty squeegee | Redeposits grime | Wipe blade between strokes |
| Hard water rinse | Mineral deposits | Use distilled water for final rinse |
What You Need Before You Start Cleaning Windows
Having the right tools makes cleaning windows faster and gives better results. You do not need expensive equipment, just a few basics.
Gather a bucket, a quality squeegee with a rubber blade, two microfibre cloths, a sponge or scrubber, a spray bottle, dish soap, white vinegar, and distilled water if your area has hard water. A step ladder is useful for taller windows, and a window cleaning pole helps with exterior glass on upper floors.
For commercial cleaning jobs or large homes, professionals add water fed poles, telescopic squeegees, and purified water systems that eliminate streaks automatically by removing minerals from the rinse water entirely.
How to Clean Windows With a DIY Solution
Store bought window cleaners work fine, but a homemade solution is cheaper, free of harsh chemicals, and often more effective. Here are three proven mixes.
Vinegar Based Cleaner Mix two cups of warm water, a quarter cup of white vinegar, and half a teaspoon of dish soap in a spray bottle. This solution cuts through grease, dust, and light mineral spots.
Dish Soap and Water For general cleaning, combine one teaspoon of dish soap with a bucket of warm water. This is what many professional window cleaners use on residential jobs.
Ammonia Based Cleaner For very greasy windows, especially kitchen glass, mix two tablespoons of ammonia with a litre of water. Never combine ammonia with bleach and always ventilate the area.
| Cleaning Solution | Best For | Cost per Litre |
| Vinegar and dish soap | General cleaning, light stains | Under $1 |
| Dish soap and water | Daily smudges, kids fingerprints | Under $0.50 |
| Ammonia and water | Heavy grease, kitchen windows | Around $2 |
| Commercial cleaner | Quick jobs, spot cleaning | $5 to $12 |
| Distilled water rinse | Hard water areas | $1.50 per bottle |
Whichever solution you choose, avoid mixing it too strong. More soap or vinegar does not equal cleaner glass. Light concentrations work better because they leave less residue.
How to Clean Windows Step by Step
Follow this sequence for perfect results on both interior and exterior windows.
Step 1: Dust the Frame and Sill First
Always start dry. Wipe down the window frame, sill, and tracks with a dry microfibre cloth or vacuum with a brush attachment. If you skip this step, dust turns to mud the moment water touches it.
Step 2: Mix and Apply Your Cleaning Solution
Fill your bucket with your chosen solution. Dip the sponge or scrubber, squeeze out excess liquid, and apply the cleaner to the glass using horizontal strokes. Work from top to bottom so drips run onto unwashed glass and not over your clean work.
For heavy grime, let the solution sit for one to two minutes to loosen dirt before wiping.
Step 3: Squeegee the Glass
This is where streak free results come from. Start at the top corner of the window and pull the squeegee straight down in a single continuous stroke. Wipe the blade with a microfibre cloth after each pass. For the next stroke, overlap the previous path by about two centimetres to avoid leaving lines between passes.
An alternative technique is the reverse S pattern, where you pull the squeegee in a snake motion from top to bottom without lifting it off the glass. This works well on wide windows.
Step 4: Wipe the Edges and Frame
Use a dry microfibre cloth to wipe any remaining drips along the window edges and frame. Check corners carefully, as these are the spots where streaks usually hide.
Step 5: Buff for a Final Polish
Run a clean, dry microfibre cloth lightly across the entire glass surface to remove any final smudges. Hold the cloth by the edges to avoid fingerprints on the glass.
How to Clean Windows Without a Squeegee
If you do not own a squeegee, two household items deliver surprisingly good results.
Newspaper has been a secret tool for decades. The dense ink and lint free fibres wipe glass clean without leaving streaks. Crumple a few sheets, spray the window with your cleaner, and wipe in circles. Follow with horizontal strokes on one side and vertical strokes on the other so you can tell which side has streaks.
Microfibre cloths work just as well when used properly. Use two cloths: one slightly damp with cleaner to wash, and one completely dry to buff. Fold each cloth into quarters so you have eight fresh surfaces to work with.
Avoid paper towels for cleaning windows. They shed fibres, scratch certain coated glass, and push streaks around instead of removing them.

How to Clean Windows Outside Your Home
Exterior windows collect far more dirt than interior glass. Rain, dust, pollen, bird droppings, and pollution all build up on outdoor panes. Cleaning them takes a slightly different approach.
Start by rinsing the window with a garden hose to remove loose dirt and debris. This prevents scratching during the wash. Apply your cleaning solution with a soft scrubber or sponge on a pole, working from the top down. For bug splatter or sticky residue, let the solution soak for a few minutes.
Squeegee the window using the same top to bottom technique as interior glass. For upper floor windows that cannot be reached safely from a ladder, a water fed pole with a soft brush head is the best option. These poles run purified water through the brush, meaning no squeegee is needed. The water dries spot free.
