Near the ocean, windows do not just get dirty: they get salted. Airborne spray dries on the glass as a fine mineral haze that a dry rag spreads instead of removes, which is why oceanfront homes in Pompano Beach and Lauderdale-by-the-Sea can clean a window on Saturday and see the haze again within weeks. Window cleaning on the coast is a maintenance rhythm, not a once-a-year event: quarterly near the water, twice a year inland.

If you only remember one rule: salt film is not dirt on the glass, it is a coating that needs to be dissolved and lifted, not wiped around.
Why does the coast make it worse?
Salt is hygroscopic: it keeps pulling moisture from the air, so the film never fully dries out and dust bonds to it. East-facing glass on the barrier islands takes it directly; even a few blocks inland, onshore wind carries enough spray to matter. The same film is a daily fact of condo life on the water, as covered in condo cleaning from Galt Ocean Mile to Downtown.
What does a professional visit include that a squeegee at home does not?
- Both sides of the glass: the outside face is where the salt lives
- Frames and sills: where dissolved salt and grit drain and dry
- Tracks: the channel that grinds every time you slide the door
Tracks are the quiet failure point: years of grit in a sliding-door track means the door drags, and the glass above it never looks finished no matter how clean the pane is.
Can you do it yourself between visits?
On ground-floor glass, yes, and the method matters far more than the tool. Salt has to be dissolved before anything is wiped, so the order is rinse, wash, then squeegee. Going straight in with a cloth drags dry crystals across the pane, which is how coastal glass picks up fine scratches over the years.
Two things make the difference. Give the glass enough water to actually carry the salt away rather than move it around, and work from the top down so the run-off never crosses a surface you already finished. Then dry the frame and sill, not just the pane: the salt that drained off the glass is now sitting there.
Above the ground floor the answer changes. Outside faces on an upper storey are not a homeowner job, and in most buildings on the water they are not even permitted: access goes through the association, which is the same access question covered in cleaning a 1960s condo tower.
What happens if the film is left alone?
It stops being a cleaning problem and becomes a repair one.
Salt holds moisture against whatever it sits on. On the glass itself, mineral deposits left through enough wet seasons begin to etch the surface, and etching does not wash off: the haze becomes permanent and the pane has to be replaced to look clear again.
The frames go first, though. Aluminium frames, rollers and screen mesh corrode where salt and moisture sit together, and a slider that has been grinding salt through its track for years stops running smoothly long before anyone blames the window.
That is the real argument for a rhythm instead of a rescue. Quarterly on the water is not about appearance, it is about never letting the film sit long enough to do the damage that cleaning cannot undo.
How often should coastal windows be cleaned?
The rhythm the glass itself asks for: quarterly near the coast, twice a year for most properties inland. Pairing it with a one-time deep cleaning or a move-out visit is common: clear glass is the finishing touch an empty room shows off first.
