A List of Things That Can Make Your Windows Dirty Again

Some business owners need to have their exterior windows cleaned more often than others. Many must adjust their window cleaning schedules regularly as the outdoor weather and other environmental factors change. Keep reading to learn about factors that typically make your windows dirty.

Air Pollution

Outdoor air pollution can cause a build-up of particles on your windows over time. This is especially true for businesses located in areas with high levels of pollution. Your windows may become dirty more quickly as a result.

Air pollution is typically worse in the winter because cold, dry air traps pollution particles and doesn’t allow them to blow away. Additionally, there is less rain during the winter, which would normally rinse pollution particles out of the air. Windows can become covered with airborne pollutants more quickly during the winter months.

Cleaning Residue

If you use a window cleaner that leaves behind a streaky residue, your windows will get dirty more quickly. While windows typically repel dust and dirt particles, the residue from window cleaner can make them sticky, so that dirt and pollution particles will stick to them.

If your windows get dirtier more quickly after you’ve switched window cleaning solutions, it’s probably because the new solution leaves residue. Switch to a formula that doesn’t leave streaks.

Hard Water

Rinsing your windows with hard water can leave spots and streaks on the glass because the minerals in the water will not evaporate completely as the water dries. If you live in an area with hard water, it is best to avoid rinsing your windows with a hose and stick to professional window cleanings instead.

Water that contains a high concentration of minerals is known as hard water. When this water evaporates, it can leave behind a chalky residue on surfaces like windows. Hard water is relatively common, and it’s not unusual for tap water to contain 200 to 500 parts per million of mineral solids. This means that even if the water looks clear, it can still leave a film on your windows after you rinse them.


Wind can blow dirt and dust around, making it settle on things like window exteriors and making them look dirty. Windows that are in direct contact with the wind will become contaminated more quickly than those that are not. This is because the wind carries debris and dirt that can then stick to the window.

Some seasons are windier than others, which can cause more dirt and dust to build up on windows. Spring is usually the windiest season, so windows may need to be cleaned more often in March and April.


There are many benefits to having clean windows, both for your business and for the environment. Clean windows allow natural light to enter your building, reducing energy costs. In addition, clean windows create a better first impression for customers and clients.

When it comes to window cleaning, it is best to hire a professional. While you can clean your windows yourself, professionals have the experience and equipment to do a thorough job. In addition, professionals can often get your windows cleaner in a shorter amount of time.

If you are looking for a window cleaning company, research their reputation and experience. You should also ask for references and get a free estimate before hiring anyone. By taking the time to find a reputable and experienced window cleaning company, you can be sure that your windows will be clean and sparkling in no time.
