Lubricating Locks. This is a major telephone caller stat to us here at LocksOnline, how do I Lubricate my lock is asked by numerous customers on a daily basis, so much so we have put this tip on our new forum to give customers some advice that should help them maintain their locks and in turn those locks to look after their security.
The biggest problem with Lubricating locks is that people don’t. But more relevant to pad locks than most. Some manufacturers don’t normally lubricate their locks especially if their markets are also overseas. Fancy a company putting some grease in a lock and then selling it to Saudi Arabia. Within a month or two that grease is going to attract every grain of sand in the air and will clog up the lock in no time at all.
Then on the same hand not putting any lubricant in a lock will make it grind and seize up.
The biggest problem in the UK, believe it or not, is WD40 and even I have been guilty of picking up a can and spraying it in a lock. Works a treat don’t it, well for a while at least, then the same happens above in this country as it does in Saudi Arabia. admittedly, not as quickly but WD40 has two major problems with its consistency, one it stays wet and therefore, attracts dirt and dust, secondly it gets thicker as it get older, with the grit, dust and age, this is the ideal cocktail to jam up your lock, you end up spraying more WD40 into the lock with a hope to free it up but all you are doing is moving the grit and dust around. I have in the past used a bucket of paraffin to soak old padlocks and rinse them out, most of the time this cleans them enough to dry them out and then use a graphite dust to lubricate them.
OK, we need to put this all into context. Most of us have five lever dead locks on ones doors, If i was stripping a lock down to maintain it I would be putting a small amount of water proof grease on the bolt slide, and then use graphite power on the levers, that would it.
If you have a UPVC door with a euro cylinder, I would see no problem in using WD40 on the sliding mechanism, where the bolts throw into the door, but NOT in the cylinder where you put your key. again use a graphite dust or a silicon dry spray, Rocol is a good make. If you are into sailing you can by this stuff to spray on the sail glides. The idea of Silicon Dry Spray, is that the agent that propels the silicon evaporates and only leaves a thin film of silicon on the moving parts. Being dry has the amazing advantage of not attracting dust. Brilliant :-)
The down side with silicon, however, is that in some moving parts on locks and padlocks, it does not have the viscosity to maintain a wearing surface when parts are under pressure on each other and in these cases regretfully we have to use a thicker oil or sometimes grease. this in most cases does not matter as the weight of the moving parts would not be impeded by something so small as a grain of sand or dust.
So perhaps the moral of the story is use silicon or graphite in the really small moving parts like cylinders etc, when you come up to bigger parts like the bolts,latches etc you can up the grade of the lubrication.
I hope this article has helped, but perhaps every year make an effort to maintain your locks, give them a clean out and put some fresh lubricant in them. They will look after you for years to come.
Finally another product worth looking at is NON Fatty oil.
