All;
Our Galley to Companion way latch was recently getting "hinky", and simple disassembly, cleaning, and generous lubrication of each sleeve and part prior to reassembly completely renewed it.
Same with our Salon/Pilot house door latches.. They could stand to be re-plated sometime soon, but when I renewed the doors complete with a new teak panel and paint/varnish as necessary, they're like new again.
Let 3-in-1 oil be your friend I guess, is my offering here.
