As you know I live on a small island in the Bahamas right now. This is Cupid’s Cay and as you can see it has a causeway to the mainland but isn’t really that large. Given the proximity to the ocean salt is everywhere and always in the air.
It’s not only here on the Cay but anywhere that is close to the ocean and the effects are similar.
The salt is just always in the air and settles on everything whether that is inside or outside the house. There’s nothing that you can do other than plan on replacing parts as they are needed and in the meantime spray them with WD-40 to keep them functioning as long as possible.
Ah life on an island!
