Post Rainy Season Window Cleaning Checklist for San Clemente
The rainy season here typically runs from late fall through early spring. California tracks this as the water year, which officially runs from October 1 through the following September 30, according to the state’s Office of Environmental Health Hazard Assessment. Orange County averages around 12 to 13 inches of rain a year, most of it falling in a few concentrated months. Once the storms taper off, windows often need more attention than people expect.
What Rain Actually Leaves Behind
Rain itself is fairly clean, but it rarely falls on clean surfaces. As it runs down glass, it picks up dust, pollen, and debris sitting on the window and the roofline above it. When that mix dries, it often leaves behind faint spots and streaks that look worse than the dust ever did on its own.
Lower windows near landscaped areas can also collect mud splash during heavy storms, especially on ground floor glass close to sprinkler zones or exposed dirt.
Where to Check First
- Window tracks. Storm runoff often carries dirt and small debris into tracks, where it can sit and trap moisture.
- Weep holes. These small drainage gaps at the base of a window frame can clog with debris, which affects how well future rain drains away.
- Ground floor glass. Mud splash from heavy rain is common here, especially on homes with landscaping close to the windows.
- Screens. Dust that rain pushes into the mesh can dry into a dull film that a light rinse alone will not fully clear.
- Hillside and sloped lots. Homes in areas like Talega or Forster Ranch often see more runoff moving across exterior surfaces during a strong storm.
Checklist for After the Storms Pass
| Area | What to Look For | Action |
|---|---|---|
| Window tracks | Dirt, leaves, small debris | Clear out and wipe down |
| Weep holes | Blockages at the base of the frame | Clear gently with a soft tool |
| Ground floor glass | Mud splash or dried spotting | Full exterior wash |
| Screens | Dull film or trapped dust | Rinse or remove for a deeper clean |
| Upper level windows | Mineral spotting from dried runoff | Professional cleaning if hard to reach safely |
Why Timing Matters
Cleaning too early, while more storms are still likely, often means redoing the work within a few weeks. Most homeowners get the best result by waiting until the wet pattern has clearly broken before scheduling a full cleaning. This is usually sometime in spring, though the exact timing shifts year to year depending on how the season plays out.
Frequently Asked Questions
Does rainwater clean windows on its own?
Not fully. Rain often just relocates dust and debris rather than removing it, and it can leave mineral spots behind as it dries.
How do I know if my weep holes are blocked?
Standing water inside the window track after rain, or water that seems slow to drain, are both signs a weep hole may need clearing.
Is it worth waiting until the season fully ends to clean windows?
Usually, yes. Cleaning between storms often means the glass picks up new spotting again before the wet pattern is finished for the year.
