How to clean outside windows is a common question for many homeowners. If you’ve ever looked out of your home’s windows and noticed streaks, dust, rain marks, or patches of grime blocking your view, you’re definitely not alone.

Why Learning How to Clean Outside Windows Matters
Before getting into methods and ingredients, it helps to understand why learning how to clean outside windows is worth the effort.
Cleaner windows improve natural lighting
Dirty windows can block sunlight, making your rooms look dim and gloomy. Once clean, you’ll notice:
- brighter rooms
- clearer views
- a fresher atmosphere inside your home
Natural light can even improve mood, focus, and productivity.
Clean outside windows improve kerb appeal
Windows are one of the first things people notice when they look at a house. Clean exterior glass can make your:
- home look newer
- property appear more well maintained
- exterior feel fresher and brighter
If you’re renting, hosting guests, or planning to sell, knowing how to clean outside windows is a small effort that creates a big visual difference.
Regular cleaning protects your windows
Dirt and mineral deposits don’t just look bad — they can also damage your glass over time. Grime build-up may cause:
- water stains
- etched or cloudy glass
- frame corrosion
- reduced window lifespan
By cleaning your outside windows regularly, you’re not just improving their appearance — you’re also preventing long-term wear and damage.
Why Use Simple Household Items Instead of Store-Bought Cleaners?
A big reason people search for how to clean outside windows using simple household items is that store-bought cleaning sprays can be:
- expensive
- harsh on the skin
- bad for the environment
- full of chemicals
Household ingredients are often:
- cheap
- easy to find
- eco-friendly
- safe when used properly
Plus, homemade cleaning mixtures can work just as well — and sometimes even better — especially when tackling stubborn outdoor grime.
Let’s take a look at some of the most useful household items for how to clean outside windows effectively.
Household Items You Can Use to Clean Outside Windows
If you want to learn how to clean outside windows without special tools, start by gathering a few everyday items. You don’t need everything on this list — simply choose the items that best suit your situation and the type of window surface.
Common household cleaning ingredients
- white vinegar
- washing-up liquid or mild liquid detergent
- baking soda
- lemon juice
- warm water
- rubbing alcohol (optional, for extra shine)
Useful cleaning tools
- microfibre cloths
- soft sponges
- old T-shirts or cotton towels
- squeegee
- spray bottle
- bucket
- soft-bristle brush
- old toothbrush (for corners and edges)
For hard-to-reach outside windows
If your windows are higher up, always prioritise safety. Rather than leaning out dangerously, consider using:
- a long-handled squeegee
- a long window mop
- a garden hose (for a gentle rinse only)
If a window is too high or unsafe to reach, it’s always best to ask an adult for help or hire a professional cleaner rather than risk climbing on unstable surfaces.
Preparing Before You Clean Outside Windows
Before jumping straight into cleaning, proper preparation makes the process much easier and helps prevent streaks.
Step 1: Check the weather
Believe it or not, sunny days aren’t always the best time to clean exterior windows. Direct sunlight causes water and cleaning solutions to dry too quickly, which can leave streaks behind.
The best conditions for learning how to clean outside windows are when:
- the weather is cool
- there is shade over the window
- it’s early morning or late afternoon
Cloudy days are ideal for achieving streak-free results.
Step 2: Remove loose dirt and debris
Before applying any cleaning solution, gently rinse or wipe away loose dirt so it doesn’t smear across the glass.
You can:
- lightly spray the window with a hose
- dust using a dry cloth or soft brush
- wipe the window frames first
This helps prevent muddy streaks and reduces the risk of scratching the glass.
Step 3: Clear the window area
Move away:
- flower pots
- furniture
- decorations
- any obstacles near the window
This gives you enough space to move comfortably and reach the edges safely while learning how to clean outside windows the right way.
Best Homemade Cleaning Solutions for Outside Windows
Now let’s explore several highly effective household cleaning mixtures. These natural cleaners are excellent alternatives to chemical products and are commonly used in DIY window care.

Mix both ingredients and shake gently.
Why it works:
Vinegar helps dissolve:
- mineral deposits
- water stains
- grime
- streaks
It also leaves the glass looking clear and shiny.
2. Dish Soap and Water Solution
If your outside windows are especially dirty or greasy, dish soap is very effective.
You’ll need:
- a few drops of washing-up liquid
- a bucket of warm water
Dip a sponge or cloth into the soapy water and gently scrub the glass.
Why it works:
Dish soap helps remove:
- grease residue

- insect marks
This solution is particularly helpful for kitchen windows that may collect cooking residue.
3. Baking Soda Paste for Stubborn Stains
Some marks can be difficult to remove. In these cases, baking soda works well.
You’ll need:

- a small amount of water
Mix until it forms a light paste. Use it to gently scrub:
- bird droppings
- hard water spots
- thick grime patches
Avoid scrubbing too hard, and always rinse thoroughly afterwards.
4. Lemon Juice Shine Solution
Lemon juice helps add an extra sparkle to your windows.
You’ll need:
- 2 tablespoons of lemon juice

Spray lightly after cleaning and wipe with a microfibre cloth for a streak-free shine.
Step-by-Step Guide: How to Clean Outside Windows Using Household Items
Now that you’ve learned about the right tools and cleaning solutions, let’s walk through exactly how to clean outside windows from start to finish. This step-by-step method is simple, safe, and budget-friendly.
Step 1: Rinse the window
Before applying any cleaner:
- gently rinse the window with water

This prevents scratching and helps the cleaning solution work more effectively.

Step 3: Gently scrub the glass
Use:

Move in circular motions to lift stubborn dirt.
Avoid using:
- rough scouring pads
- metal brushes
- abrasive tools
These can permanently scratch the glass.
Step 4: Rinse again
Once scrubbing is complete, rinse away:

Any leftover cleaner can cause streaks, so thorough rinsing is essential.
Step 5: Use a squeegee for a streak-free finish
A squeegee is one of the best tools for anyone learning how to clean outside windows without leaving streaks.
To use it properly:
- start at the top of the window
- pull downwards in straight lines
- wipe the blade between each stroke
This removes water evenly and prevents marks.
Step 6: Dry the remaining edges
Use a microfibre cloth or cotton towel to:
- wipe the corners
- dry the window frame
- remove any remaining droplets
This final step leaves your windows looking clear, polished, and professional.
How to Clean Outside Windows with Screens Installed
Many homes have mesh window screens that collect dust and dirt. If you clean the glass but ignore the screens, your windows can still look dirty. Knowing how to clean outside windows properly includes taking care of the screens as well.

If your screens are removable
Carefully remove the screens and:

If your screens are fixed
If the screens cannot be removed, you can:
- brush them gently
- wipe with a damp cloth
- use a handheld vacuum on low suction
Even a quick clean can make a noticeable difference and help your windows look much clearer.
