How to clean an antique lock

If you meancleaning an ancient lock and maybe it is an antique piece, better if you put yourself aside and contact an expert metal restorer. Thereancient lock, if rusty, it should be disassembled and properly treated. Like? It depends on the state of conservation.

If it is simply rusty, there are those who recommend letting it "rest" in water for 72 hours so that the excess iron oxide can detach naturally, without making any filings. Already, abrasive paper is banned in the restoration and recovery ofantique locks! After 72 hours, the lock should be cleaned inside with a specific product and outside with a protective wax.

If theancient lockit is very rusty even inside the hole, experts in the field use oxalic acid or electrolysis processes to facilitate the detachment of rust and accumulated dirt.

How to clean an old lock

If thedoor lockit's simplyoldand your purpose is simply to make it work (so that it can allow you to use the key effectively), you can use a spray can of compressed air (you can find it on Amazon or at the hardware store) and clean the gap that allows the access to the key. Once this is done, you can spend some dry type lubricantas I will explain to you for the cleaning of the classicallock locked.

How to clean a lock that gets stuck

If you are dealing with a modern lock that, due to oxidation or dirt, does not allow you to turn the key easily, in addition to cleaning work, you will need to perform lubrication work. Like? Using a dry cleaning lubricant!

If you already have an oil type lubricant at homeSvitol (Arexons),WD-40, Ambrosol…. check the composition. The classic ones you find on the market are generally oily, so if yourslock is dirtythey would make the situation worse. Like? These lubricants, even if they have an apparently positive effect (in fact after use it becomes easier to open and close the door), going togrease and wetthe mechanism of the lock, go to incorporate the particles of dust and rust flaking off the same mechanism. As long as the lubricant stays wet, the lock works… but when it dries, not only does the problem return but the lock locked it will be more difficult to heal.

Dry lubricants, on the other hand, are based on PTFE, to be clear ... if there is any woman who reads me, it is Teflon, the same substance that until recently was used to make the non-stick patina of the pans! This material does not grease or "mess" the lock mechanism but will create a protective coating that is not very used to friction (therefore indirectly lubricated!). By lowering the friction between the components of the lock, it will unlock easily. So if you are wonderinghow to unlock a locked lock from dirt and rust, just use the right Teflon-based product.

Lubricant to clean and unlock the lock

If you go to a trusted hardware store, make sure they are giving you a PTFE-based lubricant. Generally it is written on the purchase package but brands likeSvitol, they do not specify it.

For example, in addition to the classic Svitol, at the hardware store you can find "Svitol dry" with the inscription "Dry". While if the hardware store offers you the WD-40 lubricant, make sure that it says "Lubricate with PTFE", while many other manufacturers simply add the words "dry lubricant“.

In addition to the hardware store, also on Amazon you can find specific lubricants to clean, protect and above all unlock a dirty lock. There is no shortage of all the brands mentioned so far. I want to clarify thatIdeeGreen.ithas no connection with the manufacturers mentioned in this article, so feel free to choose the dry lubricant you prefer (or maybe just the cheapest!).

To get an idea of ​​the products mentioned and the cost of a can of dry lubricant, I invite you to visitthis Amazon page where you can see different proposals and get an idea of ​​how the product should be (the packages between oil lubricants and dry ones are very similar, the wording and in some cases the colors change. For example, svitol classico has an entirely yellow, while the PTFE svitol has a yellow and blue packaging!).
