I’m right there with you on the hardware roulette. When we moved in last year, I thought “marine grade” meant set-it-and-forget-it, but nope—my deck screws started showing rust spots after the first big storm. I’ve read that 316 stainless is supposed to be way better than 304 for salty air, but like you said, it’s a pain figuring out what you’re actually buying. Sometimes I wonder if the labels are just marketing.
Rinsing with fresh water helps a bit, but I always forget after a long day. I tried one of those waxy sprays on my gate hinges and it seemed to slow things down, but it left a weird residue. Honestly, I’m starting to think swapping out hardware every few years is just part of the deal. At least I know now not to trust the “marine” label blindly... coastal life definitely keeps you on your toes.

I get where you’re coming from, but I’m stubborn and refuse to accept defeat by salty air. I started using silicon caulk on screw heads and hinge joints—messy, but it’s kept rust at bay way longer than the sprays. It’s not pretty, but neither is orange streaks down my white railing. Might be worth a shot before giving in to the hardware swap cycle...
I’ve tried the caulk trick too, but honestly, it just looked too sloppy for my taste. What’s worked better for me is switching to stainless hardware, even though it costs more up front. I’m not a fan of replacing stuff every couple years either, but after a few rounds of sanding and repainting, I figured the extra investment was worth it. The sprays never lasted more than a season in my experience... Maybe it depends on how exposed your setup is?
Stainless hardware’s solid, but I’ve seen it pit and stain too if you’re right on the coast—especially with cheaper grades. Sometimes hot-dip galvanized holds up better in really salty air, even if it doesn’t look as sharp. The sprays are a waste, agreed... they just don’t last with constant exposure. If you’ve got shade or windbreaks, that can help slow things down, but nothing’s totally maintenance-free out here.
I’ve had similar experiences with stainless—people assume it’s bulletproof, but the cheaper 304 stuff pits fast right on the water. Even 316 isn’t immune if you’re just a few blocks from the surf. Galvanized can actually last longer in some spots, though it definitely doesn’t win any beauty contests after a few years. I’ve seen powder coating help a bit, but once it’s chipped, rust creeps in quick. Maintenance is just part of the deal near the coast, no way around it.
