Advice from Andrey Zhilin, Coastal Cleaning Expert at Sharky Destin
If you live in Destin, you’ve seen it — the haze that seems to appear on your windows overnight.
You clean it, it looks fine for a day or two… and then the dullness returns.
That’s not dust.
That’s salt film — the invisible layer left behind by coastal air every single day.
And it’s the reason even brand-new windows can look old within months if you don’t treat them properly.
1. The Chemistry of Salt Film
Destin’s ocean air carries microscopic salt particles that float miles inland.
When that air cools at night, it condenses on glass surfaces — leaving behind salt crystals when it dries.
Over time, those crystals:
- Etch the glass surface, causing micro-scratches.
- Dull reflections and reduce transparency.
- Trap moisture that feeds mildew around window frames.
Once etched, the damage is permanent. That’s why prevention is the key.
2. Why Regular Cleaning Doesn’t Work
Most homeowners just spray glass cleaner and wipe.
The problem? Regular cleaners are alkaline, while salt is slightly acidic.
The two react — spreading residue instead of removing it.
That’s why streaks always return after a few days.
Professional solution:
At Sharky Destin, we use neutralizing agents that dissolve salt crystals on a molecular level before cleaning.
This removes the residue completely, leaving the glass truly clear and static-free.
3. The Frames Matter Too
Salt doesn’t just affect glass — it corrodes window frames, especially aluminum and steel.
It builds up in corners, locking in moisture that eventually eats through the coating.
What to do:
- Rinse frames with fresh water once a week.
- Dry thoroughly with a soft towel.
- Apply a silicone-based protective finish every 3–4 months to repel moisture.
A few minutes of prevention can save you thousands in frame replacement.
4. The Best Time to Clean Coastal Windows
In Destin, October and November are ideal — the air is dry, winds are mild, and there’s less salt spray.
If you deep-clean now, the results last much longer.
Avoid cleaning right after rain or in midday heat — both leave mineral marks that set faster.
5. The Sharky Finish
At Sharky Destin, our window service isn’t just “washing glass.”
We de-ionize the rinse water, neutralize salts, and polish surfaces with anti-static protectants.
That means fewer streaks, longer clarity, and windows that resist future buildup.
Because in coastal living, visibility is more than beauty — it’s peace of mind.
Final Thought
The salt film isn’t dirt — it’s the ocean reminding you it’s still there.
But with the right care, you can enjoy the view without letting the sea move in.
