How to wash windows properly without streaks?

Windows are the most popular way to let light into your home, and with good reason. Window washing in Chicago is necessary if you want your home or building's exterior to look its best. However, some people don't know how to do it well, leading to streaks and smears on the window. Luckily, there are some easy tips for accomplishing this with little difficulty. 

Few tasks are more tedious than washing windows, but it’s one of those jobs needed to get done if you want your house to look its best. Washing them properly can be hard work, though. Many people find it tricky to get the windows squeaky clean without streaks and struggle with all sorts of washing techniques that don't seem to work as they should. Even with the best tools and the most diligent approach, keeping the glass sparkling without leaving streaks can be tricky.  Here are some tips on how to wash windows properly and without streaks.

Tools for washing windows

The best thing you can do for a streak-free window washing is to use professional services. A window washing service such as Gutwin has the proper equipment, such as ladders, buckets, squeegees, soapy water, and rags. We also know how to wash your windows inside and out. You may not be able to reach all of the high places in your house or your building with a ladder. Plus, we will get into every nook and cranny with their ladders. One advantage of using professionals is that we take care of everything! 

When choosing a window washer, don't just focus only on cost because other things come into play when it comes time to wash windows.

The best time to wash your windows

The best time to wash your windows is on a cloudy day. This way, you're not going to get any sun glare while trying to clean. You should also avoid washing your windows when it's too hot or cold outside. If it's cold, the water could freeze before it dries. If it's hot, the water can evaporate before it dries, leaving streaky marks on your glass. Start at the top of the window frame when washing your windows, and work your way down towards the bottom. 

Recommendations on how to avoid streaks on the glass

The best way to avoid streaks on glass is by using a squeegee. When washing your windows, use a spray bottle with water first, then spray the window with cleaner or soap. You can also use a cloth dipped in the same mixture of cleaner or soap if you don't want to waste too much product. Using the squeegee, drag it across the surface in even strokes.  

To avoid streaking, wash one side of the window at a time using a long-handled squeegee or soft cloth. Take care not to wash one side while you're still working on another - this will cause streaking from the accumulated dirt and debris. Always use lukewarm water and non-abrasive soap. To avoid smudges and smears, apply enough soapy water for complete coverage, then gently scrub in circular motions with a soft cloth or sponge.

Once all the dirt has been removed, use a dry towel to polish up the window. After washing, close the blinds or curtains so they can dry before putting them back up in place.

Window washing - general rules 

You must never use a harsh or abrasive cleaner on your windows. The cleaner should be safe for the glass yet tough enough to break down the dirt. One of the best cleaners you can use is a non-abrasive window washer like Windex. You can also use vinegar mixed with water. Vinegar will leave a streak-free finish, but it may take more elbow grease than other washers. 

Which is better: to order a professional window washing or wash it yourself? 

You can hire a window washer or order a professional washing service for your residential property. The most important thing is to find someone who has the experience so that you get the best results. There is a lot of debate about which is best. Professional window washers can be more expensive than doing it yourself, but some people don't have the time to do it themselves or can’t achieve the perfection of absolutely clean windows. And there are safety risks, of course, especially if you use a ladder or try to reach windows using unsafe techniques . A professional window washing service is also great if you're planning on selling your house, it may be worth it just in case any buyers notice dirty windows. It also gives you peace of mind knowing that professionals will take care of all those hard-to-reach places. 

The step-by-step process

With a bit of know-how, you can get your windows sparkling wash for the winter. Follow these steps:  

1) Clean the window with a dry cloth first. Pay special attention to any dirt or grime. Wipe from top to bottom in one direction only. 

2) Apply an ammonia-free glass cleaner. While some people believe ammonia cleans well, we advise against using it because it leaves behind a film that's difficult to remove and makes the glass sticky if you try to wash them again too soon after the first time.

3) Wipe the glass with a dry microfiber cloth in straight lines, working from top to bottom.

4) When finished, check for streaks. If some are still visible, use the dry microfiber cloth again before going to another area. Repeat until all of the surfaces are streak free. 


A clean house is a home full of life. With that in mind, it's important to ensure your windows are clean, just as you would your floors or walls. The process isn't difficult; it just takes some preparation and elbow grease.  A professional window-washing company can do the job quickly, safely, and efficiently. The experts will not only wash your windows from top to bottom but also take care of any mold or mildew growth, replace your screens, and ensure that no pressure is put on your window frames.
