Why Dirty Window Screens Make Clean Glass Look Dull

Here is why screens matter more than most people think, and how to keep them from undoing a fresh clean.

What builds up in a window screen?

Screens are made to catch things, and they do. Over a season they collect:

• Pollen, especially in spring when trees and grass release it across Long Island.
• Fine dust from roads, yard work, and nearby construction.
• Salt film on homes close to the bays and the ocean.
• Cobwebs, insects, and seed fluff caught in the corners of the frame.

From a distance, that buildup looks like a gray haze over the window. Up close, the mesh may look clogged or yellow. Because the screen sits a short distance from the glass, you look through both every time you look outside.

Why does a clean window look dirty again so quickly?

If you wash the glass and leave a dirty screen in place, two things happen. First, the haze in the screen still blocks some light and dulls the view, so the window never looks quite clear. Second, opening and closing the window, a breeze, or a rainstorm shakes dust out of the mesh and onto the glass you just cleaned.

That is why many homeowners feel a window cleaning did not last when the real culprit was the screen.

How often should screens be cleaned?

For most homes, once a year is a good baseline, ideally in spring before you start opening windows. Consider washing them more often if:

• Your home is near the water and you see salt haze.
• The house sits under large trees that drop pollen and debris.
• Someone in the house has allergies and you open windows often.
• You can see a yellow or gray film on the mesh.

A simple test is to tap the screen lightly from inside. If a puff of dust comes out, it is time.

Can you wash screens yourself?

You can, carefully. Take the screen out, lay it flat, rinse with low water pressure, use a soft brush with mild soap, rinse again, and let it dry fully before putting it back. Avoid a pressure washer or stiff brush, which can stretch or tear the mesh, and avoid leaning screens against a dusty wall while they dry.

The tricky parts are keeping track of which screen goes where, getting them out of upstairs windows safely, and refitting them so they sit and slide the way they should.

What does a professional screen cleaning include?

Clearview's screen cleaning is a hand wash, not a quick rinse. Each screen is removed and labeled so it returns to the right window. Screens and frames are hand-washed to clear dust, pollen, and grime, then dried so no residue or water spots transfer to your clean glass. Finally, every screen is re-fit and inspected to make sure it sits and slides correctly and nothing is bent or torn.

Screen cleaning can be added to any window service, so it is easy to include with your next visit.

Should screens and tracks be done together?

Often, yes. Dirt from the screen frame and the outside of the glass ends up in the window track below. If your windows are sticking or the tracks look gritty, track cleaning pairs naturally with a screen wash.
