How to deal with rusty door locks?

Rust on door locks is caused by various reasons, and before handling it, it is important to determine whether it is surface rust or lock core rust.

Solution:

1. Rust on the surface of the lock

① If the surface rusts, just use rust remover to remove the rust spots. First, spray the rust remover on the surface, wait for the rust spots to fall behind, and then clean them with a cloth.

② You can use coarse sandpaper to remove the rust on the surface of the door lock, use fine sandpaper to polish the surface of the door lock, apply clear paint evenly on the surface of the door lock, and wait for it to air dry before use.

  2. Lock cylinder rusted

① If the lock core rusts, pour some rust remover into the lock core. After a while, insert the key into the lock core and rotate it a few times, and the rust spots will fall off.

② You can add some kerosene to the lock core because kerosene has the effect of dissolving rust, which can eliminate the rust on the lock.

  3. Replace the lock cylinder or directly replace the lock

If the above method does not work, it indicates that the time for your lock to be used has passed, and the most suitable method at this time is to either replace the lock cylinder or lock.
