If your double pane windows look foggy, hazy, or cloudy between the two panes of glass — and wiping both sides does nothing — here is the honest answer Naples homeowners need: you cannot clean between the panes.
A double pane window is a sealed insulated glass unit. The two panes are bonded together at the factory with a sealed, gas-filled or dry air space between them. There is no opening, no access — the space between the glass is closed by design.
When you see fog or haze trapped inside that space, it means the seal has failed. Moisture has gotten into the sealed unit and condensed between the panes. No cleaning solution, tool, or technique can reach in there — the foggy appearance is permanent until the glass unit is dealt with.
The only real fixes for a fogged double pane window are replacing the insulated glass unit (the sealed glass panel) or replacing the whole window — both of which are jobs for a window or glass company, not a cleaning service. We want to be straight with you about that rather than sell you a clean that physically cannot work.
You cannot clean between the panes of a double pane window — it is a sealed unit. Fog trapped inside means the seal has failed, and the only real fixes are replacing the glass unit or the window. That is a glass company’s job, not a cleaning service’s.
Before assuming the worst, it is worth confirming where the haze actually is. The test is simple.
Wipe the inside surface, then the outside surface. If the haze wipes away from either side, it was just surface dirt, film, or hard water residue — and that is something we can clean.
If the haze stays after wiping both sides, the fog is trapped between the panes, inside the sealed unit. That is seal failure, and no surface cleaning will touch it.
A few other tells of a failed seal: the fog often changes through the day with temperature — heavier in the morning, lighter in the afternoon — and over time you may see mineral or moisture staining etched on the inner glass surfaces that no longer clears at all.
If you are not sure which one you are looking at, we can take a look during a free on-site visit and tell you honestly — surface cleaning we can handle, or seal failure that needs a glass company.
Interior Glass Surfaces
Dust, film, fingerprints, and grime on the inside surface of the glass — cleaned streak-free with the squeegee technique.
Exterior Glass Surfaces
Salt film, pollen, weather grime, and dirt on the outside surface — including second-story glass handled safely.
Hard Water Spotting
Mineral deposits on the glass surface from irrigation overspray — removed with a dedicated mineral treatment.
Fog Between The Panes
Trapped fog inside a sealed double pane unit is seal failure — not a cleaning issue. This needs glass unit or window replacement.
For the window cleaning we can do — every interior and exterior glass surface — all pricing is based on a free on-site inspection. The number of windows, the number of stories, and whether hard water treatment is needed determine the final price. These are honest starting ranges for Naples:
