The Ideal Seasons for Window Cleaning. The best times to clean your windows are spring and fall. In the spring, you'll clear away winter's buildup of grime, salt, and debris. In the fall, window cleaning removes dirt, pollen, and dust before the winter months settle in.
The best time of year to wash windows is the fall and spring months. These times are optimal because, in most locations, they offer the best temperature to wash outside windows. Most pros agree that temperatures between 50 and 75 degrees Fahrenheit (10-24C) are best for effectively cleaning windows.
Standard Residential Schedule - 2 to 4 Times Per Year. Most homes benefit from thorough window cleaning every six months—once in spring and once in fall (This Old House, 2025). This baseline applies to Vancouver properties with moderate exposure to environmental factors.
On a sunny day, the lather will dry quickly, leaving persistent streaks and marks even after you've scrubbed and dried your windows. Window cleaning professionals recommend cleaning on a cloudy day.

Dish soap: Using a few drops of Dawn dish soap in your homemade window cleaner can help remove tough grime, which may be especially helpful when washing the exterior of your windows.
You should clean the exterior windows twice per year—in the fall and in the spring—and inside as often as needed. Homes with pets, dust, or lots of traffic may need more consistent cleaning. Aim for about once a month and see how that schedule works, then increase or decrease as needed.
However, ordinary tap water often contains minerals such as calcium and magnesium, which leave behind streaks or marks as it evaporates. Professional window cleaners generally rely on purified or deionised water.

Window Cleaning Tips
Whether using a squeegee or cloth, wash the window with horizontal passes on one side of the glass and vertical passes on the other. This makes it easier to identify whether any streaks are located on the interior or exterior side. Remove window screens before washing the windows, if possible.
When Should You Not Wash Windows? Avoid washing windows during precipitation, extreme cold (below 32°F), or when the weather forecast predicts rapid temperature drops that could cause the cleaning solution to freeze on the glass. Also, windy conditions can make outdoor cleaning dangerous and less effective.
Windows usually appear smeared after cleaning due to residual soap film, dirty cloths, or cleaning in direct sunlight.

Many Germans adhere religiously to the practice of Lüften ("ventilation"): At least twice each day, especially in the winter, they throw open all the windows to blast out stale air — as a matter of hygiene and good health. (Some people in the Low Countries and Scandinavia have a similar custom.)
10 hours before bed: No more caffeine. 3 hours before bed: No more food or alcohol. 2 hours before bed: No more work. 1 hour before bed: No more screen time (shut off all phones, TVs and computers).