Never clean exterior windows during windy weather or when the glass is hot from direct sun. Early morning or late afternoon on an overcast day gives the best conditions.
How to Clean Different Types of Windows
Not all windows are the same. Different styles need slightly different approaches.
| Window Type | Special Consideration | Recommended Tool |
| Double hung | Clean upper and lower sashes separately | Squeegee with extension |
| Casement | Open fully to reach outer edge | Microfibre cloth and sponge |
| Sliding | Remove and vacuum tracks first | Soft brush plus cloth |
| Skylights | Safety is priority, consider professionals | Long handled pole |
| Stained glass | Avoid ammonia and harsh cleaners | Soft cloth with water only |
| Tinted glass | No ammonia, no abrasives | Soap and water solution |
| Louvre windows | Clean each slat individually | Narrow cloth or louvre tool |
| Frosted or obscure | Gentle circular wiping | Microfibre and mild soap |
For tinted or coated glass, always check manufacturer instructions before choosing a cleaner. Ammonia based products can damage some films and coatings permanently.
How Often Should You Clean Windows
How often windows need cleaning depends on your location, weather, and lifestyle. Here is a realistic schedule for most Australian homes.
| Location or Situation | Recommended Frequency |
| Coastal homes with salt spray | Every 4 to 6 weeks |
| Suburban homes | Every 2 to 3 months |
| Rural properties with dust | Every 6 to 8 weeks |
| City apartments | Every 1 to 2 months |
| Homes with pets and kids | Monthly spot cleans, quarterly full cleans |
| Commercial storefronts | Weekly or fortnightly |
| Office buildings | Monthly interior, quarterly exterior |
Regular cleaning prevents dirt from bonding to the glass. Research into building maintenance suggests that windows cleaned consistently last longer because contaminants like salt, sulphur, and hard water deposits can etch glass surfaces over time when left unaddressed.
Common Mistakes to Avoid When Cleaning Windows
- A few simple habits ruin otherwise good results. Watch out for these.
- Do not clean windows in direct sunlight. The heat dries cleaner before you can wipe it away.
- Do not use too much product. A light, even spray does more than a soaked glass panel.
- Do not reuse the same dirty cloth. Switch to a fresh microfibre side frequently.
- Do not skip the tracks and sills. Dirty frames spread grime back onto clean glass within days.
- Do not ignore the squeegee blade. Wipe it clean between every pass.
- Do not use rough scrubbers or scouring pads. They scratch glass and leave permanent marks.
For large jobs or commercial spaces where appearance affects business, it pays to read how clean windows can transform your business’s first impression before tackling it yourself.
Frequently Asked Questions
What is the best homemade window cleaner? A mix of two cups of water, a quarter cup of white vinegar, and half a teaspoon of dish soap works for most windows. It cuts through grime and leaves no residue when wiped properly.
Why do my windows still look streaky after cleaning? Streaks come from direct sunlight, too much cleaner, lint shedding cloths, or hard water in the rinse. Clean on a cloudy day, use microfibre cloths, and finish with a squeegee to eliminate streaks.
Can I use dish soap to clean windows? Yes. A small amount of dish soap in warm water is one of the most effective window cleaners available. Too much soap leaves residue, so keep the concentration light.
Is vinegar good for cleaning windows? White vinegar is excellent for windows. It dissolves mineral deposits, cuts through grease, and rinses clean without residue when used in the right concentration.
How do professionals clean windows without streaks? Professionals use a squeegee with overlapping strokes, wipe the blade between passes, and often use purified or distilled water to avoid hard water marks. They also clean frames and sills first to prevent contamination.
What is the best cloth for cleaning windows? Microfibre cloths are the best choice for both cleaning and buffing. Newspaper is a good backup option. Avoid paper towels and cotton rags, which leave lint behind.
Should I clean the inside or outside of windows first? Clean the outside first, because it usually has more dirt. Then clean the inside. This also helps you spot which side any remaining streaks are on.
How do I clean windows on high floors safely? For upper storey windows, use a water fed pole or hire a professional service. Never lean out of open windows or stand on unstable ladders. Professional window cleaners have the training and equipment to work safely at height.
Can cleaning windows damage them? Using abrasive scrubbers, harsh chemicals like ammonia on coated or tinted glass, or dirty tools can damage glass. Stick to soft cloths, appropriate cleaners, and clean tools to protect the surface.
How long does it take to clean windows in a house? A small home with 8 to 10 windows takes around 90 minutes. A larger home with 20 or more windows can take 3 to 4 hours depending on access, height, and the condition of the glass.
Clean windows change the entire feel of a room. Follow the steps above, avoid the common mistakes, and stick to a regular cleaning schedule. The difference between good and great window cleaning is almost always in the technique, not the product.
