Signs it is getting to your locks
- The key is hard to insert or turn.
- Green or white crust on brass, or rust spots.
- The knob or lever feels gritty.
How to look after them
- Rinse exterior hardware with fresh water now and then, then dry it.
- Use a dry lubricant made for locks, such as graphite or a PTFE dry spray. Skip household oil, which collects grit.
- Work the key and the deadbolt a few times after lubricating.
- Replace locks that keep sticking before the key breaks off inside.
Finishes that last
Look for stainless steel or locks with a lifetime or PVD finish meant for coastal homes. Solid brass with a living finish will age, but will not rust through.
