Preventing Rust from Forming on Floor Vents

How can you prevent rust from forming on new floor vent covers?

Why are they getting rusty? I would address that issue first. Is this in an area that gets wet such as a bathroom or kitchen? Is it under a window that gets left open? They should not be getting so wet to rust. Maybe the vent needs to be moved or a leak addressed? If in a bathroom maybe a vent/fan needs to be installed or used. You could coat the vent with a clear poly sealer for outdoor use, but most of those are made for wood applications, or try painting it with rustoleum paint, which is designed to prevent rust.

I would suggest to remove the covers and spray them lightly with clear acrylic sealer. The sealer is available in the hardware stores or any craft store.

Our vents/registers get a little rusty, and I think it's because we have a humidifier attached to our furnace. We've painted them and eventually they get a little rusty again...the clear acrylic sealer suggestion sounds like a good idea and is one I plan on trying.

Lifting when you wash the floors helps. Just replace as soon as the floor dries.
