Locksmith Lesson of the Day
Don’t ever use WD40 on a lock! It is a penetrant and not a lubricant. You might think that using WD40 on a frozen bolt could help “unstick” it, however after a period of time the lock becomes gummy. It actually can keep a lock from working as all of the dust and dirt sticks to the lock and the lock parts no longer move smoothly. The effect is doubly bad in humid or rainy weather as water as the WD40 becomes really sticky and syrupy. This then leaves you in a situation where you have to call a locksmith and he must then wash the sticky lock parts using thinner. Sometimes the locksmith might even have to replace the lock. Save yourself the headache and some money and call yourself a locksmith.
