Use a small amount of graphite powder in the lock
Cover exterior locks during severe cold snaps
Avoid breathing directly into the lock (adds moisture)
When to Use De-Icer
Commercial lock de-icers work well, but the beauty of this trick is that it:
Requires no special products
Works anywhere
Is always available when you need it most
That’s why my uncle still swears by it after all these years.
