Best Lock Lubricant - Buyers’ Guide

What type of lubrication is normally most effective for a lock?

Graphite-based lubricants are quite popular and often used as the preferred lubricants for most locks. They can, however, get messy. Other lubricants such as Teflon and Silicone are also being utilized much more frequently now.

What are some things to consider when purchasing a lock lubricant?

It’s actually a lot more complicated to buy a lock lubricant than it sounds. Some of the factors you can think about which will help you determine which lock lubricant would be most suitable for you are:

  • Straight Straw or Flexible Straw?

It’s a great idea to think about what kind of straw comes with the lock lubricant you intend on buying. You can make this decision by thinking about what other uses you may have for the lubricant. Think about what else you'll be using it on except locks and also by thinking about what type of locks you’re going to use it on. Some locks have a lot of moving parts and in-depth mechanisms. It may be an issue to reach them if you have a lock lubricant with a straight straw delivery system.

  • Legality

There are certain laws set in place when it comes to the production of lubricants and these laws can vary heavily depending on where you live. Most reliable and top lock lubricant brands produce their lubricants within the confines of the law. However, it’s important that you check what the laws in your region are before you buy them, especially if you’re ordering online.

  • Weather

Before buying a lock lubricant, it’s important to consider the weather of the region that you live in. Many common lock lubricants tend to stop working at colder temperatures. This is because their reaction with the lock’s surfaces is slowed down at lower temperatures. There do exist special lock lubricants that can work at colder temperatures so if you live in such a region, you should seek such a product out and buy that.

How can I effectively apply lock lubricant without wasting too much of it?

No matter what lubricant you get, it’s going to come with its own set of instructions. What you need to understand is that if you follow these instructions to a T, you will end up applying the correct amount of lock lubricant on your lock. You won’t have trouble with any extra lubricant being wasted. It’s important for you to follow these instructions as it will help you prevent wasting lubricant. Also, your lubricant might not work properly if you don’t apply it correctly.

If you don't apply your lubricant properly, it could lead to the sticking of smaller parts inside your lock. this could then lead to the lock becoming rigid or even breaking. If the inner workings of your lock become rigid, it could also be easily pried open by a burglar. 

Are lock lubricants flammable?

No. Most high-quality lock lubricants are non-flammable. However, we still recommend that you keep it away from any open flames.

Are lock lubricants toxic?

Most top lock lubricant manufacturers make an effort to make sure that their products are non-toxic. However, we still strongly urge you to be careful not to ingest them and seek medical help immediately if something like that does happen.

Best Lock Lubricant - FAQs

I just spilled some of my lock lubricant. How can I clean it effectively?

  • If a spill occurs, the best way to deal with it is by cleaning it up using a dry cloth such as an old rag or shop towel. You can make use of paper towels if you want but cloth towels are generally better as they are more absorbent.
