The best way to clean windows for a streak-free finish

There’s nothing like seeing the warm sun entering your home through your windows. But if your windows are dusty and grimy, it could limit the air and light flow in your home. Regular cleaning can prevent this from happening. 

In this guide, you’ll get all the tips and techniques for cleaning large windows, inside windows, and more. No need to worry about leaving scratches and dust all over!

Cleaning different types of home windows 

The steps and cleaning materials in this guide apply to most windows, whether you’re wondering how to clean balcony windows, picture windows, or window screens. Still, it’s vital to check what kind of windows you have at home to prepare the right cleaning supplies. After all, windows aren’t just basic squares or rectangles made of glass; They come in different sizes, shapes, and materials. 

Window cleaning supplies

Like any cleaning job at home, you’ll need a few things to get it done. Depending on how many windows you plan to clean in one day, make sure you have enough cleaning supplies. This way, you don’t reuse old ones and spread bacteria and grime on other windows.

• Squeegee - A smooth, flat rubber-edged blade set on a metal handle that scrapes dirt off the glass

• T-bar window washer - Similar in appearance to a squeegee, this one has a longer handle and cloth head (usually microfibre), so it absorbs the liquid on the window without completely removing it.

• Soft-bristled brush - The gentle version of a bathroom scrubbing brush. This one can help break down dirt and grime without scratching the glass.

• Buckets - These will catch dirty window grime, so you can properly get rid of them later.

• Lint-free cloths or towels - This type of cloth prevents streak marks when you wipe down a window.

• Rubber gloves - To protect your hands from drying cleaning solutions

• Window cleaner or dishwashing liquid - Opt for streak-free window cleaners. If you can’t find one, mix 8 litres (2 gallons) of water with one teaspoon of dishwashing liquid to make a DIY window cleaning solution. 

• A ladder - If the windows in your home are high, you’re going to need one

What is the best way to clean windows without streaking?

Pick a cloudy (not rainy) day. You might think a warm, sunny day is ideal for window cleaning, but it’s the opposite. The hot temps can lead to streaks since they can dry the cleaning solution faster and leave unwanted water marks. Therefore, cleaning on a cloudy day, especially in spring or fall, is the best way to clean inside windows, glass windows, or any other type of window.

How to clean windows from the inside and outside

If you always have to search for how to clean windows without streaking, we’ve got the answer for you in four easy steps!

1. Clean screens first

Cleaning window screens is easy, which is why it’s best if you finish them first before moving on to the glass. 

Here’s how to clean window screens: 

• Remove the screens from their slots. 

• Next, pressure-wash them with water before spraying them with a cleaning solution.

• Once the screen is saturated in solution, run the hose or pressure washer over it and leave it out to dry before placing it back in the window slot.
  
  

2. Brush off the dust on the window and windowsill

Using a soft-bristled brush, gently wipe down the dirt, dust, and grime on your windows. Make sure you’re going in one direction to avoid spreading it everywhere. 

Then, proceed with cleaning your windows with a hose if you’re cleaning from the outside. If the grime is thick, use a long mop to dislodge the dirt.

Tip: After cleaning the dust off your windowsill, you can apply a layer of floor wax to prevent future dirt buildup.

3. Mist your window with your cleaning solution

If your window is small, apply enough solution to the whole area. But if the window is big, apply it in sections to avoid having the solution dry on the glass. 

Whether using a store-bought window cleaner, a professional window cleaning solution, or a DIY solution, you must not put too much, as the bubbles and water droplets can leave marks.
 

4. Wipe from top to bottom with a lint-free cloth or squeegee

Once your window is wet with solution, wipe it clean in one direction—top to bottom. If you’re using a towel, make sure it’s lint-free or microfibre so it won’t leave mini shreds of lint. 

Cleaning your window from the outside? You can use a squeegee or T-bar window washer! If you opt for a squeegee, make sure you wipe it clean after every pass on your window.

Common window cleaning mistakes

If cleaning windows wasn’t your favourite thing to do before, it’s probably because you made one of these mistakes—don’t fall for these next time!

Choosing a sunny day to clean windows

As mentioned above, when cleaning windows, you want to avoid overly hot and sunny days because the temperatures can quickly dry your solution and water, leading to streaks.

Using old cotton rags to wipe windows

They can spread lint everywhere. Your best bet is always a lint-free cloth like a microfibre towel since it’s super absorbent, reusable, and leaves glass shine- and streak-free.

Cleaning ALL windows in one day

The world won’t end if you don’t clean all your windows in one day. You can do it one room at a time. If you live in a less-polluted neighbourhood, you can opt to clean your windows once or twice a year. But if you live in the city or near a major road, you might have to clean them regularly, say, once a month.
 

Using a squeegee for indoor window cleaning

A squeegee doesn’t absorb water, so where does it go when you wipe it down? On the floor. This is why squeegees are best for outside window cleaning. But if you insist on using one, make sure you have a bucket underneath it to catch whatever liquid it moves.
