Frequently Asked Questions: Window Cleaning

Yes, it is worth getting your windows cleaned regularly. Once a year is a good frequency. Maintaining your windows and keeping contaminant buildup at bay can help extend window life and prevent these contaminants from wearing down the structural integrity and strength of the glass.

You should avoid washing your windows on intensely hot or cold days and on sunny days when direct sunlight hits the windows.

The best day to clean windows, or the optimal window cleaning conditions, is during a cloudy day with minimal sunlight. Direct sunlight can lead to more streaks left behind because it causes the cleaning solution to evaporate faster. Also, consider that this job is best done in mild temperatures as extremely hot or cold weather can cause burns from hot glass or freezing of the cleaning solutions.

It’s good to clean your exterior windows once or twice a year depending on the level of pollutants and allergens in the air where you live. The more air pollution, the more often you should schedule window washing.

It’s best to clean interior windows first as these are likely cleaner than the exterior ones. You don’t want to bring more dirt and grime to your interior windows that will likely be lurking on the cleaning supplies after washing the exterior windows.
