It's Not Just Windows
While cedar pollen's yellow-green film on windows gets the most attention, the same fine pollen settles onto driveways, patio furniture, roofs, and pool water throughout the winter cedar season, contributing to a general layer of grime across the whole property.
Why It's Different From Spring Pollen
Cedar pollen tends to be heavier and stickier than spring oak or grass pollen, meaning it can bind to surfaces more persistently and, when combined with winter dampness, can contribute to mildew growth in shaded or poorly-drained areas.
Timing Cleaning Around Cedar Season
Scheduling exterior cleaning right after peak cedar season (typically by late February) addresses the accumulated pollen film across windows, patio furniture, and hardscape before spring pollen season adds another layer on top.
