Live within a few miles of the Gulf or the bay and you'll notice it: door hinges that squeak early, light fixtures that pit and dull, an AC cabinet growing freckles of rust. Salt-laden air settles on every outdoor surface, pulls moisture from the humidity, and quietly eats metal. You can't stop the breeze — but a simple rinse-and-protect routine slows the damage to a crawl.
The monthly fresh-water wipe-down
Salt does its damage while it sits. Once a month, wipe exterior metal with a cloth and plain fresh water — door handles and locks, hinges, light fixtures, railings, house numbers, and mailbox hardware. For larger areas, a gentle hose rinse does the job. That's it; the entire routine takes fifteen minutes and removes the salt film before it bites.
Protect what you've cleaned
- Car wax on fixtures: a thin coat of automotive paste wax on painted and powder-coated metal (light fixtures, railings, aluminum frames) seals the surface for months. It's the same trick coastal marinas use.
- Silicone or corrosion-inhibitor spray on hinges, locks, and sliding-door hardware keeps salt out of the moving parts. Wipe off the excess so it doesn't collect dust.
- Outdoor stainless steel (grills, outdoor kitchens) isn't immune — "stainless" stains plenty near the coast. Clean with soapy water, dry, and apply a stainless polish; those orange "tea stains" wipe off with a non-abrasive stainless cleaner if you catch them early.
Don't forget the AC condenser
Your outdoor AC unit is the most expensive thing the salt air touches. With the power off at the disconnect, rinse the coil fins gently with a garden hose (never a pressure washer — fins bend like foil) a few times a year. Coastal HVAC techs recommend it for a reason: a salt-crusted coil works harder, dies younger, and costs four figures to replace.
