How to prevent door locks from rusting

It should be noted that many people like to add cooking oil or engine oil to the lock cylinder when the lock cylinder is rusty and does not turn.

Although this method can have a smooth effect, due to the stickiness of these oils, it will suck more dust and debris into the lock cylinder, sticking to the spring inside, making it more difficult to open the lock.

2. Wipe graphite powder into the lock cylinder groove.

Graphite powder has a smooth metallic effect. We often find that there will be some black and gray on the new locks we buy, which is left by the merchant when he adds graphite powder to the lock cylinder.

3. Use rust remover.

The primary ingredient of the rust remover is hydrochloric acid, which can remove rust on the metal surface, and together with it will not corrode other parts of the workpiece, and the speed of rust removal is also very fast. Spray the rust remover directly on the lock cylinder mouth, wait for a while, and then stab the key left and right to twitch to open it.
