How To Prevent Rusting of Door Locks?

1.Inject a specialized lubricant into the lock core

Pour the lubricant into the lock cylinder and use the key to rotate it back and forth a few times. This method achieves a smooth effect, making the lock less prone to rusting. It should be noted that do not add cooking oil or engine oil from home to the lock cylinder. Although this method can achieve a smooth effect, due to the high viscosity of these oils, over time, more dust and debris will be sucked into the lock core, sticking to the springs inside, making it more difficult to open the lock.

2. Apply graphite powder into the lock core groove

You can apply toner to the new lock. If you don't have it at home, you can use the powder of a pencil lead and apply it in.

3. Using rust removers

The primary component of rust remover is hydrochloric acid, which can remove rust on metal surfaces and will not corrode other parts of the workpiece. The rust removal speed is also particularly fast. Spray the rust remover directly on the lock core opening, wait for a while, then insert the key into the left and right and twist it to open it.
