Lock Lubrication

November is a great time to lubricate door hinges and locks, especially if they are outdoors. It is the last chance you will have before freezing daytime temperatures begin to move in if you are in one of the colder climates.

Before lubricating, it is best to clean the lock by flushing it with with brake cleaner or a good penetrating fluid. Next, check the lock, deadbolt, hinges and any other moving parts to be sure they move freely.

Afterwards, you are ready to lubricate. There are many lubricant products available in the marketplace for this type of application. However, you will want to select one that will adequately meet your needs. Please consider the following:

Colder climates -- Will the lubricant function in freezing temperatures?
Warmer climates -- Will the lubricant withstand high heat without evaporating?
High Humidity/Moisture -- Will the lubricant withstand rust/corrosion?
Durabilty -- Will the lubricant cake or gum creating mechanical problems over time?

Once you have selected your lubricant, apply some to the opening of the keyway. It helps to insert the key to move the lubricant inside and work its way into the lock mechanism. Be sure to wipe down the key and outside of the lock with a rag or towel when you are done since some excess lubricant will inevitably be there. Next, lubricate any hinges, cables, handset/handle or deadbolts in a similar manner. Always allow the lubricant to penetrate for a minute or so before wiping off any excess.

We would recommend resisting the temptation to lubricate with graphite powder or the ubiquitous WD40 since both have a tendency to collect dust and dirt -- gumming and caking will eventually occur making the lock inoperable.
