You should clean your windows’ exterior at least twice a year. However, experts recommend 3 to 4 window cleaning sessions every year to maintain a good exterior.

In this article, we will talk about how often you should clean and wash windows during winter.
How Many Times Do You Need to Clean Exterior Windows Every Year?

Again, it would be best if you generally cleaned the exterior of your windows at least three times a year. However, the frequency of cleaning windows depends on the climate you live in.

Here are some tips on how often you should clean your windows based on specific factors:


If you live in places with average annual rainfall, you can get away with cleaning the exterior of your windows every six months.
For example, places like Austin, Texas or Cleveland, Ohio, have around 40 inches of annual rainfall. Therefore, you should get your windows cleaned twice a year if you live there.


Cities like Chicago have above-average rainfall. Therefore buildings such as apartment complexes and retail businesses in these areas require 3-4 window cleaning sessions annually.

Another thing to remember is that if you live in places with heavy rainfall, you should clean your windows before and after the rainy seasons. This ensures your windows remain in good shape and do not get damaged from residues from the rain.


Areas with significant industrial activity such as Chicagoland have a lot of factories as well as more pollutants in the air. As a result, it’s natural for your windows to get dirty easily in these locations. You will require three or more yearly window cleaning sessions in these types of areas.


DIY window washing is not recommended during the winter. Instead, professional window washers use freeze-resistant cleaning solutions to avoid damage from the cold.

If you have to wash your windows during the cold temperatures, it’s essential that you get help from the experts. However, the best time to clean your windows is during fall or spring.

Another crucial point to remember is the temperature of the water. Hot water can damage your property’s windows during winter, while cold water may freeze easily. Therefore, it’s better to leave this task to the professionals.


A general rule of thumb is to clean your windows at least twice a year. This is because the exterior of your property may not look appealing and also block essential sunlight if they are not clean enough. Moreover, professionally cleaned windows increase the value of your property. Therefore, to have a perfect exterior look, get three professional window cleaning appointments every year!
