Have stainless steel ladder rails/treads that are experiencing rust at the holes the bolts go through to fasten the treads to the rails. I think the culprit is the bolts. If I remove the treads, and the nuts/bolts, then treat them with naval jelly to remove rust, then reinstall the treads, will this be sufficient to prevent or at least delay the return of rust? The area around holes in the ladder rails where bolts go through to attach treads are underwater & also have rust. Is there a way to remove that rust? Thanks very much.
