Magic in the Padlock Hole: 45
Have you ever noticed that the bottom of a padlock contains a needle-sized hole? Padlocks have this capability built in for a cause. The drainage hole is present if you drop the padlock into water.
A frozen padlock could be hard to unlock until the water thaws, creating corrosion or causing the padlock to get trapped.A few drops of oil in the hole can do wonders if the padlock is rusty and the key won’t turn due to rust buildup.
